Abstract

A catheter insertion device (10) has a stylet (12) with a needle (14) extending therefrom. A catheter (16) has a cannula (20) surrounding he needle (14) and a connection hub (22) supported upon an alignment member (24) at the front of the stylet (12). A spring (44) exerts a earward force upon the needle (14). A needle retaining member (14) having a releasable latch mechanism is positioned within the stylet 12) for counteracting the rearward force of the spring (44) and holding the needle in the extended position. After insertion of the catheter 16) within a blood vessel of a patient, a predetermined force is applied to an actuating member (64) protruding from the rear of the stylet 12). The actuating member (64) releases the latch mechanism, and the needle (44) is propelled by the spring (44) to be permanently etained within an internal cavity (72) of the stylet (12).
