A catheter connection system is defined by a rigid, tubular stem attached at a proximal end thereof to a medical device. The stem has a plurality of comparably configured engagement barbs encircling and radially, outwardly extending on an exterior surface of the stem. A locking barb also encircles and radially, outwardly extends on the surface of the stem between the medical device and the engagement barbs. A rigid first locking sleeve is provided for inwardly compressing a portion of a body wall of a silicone catheter against the locking barb on the stem when the stem is received in the lumen of the silicone catheter to create a mechanical joinder and liquid-tight seal between the silicone catheter and the stem. In the alternative, a compression sleeve housed within a rigid second locking sleeve is provided for compressing a body wall of a polyurethane catheter against the engagement barbs on the stem to create a mechanical joinder and liquid-tight seal between the polyurethane catheter and the stem.

A catheter connection system for effecting a mechanical joinder between a medical device and a selected catheter chosen from either a first catheter or a second catheter, the first catheter being made from a first material and the second catheter being made from a second material, the second material being less pliant than the first material, the selected catheter having a body wall with an exterior surface and with an interior surface defining a longitudinally extending, fluid flow lumen, said connection system comprising: (a) a rigid stem attached at a proximal end thereof to the medical device, said stem having a free distal end opposite said proximal end and an exterior surface extending therebetween; (b) attachment means on said exterior surface of said stem for engaging the interior surface of the selected catheter when said distal end of said stem is received in the lumen of the selected catheter, and for enabling locking of the selected catheter on said stem; and (c) securing means operative when said distal end of said stem is received in the lumen of the selected catheter for radially, inwardly compressing a portion of the body wall of the selected catheter against a portion of said attachment means on said stem, and for interacting with said attachment means to preclude unintentional disengagement of the selected catheter from said stem, said securing means comprising a set of fastening assemblies, individual of said fastening assemblies corresponding to the first catheter and the second catheter.
