Abstract: A vascular access device to passively open a fluid path within a vasculature. The vascular access device may include a catheter and a guidewire. The catheter may have a proximal end, a tip, and a length of tubing therebetween. The guidewire may extend along the length of tubing and may include a bent portion. At least a portion of the length of tubing may substantially conform to the bent portion such that the tip of the catheter avoids an obstruction within the vasculature.

Abstract: A guidewire delivery device may include a housing, which may include a distal end, a proximal end, a lumen extending through the distal end of the housing and the proximal end of the housing, and a slot disposed between the distal end of the housing and the proximal end of the housing. The tab may be moveable with respect to the slot. The guidewire delivery device may include a penetration cannula coupled to the tab and extending in a distal direction. The guidewire delivery device may include an adapter proximal to and in fluid communication with the penetration cannula.

Abstract: A blood draw system may include a catheter adapter connector in fluid communication with a catheter adapter, and a blood draw device in selective fluid communication with the catheter adapter connector. A first valve may be utilized to selectively permit fluid communication between the blood draw device and the catheter adapter connector. A flush device may also be in selective fluid communication with the catheter adapter connector to flush the catheter adapter after a blood draw procedure. A second valve may be utilized to selectively permit fluid communication between the flush device and the catheter adapter connector.

Abstract: A catheter system may include a catheter assembly, which may include a catheter adapter and a catheter extending distally from the catheter adapter. The catheter system may include a needle assembly, which may include a needle hub and an introducer needle extending distally from the needle hub. The introducer needle may extend through the catheter. The needle assembly may also include an extension tube, which may include a distal end integrated with the needle hub and a proximal end integrated with a cannula hub. A cannula may extend proximally from the cannula hub. An elastomeric sheath may be coupled to the cannula hub, and a proximal end of the cannula may be enveloped within the elastomeric sheath. In response to the blood collection tube pushing the elastomeric sheath distally, the cannula may pierce the elastomeric sheath, and the cannula may insert into the blood collection tube.

Abstract: A vascular access device adapter allowing for interchangeable connections between separate components of a larger extravascular system while minimizing exposure to non-sterile environments in point-of-care testing and analysis is provided. The vascular access device adapter includes a body having a self-healing puncturable septum secured by an end cap by which hollow small gauge needles may extract or deposit fluid. The adapter device further includes an end cap enclosing the septum, the end cap having ribs which removably secure the adapter to the inner housing of a sample collection device.
