Abstract

A catheter connection system and a method of connecting the catheter connection system to a catheter. The catheter connection system includes a hub assembly and a collar. The hub assembly includes a cannula extending from a distal end thereof, and a collet defining an inner surface spaced apart from the cannula to permit passage of a catheter wall between the body and the cannula. The collet includes a proximal barb on an outer surface and the collar includes an attachment barb on an inner surface, engagement of the respective barbs acting to provide a permanent connection between the collar on the collet, while permitting free rotation of the collar about the collet.
