ABSTRACT:
A trocar and catheter assembly for automatically disarming the trocar after placement of the catheter into a patient's blood vessel includes a spring urging retraction of the trocar and a releasable retainer mechanism for maintaining the trocar in an extended position during insertion of the catheter into the blood vessel. The catheter is removably mounted to a handle which defines an internal passage. Disengaging the handle from the catheter after placement of the catheter into the blood vessel actuates the releasable retainer mechanism for allowing the trocar to be drawn into the handle passage under the influence of a spring, to enclose the sharpened end of the trocar after use.
