ABSTRACT:
A method of making a self-capping needle and catheter assembly (10) includes placing a needle hub (16) and cap (34) on a pin with the pin extending through the passageways (24, 35) thereof. Two sheets of polymeric material (62) are placed about the hub (16) and the cap (34) with their edges welded together producing a sleeve (64) connected between the hub (16) and the cap (34). The sleeve (64) is then permanently stretched to a predetermined length. The cap (34), hub (16) and sleeve (64) are then placed on a needle (28) and the cap (34) is moved against the hub (16) folding the sleeve (64) therebetween for reception of the catheter assembly (14).
