A low-profile universal passive protector for an IV catheter includes a connector having a tubular body and a pair of arms pivotally connected thereto. The tubular body defines an end face and the connector includes a cavity extending from the end face. An elongate sheath is snap engageable to the tubular body. A spring is insertable within the connector cavity to extend between at least one of the pair of arms and the elongate sheath when received within the cavity. A slider is moveably coupled to the sheath. The slider includes a flashback chamber formed therein. A hypodermic needle is connected to the slider and is in fluid communication with the flashback chamber. The slider is moveable along the sheath between a first position and a second position, with the hypodermic needle being drawn into the sheath as the slider moves from the first position toward the second position.

A passive safety catheter assembly configured to inhibit access to the distal tip of a needle cannula prior to release of a catheter insertion assembly from a catheter hub. The passive safety catheter assembly includes a safety clip assembly configured to transition between a first position in which the safety clip assembly selectively couples the catheter insertion assembly to the catheter hub, and a second position in which the safety clip assembly traps the sharp distal tip of the needle cannula within the safety clip assembly prior to release of the coupling between the catheter insertion assembly and the catheter hub.

Needle guards that can be made from a combination of plastic and metal can be used with sharp medical devices. The needle guard can have a proximal wall defining a distal surface, a proximal surface, and a through opening, the proximal wall being made of a first material. The needle guard can have a first resilient arm extending distally from the distal surface of the proximal wall, the first resilient arm comprising an arm section and a distal wall. The needle guard can have a second resilient arm extending distally from the distal surface of the proximal wall, the second resilient arm comprising an arm section and a distal wall. One of the first resilient arm and the second resilient arm can be made of a second material different from the first material of the proximal wall.

Valve assemblies having improved ability to selectively control flow of fluids through the catheter and prevent leakage of fluids from the proximal end of a catheter that is positioned within a patient. Such improved catheter valve assemblies also prevent leakage of fluids after repeated insertion and removal of medical instruments through the valve.

An intravenous (IV) catheter system may include a catheter hub, a needle hub and a needle shield. The needle hub may include a needle having a high friction surface part. Furthermore, embodiments may include an open and closed IV catheter system. Embodiments may include a needle hub and a shielded needle system.

A safety needle device is disclosed having a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body. A needle hub is disposed on the proximal end of the housing and a needle cannula is attached to the needle hub. The device having a retractable sheath configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula. The safety needle device may include an activation latch, a lockout latch, a tether and a spring element to bias the retractable sheath to an extended state to cover the distal end of the needle cannula upon completion of an injection. The safety needle device may include a slider element disposed above an activation latch. A method of drug delivery is also disclosed.

A tool (10) for inserting a catheter (22) into a body of a patient is provided. The tool (10) comprises: a housing (12, 40, 50) in which at least a portion of the catheter (22) is initially disposed; a needle (16) distally extending from the housing (12, 40, 50), at least a portion of the catheter (22) disposed over the needle (16); a guidewire (32) initially disposed within the needle (16) partially; and an advancement assembly (20) for distally advancing the catheter (22). The housing (12, 40, 50) comprises: a first portion (12A, 42, 52) comprising a distal part (42A, 52A) and a proximal part (42B); and a second portion (12B, 44, 54) engaged with the first portion (12A, 42, 52), wherein the distal part (42A, 52A) of the first portion (12A, 42, 52) is configured to be able to distally slide with respect to the second portion (12B, 44, 54) to release the engagement between the first portion (12A, 42, 52) and the second portion (12B, 44, 54). The advancement assembly (20) includes a safety cap (26) which is initially disposed over the needle (16) and is configured to be locked to the housing (12, 40, 50) when distally sliding to a position of isolating the tip of the needle (16) within the safety cap (26).

A connector to secure a winged needle set to a catheter assembly may include a male luer lock. The male luer lock may include a tapered male discharge nozzle and a locking ring surrounding the tapered male discharge nozzle. The locking ring may be internally threaded. The connector may include a septum configured to prevent flow through the tapered male discharge nozzle. The connector may include an arm, which may include a first end, a second end, and a hinge portion disposed between the first end and the second end. The first end may be coupled to the male luer lock. In response to the hinge portion moving from an open position to a closed position, the arm may be configured to secure the winged needle set to the connector.

A catheter system may include a needle assembly coupled to a catheter adapter. The needle assembly may include a housing, an introducer needle, a distal opening, a first magnet, and a second magnet. In response to proximal withdrawal of the introducer needle, the first magnet may move towards the second magnet, which may block the distal opening and/or prevent blood from leaking out the distal opening.

Needle assemblies and related methods having a needle hub with a needle, a catheter tube with a catheter hub and having the needle extending through the catheter tube, a valve positioned in an interior cavity of the catheter hub, a valve opener proximal of the valve, and a needle guard extending at least partially into the valve opener. The valve opener can be used with a range of needle sizes. The valve opener can be used for forming a sub-assembly while minimizing distortion or compression of a needle guard.
