Catheter with wire stylet

摘要

A catheter introducer device using a silicone rubber catheter with a stylet therein permitting introduction by manual threading of catheters which would otherwise be too flexible for individual insertion. The stylet is held at its proximal end by a hub which, with a seating ferrule, abuts a proximal end of the catheter. The hub may be pushed to wedge the catheter in an introducer cannula and is then withdrawn carrying the stylet with it, leaving the catheter in place and ready for use.
