Abstract
A vascular access system may include a catheter assembly, which may include a catheter hub and a catheter extending distally from the catheter hub. The vascular access system may include an instrument advancement device coupled to the catheter assembly. The instrument advancement device may include a vascular access instrument. The vascular access instrument may include a coil formed by a flat wire wound around an axis into multiple loops. The instrument advancement device may be configured to advance the vascular access instrument from a retracted position to an advanced position beyond a distal end of the catheter. The distal end of the catheter may include a distal opening. The coil may extend through the distal opening of the catheter in response to the vascular access instrument being in the advanced position.
