Abstract: Devices and methods for an autovance intraosseous device. The autovance intraosseous device can include a trigger activated system or pressure activated system that causes a needle to advance distally for a predetermined distance. The predetermined distance ensures a needle tip extends through the bone cortex, to access the medullary cavity, without penetrating a far wall of the medullary cavity. The advancement can be driven by a spring based system or an electric motor.

Abstract: Catheter placement assemblies having automatic guidewire disengagement can include a handle and seal housing assembly defining a needle lumen and guidewire lumen. Once the vasculature is accessed, the guidewire advances through the handle guidewire lumen to a target location. The needle is withdrawn proximally through the handle needle lumen with a first force. When the needle tip is withdrawn into the seal housing, the seal housing locks to the needle tip. Applying a second, greater force urges the seal housing to disengage the handle. The seal housing is retained in place by a detent and/or timing lock mechanism. As the seal housing is urged proximally, a support pin retains the guidewire in place causing the guidewire to automatically disengage the seal housing. The seal housing mitigates needle stick injuries and allows the needle and seal housing assembly to be removed, allowing for unobstructed advancement of the catheter over the guidewire.

Abstract: A RICC insertion assembly can include a RICC, an introducer needle, and a coupler coupling the RICC and the introducer needle together. The introducer needle can include a needle hub over a proximal portion of a composite shaft including a sheath over a needle shaft sealing a needle slot of the needle shaft thereunder. The coupler can include a coupler housing and a valve module disposed in the coupler housing. The composite shaft can pass through an introducer-needle passageway defined by a valve-module housing of the valve module such that the valve module forms a seal over a sheath opening of the sheath in a ready-to-deploy state of the RICC insertion assembly. The valve module can include a needle-stick-injury protection mechanism configured to capture a distal needle tip of the needle shaft within the valve module when the introducer needle is withdrawn from the coupler in a proximal direction.

Abstract: Rapidly insertable central-catheter (“RICC”) insertion assemblies and associated methods include valve modules. For example, a RICC insertion assembly can include a RICC, an introducer needle, and an access guidewire coupled together by a coupler in which a valve module is disposed. The introducer needle includes a needle shaft having a longitudinal needle slot and a sheath over the needle shaft sealing the needle slot thereunder except for that under a sheath opening of the sheath. The valve module includes an elastomeric gasket encircling at least a portion of a valve-module compartment of the coupler housing. In a ready-to-deploy state of the RICC insertion assembly, the gasket is compressed in the valve-module compartment around both the introducer needle and the access guidewire where the access guidewire extends from the sheath opening, thereby creating a substantially air-tight space within the gasket around the introducer needle and the access guidewire.

Abstract: An intraosseous access device can include a constant-torque spring assembly disposed in a housing, a drive shaft extending from the housing, and an intraosseous needle coupled to the drive shaft configured to provide intraosseous access to a medullary cavity of a patient. A method of using an intraosseous access device can include inserting a distal end of the intraosseous needle through skin at an insertion site of a patient and applying a contacting force to a bone beneath the insertion site with the distal end of the intraosseous needle. The contacting force can initiate a winding of a metal ribbon of the constant-torque spring assembly from an output spool onto a storage spool, thereby initiating drilling rotation of the intraosseous needle. The method can further include drilling through the bone until the intraosseous needle enters a medullary cavity of the patient.

Abstract: A catheter containment device configured to retain a proximal portion of a catheter placement system, such as a catheter, hub, extension leg, luer lock, or guidewire. The device includes a handle configured to engage a digit of the clinician to couple the device and the proximal portion of a catheter placement system thereto. This allows the clinician to retain the proximal portion within the sterile field without reducing dexterity or obstructing the clinician's view of the insertion site or the catheter placement system. Further the device can allow the clinician to manipulate the proximal portion of the catheter system while mitigating dropping or tangling.

Abstract: A catheter containment system configured for securing a proximal portion of a catheter placement system within a sterile field. This relieves the clinician from holding the proximal portion to prevent them for falling outside of the sterile field. Further, the proximal portion can be secured out of the way from the insertion site providing a clear field of view. Embodiments include a body, having a channel configured to releasably engage an extension leg or guidewire, and a securement feature to secure the body to a portion of a drape or similar item of the sterile field. Exemplary securement features can include clips, clasps, pins, magnetic elements, adhesives, twist ties, zip ties, snap fasteners, hook and loop attachments, mechanical grasping devices or adhesive pads. The system can further include anchor tabs that can be adhered to the drape to provide an anchor point.

Abstract: Constant-torque intraosseous access devices and methods thereof are disclosed. An intraosseous access device can include a constant-torque spring assembly disposed in a housing, a drive shaft extending from the housing, and an intraosseous needle coupled to the drive shaft configured to provide intraosseous access to a medullary cavity of a patient. A method of such an intraosseous access device can include inserting a distal end of the intraosseous needle through skin at an insertion site of a patient; applying force to bone at the insertion site with the distal end of the intraosseous needle, which starts winding a metal ribbon of the constant-torque spring assembly from an output spool onto a storage spool, thereby starting rotation of the intraosseous needle; and drilling through the bone until the intraosseous needle enters a medullary cavity of the patient, thereby achieving intraosseous access with the intraosseous access device.

Abstract: Introducer needles can be used with rapidly insertable central catheters (“RICCs”) or even other central venous catheters (“CVCs”). An introducer needle can include a needle shaft, a sheath, and a needle hub.

Abstract: Embodiments of catheter placement systems described herein include a temporary splittable sheath anchor, disposed on an outer surface of a needle. The splittable anchor moves with respect to the needle when accessing the vessel, allowing for a temporary anchor to be created as soon as venous access is confirmed via flashback. The clinician can advance the anchor over the needle once vessel access has been confirmed by flashback. The needle can then be removed without further insertion into the vessel, mitigating accidental trauma. The guidewire can then be introduced through the anchor and advanced to a target location within the vasculature. The anchor can then be removed by splitting and withdrawing the anchor proximally. Embodiments further include a splittable advancement sheath including a guidewire and configured to be drawn thorough a housing and split to allow the guidewire to separate from the advancement sheath and advance into the vasculature.

Abstract: A needle for accessing a vasculature of a patient is disclosed. The cannula of the needle includes a fluid lumen extending from the distal end to the proximal end and a guideway lumen extending proximally away from the distal end. The guideway lumen is configured for placement of a guidewire therein, and the guideway lumen includes a guideway slot extending along a length of the guideway lumen, where the guideway slot extends radially through a guideway-lumen wall and extends along the guideway lumen to the distal end. Also disclosed is a sheath covering the cannula and the sheath includes a separable portion through which guidewire may laterally pass. Also disclosed is a collar rotatably positionable between a guidewire secure position and a guidewire release position.

Abstract: Embodiments disclosed herein are directed to catheter placement systems including distally extendable support devices. When placing elongate catheters advanced insertion systems are required to maintain a “touch-free” insertion. Further longer needles are desirable to access deeper veins or penetrate deeper surface tissues. Distally extendable support devices provide columnar support to one of the elongate catheter or the needle to prevent buckling or kinking of the catheter, and maintain the needle tip within a predetermined bending arm distance. This prevents the user from contacting one of the needle or the catheter directly to provide additional support, maintaining a “touch-free” insertion.
