BACKGROUND OF THE INVENTION1. Field of the Invention
This invention is generally directed to access devices for introducing and delivering a catheter cannula or sheath into an artery, vein, vessel, body cavity, or drainage site.
2. Description of the Related Art
A preferred non-surgical method for inserting a catheter or vascular sheath into a blood vessel involves the use of the Seldinger technique, which includes an access needle that is inserted into a patient's blood vessel. A guidewire is inserted through the needle and into the vessel. The needle is removed, and a dilator and sheath combination are then inserted over the guidewire. The dilator and sheath combination is then inserted a short distance through the tissue into the vessel, after which the dilator and guidewire are removed and discarded. The catheter may then be inserted through the sheath into the vessel to a desired location.
A number of vascular access devices are known. U.S. Pat. Nos. 4,241,019, 4,289,450, 4,756,230, 4,978,334, 5,124,544, 5,424,410, 5,312,355, 5,212,052, 5,558,132, 5,885,217, 6,120,460, 6,179,823, and 6,210,332 disclose examples of such devices. None of these devices, however, has the ease and safety of use that physicians and other healthcare providers would prefer and, thus, there is a need for an easier-to-use and safer vascular access device, especially one that would clearly indicate when a blood vessel has been punctured.
SUMMARY OF THE INVENTIONThe present invention involves several features for an access device useful for the delivery of a catheter or sheath into a space within a patient's body, such as, for example, a blood vessel or drainage site. Without limiting the scope of this invention, its more prominent features will be discussed briefly. After considering this discussion, and particularly after reading the Detailed Description of the Preferred Embodiments section below in combination with this section, one will understand how the features and aspects of this invention provide several advantages over prior access devices.
One aspect of the present invention is an access device for placing a medical article within a body space. The device has a needle section that includes an elongated body and a needle hub. The elongated body has distal and proximal ends. The distal end is configured for insertion into a patient's body. The proximal end is coupled with the needle hub. The device further includes a dilator portion including a dilator and a dilator hub. The dilator is coaxially disposed and slideable over the elongated body of the needle section with the dilator hub being disposed distal of the needle hub. The device further includes a sheath section that has a sheath and a sheath hub. The sheath is coaxially disposed and slideable over the dilator with the sheath hub being disposed distal of the dilator hub. The device further includes a first locking mechanism operably disposed between the needle hub and the dilator hub to inhibit at least unintentional axial movement between the needle section and the dilator portion when the first locking mechanism is engaged and a second locking mechanism operably disposed between the dilator hub and the sheath hub to inhibit at least unintentional axial movement between the dilator portion and the sheath section when the second locking mechanism is engaged. Each of said first and second locking mechanisms is configured to be engaged by moving the respective hubs in a non-axial manner relative to each other. The first locking mechanism is configured to move in a manner different from the manner in which the second locking mechanism is engaged.
Another aspect of the invention is an access device for placing a medical article within a body space. The device includes a needle section including an elongated needle body with a sharp distal tip and a needle hub from which the needle body extends. The device further includes a dilator portion that includes a dilator and a dilator hub. The dilator is coaxially disposed and slideable over the needle body with the dilator hub being disposed distal of the needle hub. The device further includes a sheath section that includes a sheath and a sheath hub. The sheath is coaxially disposed and slideable over the dilator with the sheath hub being disposed distal of the dilator hub. The device further includes a locking mechanism disposed within the dilator and selectively operating between the needle body and the dilator. The locking mechanism is configured to arrest axial movement of the needle body at least in the distal direction once the distal tip of the needle body is drawn into the dilator portion to sheath the distal tip.
Yet another aspect of the invention is an access device for placing a medical article within a body space. The device includes a dilator hub that has a passageway configured to receive an elongated needle. The needle has at least one side receptacle. The device further includes one or more fingers or tangs disposed in the dilator hub and configured to engage with the at least one side receptacle at least when the needle is retracted through the passageway.
Additionally, a releasable interlock can be provided in some embodiments to inhibit relative rotational movement between the needle section and the dilator section, at least when the needle is inserted into a patient. By inhibiting such relative rotational movement, communicating side openings in the needle and the dilator can be held in alignment to provide a simplified passageway through which the blood or fluid may flow. Thus, when the needle enters a blood vessel or drainage site in the patient, blood or other body fluid quickly flows into the passageway. The resulting blood or fluid flash is visible through the sheath section (or catheter) to indicate that the needle tip has entered the vessel or drainage site.
For example, but without limitation, the dilator portion or section can comprise, in some embodiments, a dilator hub and dilator having one or more side openings. The dilator hub may have a luer connection and a releasable locking mechanism. The releasable locking mechanism can be configured to releasably engage and secure the dilator section to another part, such as the needle hub. When the needle hub and the dilator hub are releasably locked to prevent rotation therebetween, one or more of the side openings in the dilator are aligned with one or more side openings in the needle. The locking mechanism can also be configured to inhibit unintentional relative axial movement between the needle and the dilator.
The sheath section preferably, but not necessarily, includes a sheath and sheath hub. The sheath may be made partially or completely from a clear, translucent, semi-opaque, or transparent material. Such transparent, translucent, semi-opaque and clear materials allow a clinician the ability to see when blood or other body fluids flows into the needle, through the needle side opening(s), through the side dilator opening(s), and into the viewing space between the dilator and sheath.
These and other aspects of the present invention will become readily apparent to those skilled in the art from the following detailed description of the preferred embodiments, which refers to the attached figures. The invention is not limited, however, to the particular embodiments that are disclosed.
These and other features, aspects, and advantages of the invention disclosed herein are described below with reference to the drawings of preferred embodiments, which are intended to illustrate and not to limit the invention.
The present disclosure provides an access device for the delivery of a catheter or sheath to a blood vessel or drainage site.
Preferably, the needle section 20 locks to the dilator portion 28 via a lock mechanism 26. The lock mechanism 26 may comprise an engaging mechanism such as hinged clips 27 with actuator sides 29. The hinged clips 27 may releasably engage and secure to corresponding catches 25 on the dilator portion 28. In some embodiments, the clip sides 29 engage and secure the dilator portion 28 by clipping to the outer lip of a luer connection 33 on the dilator portion 28. Although hinged clips 27 are shown, the lock member 26 may comprise any suitable engaging mechanism known in the art. In the illustrated embodiment, as best seen in
Similarly, the sheath section 58 is secured to the dilator portion 28 through a lock member 59. The sheath section 58 may, preferably, comprise a twist lock member 59 so that the user may releasably engage and secure the dilator portion 28 to the sheath section 58. In some preferred embodiments, the dilator portion 28 comprises teeth or prongs that are configured to mate or attach to corresponding areas on the sheath section 58. Preferably, the needle 20, dilator 28 and sheath 58 are releasably locked so that a physician or user may remove sections or portions of the access device as needed for treatment.
As discussed above, in preferred embodiments, the needle hub 21 comprises the lock member 26. The lock member 26 may be configured to lock or secure another part such as, for example, the dilator portion 28 or the sheath section 58, to the needle section 20. As shown most clearly in
As shown most clearly in
Additionally, the dilator 30 may be coaxially mounted to the needle 22 by slipping a hollow section 113 of the dilator 30 over the needle 22 and releasably securing the dilator hub 32 to the needle hub 21. Preferably, the proximal end 45 of the dilator hub 32 is configured to mechanically fit and interlock with the needle lock member 26 to inhibit at least some rotational and axial motion. More preferably, the dilator 30 is releasably mounted to the needle 22 so that the dilator 30 can be mounted and released, or vice versa, from a coaxial position relative to the needle 22.
The sheath hub 53, as best seen in
In some applications, the wings 55 are sized to provide the healthcare provider with leverage for breaking apart the sheath hub 53. For example, the sheath hub 53 may comprise a thin membrane 61 connecting the halves of the sheath hub 53. The membrane 61 is sized to keep the halves of the sheath hub 53 together until the healthcare provider decides to remove the sheath hub 53 from the access device. The healthcare provider manipulates the wings 55 to break the membrane 61 and separate the sheath hub 53 into removable halves.
Preferably the dilator 30 may be coaxially positioned to minimize the annular space 36 between the needle 22 and the dilator 30. The inner surface 38 of the dilator 30 need not, though it can, lie directly against the outer-surface 40 of the needle 22. Preferably, the annular interface 36 between the outer-surface 40 of the needle 22 and the inner surface 38 of the dilator 30 is minimized to inhibit the flow of blood or its constituents (or other bodily fluids) into the annular interface 36 between the dilator 30 and needle 22. Advantageously, this feature minimizes the blood's exposure to multiple external surfaces and reduces the risk of contamination, infection, and clotting.
The sheath 54 is made partially or completely from clear, semi-opaque, translucent, or transparent material so that when blood flows into the needle 22, (1) through the needle side opening 34, (2) through the dilator side opening 111, and (3) into an annular space 60 between the dilator 30 and the sheath 54, the physician or healthcare provider can see the blood. This will indicate to the physician or healthcare provider that the bevel tip 108 of the needle 22 has punctured a blood vessel.
More preferably, the dilator 30 can be coaxially mounted to the needle 22 such that at least one side opening 34 disposed on the needle 22 is rotationally aligned with at least one side opening 111 on the dilator 30. In some embodiments, the needle 22 and dilator 30 may (both) have multiple side openings 34, 111 where some or all of these side openings 34, 111 can be rotationally aligned. Preferably, the needle 22 and dilator 30 maintain rotational alignment so that blood flows substantially unobstructed through the needle side opening 34 and dilator side opening 111.
While the side openings 34, 111 in the needle 22 and the dilator 30 are aligned in the embodiment illustrated in
In accordance with another aspect of the present invention, there is provided an interlock or interconnection between the needle 22 and at least one of the dilator 30 or dilator hub 32. The interlock or interconnection inhibits the bevel tip 108 disposed on the distal portion 106 of the needle 22 from being advanced beyond the distal end of the dilator 30 once the dilator 30 has been advanced over the needle 22 during use. The dilator 30 thus sheaths the sharp bevel tip 108 of the needle 22 to inhibit accidental needle sticks from occurring.
The arm 117 may be axially aligned with the arm 119. Alternatively, the arms 117, 119 may be offset from each other in a radial direction. The arms 117, 119 may be slightly rotated relative to each other or disposed at different radial locations on the inside surface of the dilator 30. The tang or arm 117, 119 may move in a direction generally transverse to a longitudinal axis of the needle body when engaging the receptacle or hole 131.
The locking mechanism 115 is illustrated on the dilator 30. However, the needle 22 may instead comprise the locking mechanism 115. In the illustrated embodiment, the needle 22 comprises a receptacle, recess, opening, or hole 131 which interacts with the locking mechanism 115 of the dilator 30 when the needle 22 is sufficiently retracted into the dilator 30. The receptacle, recess, opening, or hole 131 may extend entirely around the needle 22 forming an annular groove or around only a portion of the needle 22.
For embodiments that have arms 117, 119 disposed at different radial locations on the inside surface of the dilator 30, the needle 22 may comprise more than one recess, opening, or hole 131. The multiple recesses, openings, or holes 131 are disposed at radial locations around the outer surface of the needle 22 that correspond to the radial spacing of the arms 117, 119 around the inside surface of the dilator 30.
The arm 117 is coupled to the base 121 via hinge 127 and rotates from an unlocked position to a locked position in a counter-clockwise direction. The arm 119 is coupled to the base 123 via hinge 129 and rotates from an unlocked position to a locked position in a clockwise direction. In the illustrated embodiment, each arm 117, 119 rotates approximately 90 degrees between the unlocked position and the locked position. However, the locked position may be more or less than 90 degrees from the unlocked position. The arms 117, 119 need only rotate a sufficient amount to allow their distal ends to abut against a portion of the perimeter of the recess, opening, or hole 131.
The recess, opening, or hole 131 in the needle 22 locally increases a gap located between an outside surface of the needle 22 and an inside surface of the dilator 30 a sufficient amount to allow the arms 117, 119 to rotate about their respective hinges 121, 123 and towards the locked position. When the arm 117 is in the locked position, the needle 22 is inhibited from relative axial movement with respect to the dilator 30 in a proximal direction. When the arm 119 is in the locked position, the needle 22 is inhibited from relative axial movement with respect to the dilator 30 in a distal direction.
The one or more bases 121, 123 are attached to or integral with the dilator 30 and extend generally towards the coaxially aligned needle 22. The bases 121, 123 are sized so as to not interfere with movement of the needle 22 through the dilator 30 while providing hinge points for attachment of the arms 117, 119. The arms 117, 119 are sized to allow movement of the needle 22 through the dilator 30 when the arms 117, 119 are in the unlocked position. The hinges 127, 129 permit the arms 117, 119 to move from the unlocked position illustrated in
Each arm 117, 119 can separately move to the locked position when the arm 117, 119 is axially aligned with the recess, opening, or hole 131 in the needle 22. Once in the locked position, the hinge 127, 129 does not permit the arm 117, 119 to move back to the unlocked position. In some embodiments, the hinges 127, 129 slightly bias the arms 117, 119 to move towards the locked position. For example, the tang or arm 117, 119 can be biased toward the receptacle, recess, opening, or hole 131.
The locking mechanism 133 is illustrated on the dilator 30. However, the needle 22 may instead comprise the locking mechanism 133. In the illustrated embodiment, the needle 22 comprises a recess, opening, or hole 139 which interacts with the locking mechanism 133 of the dilator 30 when the needle 22 is sufficiently retracted into the dilator 30. The receptacle, recess, opening, or hole 139 may extend entirely around the needle 22 forming an annular groove or around only a portion of the needle 22. The needle 22 may comprise more than one recess, opening, or hole 139. The multiple recesses, openings, or holes 139 are disposed at radial locations around the outer surface of the needle 22 that correspond to the radial spacing of the arms 135, 137 around the inner surface of the dilator 30.
The pairs of arms 135, 137 extend from the dilator 30 towards the needle 22. Each pair of arms 135, 137 is biased towards the needle 22 and is illustrated in a compressed or unlocked state in
In the illustrated embodiment, each arm of each pair of arms 135, 137 rotates towards the other arm between the unlocked position and the locked position. The arms 135, 137 need only be sufficiently biased so that when the arms 135, 137 align with the hole 139 their distal ends abut against a portion of the perimeter of the recess, opening, or hole 139. In the locked position, the distal ends of the arms 135, 137 are disposed within the recess, opening, or hole 139 in the needle 22.
The recess, opening, or hole 139 in the needle 22 locally increases a gap located between an outside surface of the needle 22 and an inside surface of the dilator 30 a sufficient amount to allow the arms 135, 137 to flex from their biased or unlocked state towards the locked position.
In the unlocked state Illustrated in
Each pair of arms 135, 137 can separately move to the locked position when the pair of arms 135, 137 is axially aligned with the recess, opening, or hole 139 in the needle 22. Once in the locked position, the size and shape of the pair of arms 135, 137 inhibit movement back to the unlocked position.
The locking mechanism 141 is illustrated on the dilator 30. However, the needle 22 may instead comprise the locking mechanism 141. In the illustrated embodiment, the needle 22 comprises a recess, opening, or hole 145 which interacts with the locking mechanism 141 of the dilator 30 when the needle 22 is sufficiently retracted into the dilator 30. The receptacle, recess, opening, or hole 145 may extend entirely around the needle 22 forming an annular groove or around only a portion of the needle 22. The needle 22 may comprise more than one recess, opening, or hole 145.
The protrusion 143 extends from the dilator 30 towards the needle 22 and is biased towards the needle 22.
The protrusion 143 need only be sufficiently biased so that when the protrusion 143 aligns with the hole 145 its distal end abuts against a portion of the perimeter of the recess, opening, or hole 145. In the locked position, the distal end of the protrusion 143 is disposed within the recess, opening, or hole 145 in the needle 22.
The recess, opening, or hole 145 in the needle 22 locally increases a gap located between an outside surface of the needle 22 and an inside surface of the dilator 30 a sufficient amount to allow the protrusion 143 to flex or extend from its biased or unlocked state towards the locked position.
In the unlocked state Illustrated in
The locking mechanism 147 is illustrated on the dilator 30. However, the needle 22 may instead comprise the locking mechanism 147. In the illustrated embodiment, the needle 22 comprises a recess, opening, or hole 151 which interacts with the locking mechanism 149 of the dilator 30 when the needle 22 is sufficiently retracted into the dilator 30. The receptacle, recess, opening, or hole 151 may extend entirely around the needle 22 forming an annular groove or around only a portion of the needle 22. The needle 22 may comprise more than one recess, opening, or hole 151.
The detent 149 extends from the dilator 30 towards the needle 22 and rides in an axial groove in the needle 22. The proximal end of the groove connects with the hole 151.
The recess, opening, or hole 151 in the needle 22 locally increases a gap located between a bottom surface of the groove in the needle 22 and an inside surface of the dilator 30 a sufficient amount to allow the detent 149 to flex or extend from a biased or unlocked state towards the locked position.
In the unlocked state illustrated in
The one or more fingers or tangs 162 inhibit the bevel tip 108 disposed on the distal portion 106 of the needle 22 from being advanced beyond the distal end of the dilator 30 once the dilator 30 has been advanced over the needle 22 during use. The dilator 30 thus sheaths the sharp bevel tip 108 of the needle 22 to inhibit accidental needle sticks from occurring.
The one or more fingers or tangs 162 may be integrated into the dilator hub 155 or part of a separate structure that is combined with the dilator hub 155. In the embodiment illustrated in
The dilator hub 155 and locking plate 157(a)-(c) may be separately manufactured and assembled as is illustrated in
The dilator hub 155 is similar to the dilator hub 32 illustrated in
A healthcare provider slides the locking plate 157(a)-(c) from an unlocked position to a locked position relative to the dilator hub 155. The locking plate 157(a)-(c) may be completely removed from the slot 158(a)-(c) or partially inserted into the slot 158(a)-(c) when in the unlocked position. When the locking plate 157(a)-(c) is in the locked position, the needle 22 is disposed in a hole or center region 160 of the locking plate 157(a)-(c). The small size of the guide wire 120 inside the needle 22 does not affect the locking feature of the assembly.
When in the locked position, at least one of the distal ends of the fingers or tangs 162 extends a sufficient distance toward the needle 22 to enter a hole or slot in the needle 22 and inhibit further axial movement of the needle 22. In some applications, the hole or slot in the needle 22 falls onto the finger or tang 162. The hole may be the one or more side openings 34 in the side wall of the needle 22 or the receptacle, recess, opening, or hole 131, 139, 145, and 151 illustrated in, for example,
Since the one or more fingers or tangs 162 do not extend entirely around the needle 22 when the needle 22 is inserted through the dilator hub 155, preferably the one or more side holes, receptacles, or annular groove in the needle 22 extend or are spaced radially about the needle 22 so that one of the fingers or tangs 162 will catch the one or more side holes, receptacles, or annular groove when the one or more side holes, receptacles, or annular groove passes through the locking plate 161.
In this embodiment, the locking plate 163 is inserted in the dilator hub 155 before the needle 22 is axially inserted into the dilator hub 155. Since the fingers or tangs 155 extend entirely around the needle 22, a sheath or mandrel temporarily covers the side hole in the needle 22 to allow the needle 22 to be assembled through the dilator hub 155. Once assembled, the sheath or mandrel is removed from the needle 22.
The slot 158(a)-(c) in the dilator hub 155 would include corresponding shaped surfaces which engage with the perimeter shape 165, 167, 169, 171 of the locking plate to inhibit the healthcare provider from removing the locking plate from the dilator hub 155 once the locking plate 157 has been slid to the locked position. In this way, the healthcare provider is prevented from accidently removing the locking plate and releasing the needle 22.
The embodiments herein described are comprised of conventional, biocompatible materials. For example, the needle preferably consists of a rigid polymer or a metal such as stainless steel, nitinol, or the like. The other elements can be formed of suitable polymeric materials, such as nylon, polyethylene, high-density polyethylene, polypropylene, fluoropolymers and copolymers such as perfluoro (ethylene-propylene) copolymer, polyurethane polymers or co-polymers.
As noted above, the present access device can be used to place a catheter at other locations within a patient's body. Thus, for example, but without limitation, the access device can be used with a variety of catheters to drain fluids from abscesses, to drain air from a pneumotorax, and to access the peritoneal cavity. In such applications, body fluids flow into the viewing space to indicate when the needle has been properly placed.
