Obturator to Facilitate Catheter Line Draw

Abstract:

A vascular access device to passively open a fluid path within a vasculature. The vascular access device may include a catheter and an obturator slidably positioned within the lumen of the catheter. The catheter may have a proximal end, a distal tip comprising an opening having an inner diameter, a sidewall defining a lumen between the proximal end and distal tip. The obturator may have a distal end with an outer diameter configured to form an interference fit with the inner diameter of the distal tip. The obturator may be positioned within the lumen to open various fluid pathways. The obturator may be repositioned to move the catheter tip.
