ABSTRACT:
A needle device for delivering medicaments to the body of a patient, the device including an elongated housing having a catheter on one end, with a trocar arranged through the end of the housing and the catheter. The trocar is reciprocably advancable and retractable with respect to the catheter. A spring biased carriage in the housing controls the movement of the trocar and causes it to retract from the distal end of the catheter after the catheter and trocar have been advanced into a body and the trocar no longer encounters resistance to forward or distally directed advance of the device.
