An extravascular system is provided which includes a catheter adapter having a blood control septum configured to control flow of a fluid through the catheter adapter, the catheter adapter further having a catheter configured for intravenous insertion. The extravascular system further includes a septum activator slidably inserted within the catheter adapter and configured for advancement through the blood control septum to provide a fluid pathway through the blood control septum. Further still, the extravascular system includes an external safety mechanism comprising a needle hub and a needle shield interconnected via a tether, wherein the needle shield includes a safety clip that is configured to retain a sharpened end of the introducer needle within the needle shield. Some implementations further comprise an access port forming a portion of the catheter adapter and providing selective access to the lumen of the catheter adapter.

A hemostasis valve assembly for use in a medical device. The hemostasis valve assembly may include a main body portion defining an internal cavity, a seal cartridge disposed within the internal cavity, and a low pressure valve assembly positioned within the internal cavity adjacent to the seal cartridge. The low pressure valve assembly may include a first valve member having a first valve body and a second valve member having second valve body. A portion of a distal side of the first valve member may abut at least a portion of a proximal side of the second valve member.

Disclosed herein is a system for treatment including a sheath introducer and a catheter or other device. The system can have a floating hemostasis valve comprising a seal through which the shaft of the catheter can extend. The floating hemostasis valve can have elastic bellows which can allow the seal to move orthogonal to the longitudinal axis of the sheath introducer in response to an orthogonal movement of the shaft of the catheter. The elastic bellows can be configured to deform to allow the orthogonal movement of the floating hemostasis valve.

The present invention relates to a multiple-use intravenous (IV) catheter assembly septum and septum actuator. In particular, the present invention relates to an IV catheter assembly having a stationary septum actuator and a blood control septum, wherein the blood control septum is configured to slide within a catheter adapter of the IV catheter assembly between a compressed state and an uncompressed state. When in the compressed state, a slit of the blood control septum is opened and the septum comprises stored compressive potential energy. When the septum is released from the compressed state, the stored compressive potential energy is release and the blood control septum is restored to its original shape, thereby closing the septum's slit.

A hemostasis valve for use with catheters in intravascular procedures. The hemostasis valve comprising a sealable fluid channel that bifurcates from a single distal lumen to two proximal lumens. An upper proximal lumen may include a funnel shaped opening to improve aspiration potential. Rotating locking mechanisms are attachable at the ends of the hemostasis valve to interlock coaxial devices or to form seals around coaxial devices. Injection molding may be used to manufacture a hemostasis valve and its components. A mold and core pins may impart external and internal shapes to a molten polymer. Once the polymer has cooled, the molded component is separated from any pins or molds and attached to other molded components to form an assembled hemostasis valve.

An introducer assembly is adapted for deploying a medical device. The introducer assembly includes an introducer body that is adapted to accommodate a volume of blood therein. An antechamber is coupled with the introducer body. A first hemostasis valve is disposed proximal of the antechamber and fluidly couples the introducer body with the antechamber. A second hemostasis valve is disposed distal of the antechamber and is adapted to allow the medical device to pass therethrough.

A urological device includes a valve retained in a urinary catheter. The urinary catheter has a first portion that is insertable into a urethra and a second portion adapted to remain outside of the urethra when the first portion is inserted into the urethra. The valve has a closed configuration adapted to prevent urine from exiting the urinary catheter and an open configuration adapted to allow urine to flow through and exit the urinary catheter. The valve is adapted to move from the closed configuration to the open configuration in response to a hydrodynamic pressure of at least 750 mm H2O applied to the valve for at least 5 seconds.

A valve for sealing the hub of a sheath assembly is provided. The valve includes a valve body having a solid thickness extending between a proximal surface and a distal surface. A bisecting slot extends across the proximal surface of the valve body and terminates at a depth less than the thickness of the valve body such that a portion of the valve body distally of the slot defines a bridge extending between opposed halves of the valve body such that the distal surface of the valve body is substantially continuous and a central portion of the proximal surface of the valve body is concave and defines a concave proximal portion.

An introducer hub assembly, such as an introducer hub assembly of a leadless cardiac pacemaker, including a hemostatic seal having a cross-slit configuration, is described. The hemostatic seal can be retained between a hub cap and an introducer hub. The hemostatic seal includes a first section having first slits intersecting along a longitudinal axis of the introducer hub, and a second section having second slits intersecting along the longitudinal axis. The first slits are angularly offset relative to the second slits to reduce a likelihood that fluid will leak directly through the seal. Other embodiments are also described and claimed.

A vascular access system which may be configured for blood draw may include a housing, which may include a distal end, a proximal end, and a slot disposed between the distal end and the proximal end. The slot may include a notch. The vascular access system may include a cannula hub, which may be disposed within the housing and movable with respect to the slot. The cannula hub may include a tab extending through the slot. The vascular access system may include a cannula extending distally from the cannula hub. In response to the tab being disposed within the notch, a distal tip of the cannula may be disposed within the housing. In response to advancing the tab along the slot to a distal end of the slot, the distal tip of the cannula is disposed distal to the distal end of the housing.
