A catheter system for locking a catheter to an implantable pump and for effectively flushing a catheter after implantation within a body. A locking component comprises an extension boot and catheter lock that together fluidly connect the catheter to the pump in a secure, safe and effective manner. A catheter component comprises a design having kink-resistant walls and a unique tip. A flushing component comprises a hub and stylet combination characterized by a hydrophilic coating on the stylet and a flush through hub to allow flushing of the stylet while inside the catheter.

Implantable pump connector for catheter attachment

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 engagement barbs encircling and radially, outwardly extending on an exterior surface of the stem. The engagement barbs can be configured having a variety of different sizes and positions. A locking barb also encircles and radially, outwardly extends on the surface of the stem between the medical device and the engagement barbs. A variety of fastening assemblies are provided for inwardly compressing a portion of a body wall of a selected catheter against the engagement barbs on the stem, when the stem is received in the lumen of the selected catheter. The fastening assemblies create a mechanical joinder and liquid-tight seal between the selected catheter and the stem. The selected catheter can be chosen from one of three or more catheters each having a combination of size and material composition distinct from the other of the catheters.

Multiple-type catheter connection systems

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.
