  • Patent number: 12201800
    Abstract: An extension set may include a tube having an outer surface. An instrument, such as a tubing or a probe, may be disposed within the tube and may include a proximal end and a distal end. A translation handle may be coupled to the outer surface of the tube and may move along the outer surface between a proximal position and a distal position to translate the distal end of the instrument between a retracted position and an advanced position. In the advanced position, the distal end of the instrument may extend beyond the distal end of the tube and into a catheter assembly and/or vasculature of a patient.

  • Patent number: 12186501
    Abstract: An introducer needle may include a proximal end, a distal tip, and a needle lumen extending therebetween. The introducer needle may include a wall defining the needle lumen, a first notch formed through the wall, and a second notch formed through the wall. A catheter system may include a catheter adapter, a catheter extending distally from the distal end of the catheter adapter, a flash chamber coupled to the introducer needle, and the introducer needle, which may extend through the catheter. The first and second notches and the flash chamber may facilitate pressure-driven blood flow into the catheter for improved flashback and detection of transfixation when the catheter is primed prior to insertion into vasculature of a patient or otherwise.

  • Patent number: 12171970
    Abstract: A vascular access device including a catheter adapter, a port opening, and an elastomeric valve. The catheter adapter extends along a longitudinal axis and includes a proximal end, a distal end, and a lumen extending therebetween. The port opening is formed in a surface of the catheter adapter in fluid communication with a side port of the catheter adapter and the lumen. A structural geometry of the port opening directs a fluid into the lumen in a proximal direction. The elastomeric port valve is disposed within the lumen and configured to deform in response to a transverse force applied thereto. A proximal gap may result between the inner wall forming the lumen and a proximal side of the elastomeric port valve, thereby opening a fluid path.
