  • Patent number: 8348899
    Abstract: Catheter assembly (100) having at least one lumen (150 or 160) and joined to hub (106). While the lumen inner diameter(s) remain constant from distal end (144) of the catheter (140) to proximal end (142), the outer catheter diameter increases proximate the hub (106) providing increased resistance to kinking during connection and disconnection from medical apparatus. The increased proximal catheter diameter preferably is sufficiently large to plug the proximal end of an introducer sheath through which the catheter is inserted during patient placement, to plug the proximal sheath end and minimize blood aspiration therethrough, and later serves to fill the vascular insertion upon complete catheter insertion after removal of the introducer sheath again to minimize blood aspiration through the vascular incision. The catheter may have two lumens (150,160) or more, joined to respective extension tubes in hub (106). The two lumens may each have a respective inner diameter of between about 0.020 in and 0.025 in.

  • Patent number: 7972313
    Abstract: A safety IV catheter includes a unitary, resilient needle guard received in a catheter hub. The needle guard includes a proximal arm or wall that includes an opening through which a needle passes for axial movement. When the needle is retracted from the catheter, it releases the force that had previously prevented movement of the needle guard within the catheter hub. This in turn causes the needle guard to snap into a position in which it is clamped onto the needle shaft and in which its distal wall blocks access to the needle tip. In this condition, the spring needle guard and needle can be removed from the catheter hub. A slot or crimp may be formed in the needle shaft that engages with the needle guard after the protected needle and needle guard are removed from the catheter hub, thereby to prevent removal of the protected needle from the needle guard.

  • Patent number: 6989003
    Abstract: A surgical trocar device having an obturator and cannula that requires less force to insert and remove from tissue. The cannula includes a head assembly and the obturator includes a cap assembly that have cooperating surfaces that bear against each other so that when the obturator is rotated about its axis the obturator is axially deflected within the cannula and thus more easily removed from the tissue into which the obturator is inserted. The tip of the obturator and the end of the cannula are designed to minimize tissue damage and insertion effort by providing a smooth, unencumbered surface transition. In one aspect of the invention, the tip of the cannula is smooth, continuous, and flexible and can radially deflect when the larger-diameter obturator is inserted or withdrawn though the cannula.

  • Patent number: 6852290
    Abstract: A multi-well assembly according to one embodiment comprises a multi-well block and a guide plate. The multi-well block defines a plurality of wells, with each well having a fluid-impermeable bottom surface. The guide plate defines a plurality of fluid passageways corresponding to the wells of the multi-well block. The guide plate is configured such that, whenever the guide plate is registered with the multi-well block, fluid communication is established between each well and an associated fluid passageway.

  • Publication number: 20040260243
    Abstract: A connection system for connecting a hemostasis valve to a splittable sheath is disclosed. The connection system includes an adapter fitting having a shaft defining a lumen. The shaft has a proximal end and a distal end. On an external surface of the proximal end of the shaft, threading is provided for engagement with the hemostasis valve. A cannula portion defines the distal end of the shaft for interfacing with a splittable sheath. A wedge is disposed on an external surface of the cannula portion for interfacing with a weakened portion of the splittable sheath. A sliding connector is disposed about the shaft for engagement with the splittable sheath. Upon a first level of engagement between the sliding connector and the splittable sheath, a fluid-tight seal is created. Upon a second level of engagement between the sliding connector and the splittable sheath, the wedge initiates separation of the splittable sheath.

  • Patent number: 6692465
    Abstract: An intravascular catheter system, such as a dilatation catheter system for angioplasty procedures, which provides for the replacement of the catheter or the guidewire during the procedure. The intravascular catheter has a guidewire-receiving inner lumen extending along its length. A first guidewire port is provided in the catheter body at or near the proximal end of the catheter. A second guidewire port is provided in the catheter body at a location spaced distally from the first guidewire port and proximally from a diagnostic or therapeutic tool, such as a dilatation balloon, on a distal portion of the catheter. A third guidewire port is provided in the distal end of the catheter. The guidewire ports are in communication with the guidewire-receiving inner lumen.

  • Patent number: 6673101
    Abstract: An assembly for delivering a stent to an intraluminal location comprising a catheter having an inner member and an outer member, a stent positioned between the inner member and the outer member at the catheter distal end, and a cutter/slider/deployment mechanism slidable secured to the catheter proximal end. A user may vary the length of the catheter by slidably advancing the cutter/slider/deployment mechanism along the catheter, whereby excess portions of the catheter are cut away. When the desired length is achieved, the user can secure the cutter/slider/deployment mechanism to the catheter to prevent further slidable advancement. The user may also vary the configuration of the catheter handle by adding or removing a removable platform from the handle. Upon stent deployment, the stent is released from the outer member, and the stent will expand as desired.

  • Publication number: 20030199826
    Abstract: The present invention relates to a multi-size catheter for use in biliary endoscopic procedures. The multi-size catheter comprises an outer diameter defined by a plurality of superimposed peelable layers. The peelable layers allow the multi-size catheter to function as a single operator exchange catheter without the need, and additional expense, of an endoscope sheath. Before positioning the multi-size catheter within the working channel of an endoscope, the peelable layers may be selectively removed in order to obtain an outer diameter for the catheter that is less than, but approximate to, the inner diameter of the working channel of the endoscope. The resulting fit eliminates the potential for a guidewire to slip out of the guidewire channel and become pinched between the catheter and the endoscope working channel. With an incorrect fit, a pinched guidewire would restrict the desired movements of both the guidewire and the catheter.

  • Patent number: 6579267
    Abstract: System for the subcutaneous delivery into the body of a patient of a fluid from a remote vessel. The system includes a main assembly and placement member with a needle. A delivery tube for carrying the fluid is attached at a near end to the remote reservoir or vessel. At removed end, the delivery tube has a needle for engagement with the main assembly. The main assembly includes a rotating member that when the rotating is perpendicular to the main assembly, it will accept the handle and needle for emplacement of the body onto a patient. After the handle and needle are removed, the delivery tube can be attached to the rotating member which can then be rotated down to a position along to and adjacent the skin of the patient. This provides for a flush mounted infusion device.
