Abstract

A catheter connection system is described herein, including a hub assembly and a connector assembly, the hub assembly including a cannula configured for insertion into a catheter lumen and the connector assembly including a collet and collar. The collet is connected to the hub assembly and positioned about a distal portion of the cannula such that an inner surface of the collet is spaced from an outer surface of the cannula. The collar and collet include features that interact with one another to provide a locking engagement. Also described is a multifunction adaptor to establish a connection between a catheter and another instrument, such as a tunneler or syringe.
