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.
A catheter connection system for effecting a mechanical joinder between a medical device and a selected catheter chosen from among a first catheter, a second catheter, and a third catheter, the first catheter being made from a first material, the second catheter and the third catheter being made of a second material less pliant than the first material, and the inner diameter of the third catheter being smaller than the inner diameter of the second catheter, 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 catheter connection system for effecting a fluid tight coupling and a mechanical joinder between a medical device that accommodates for the flow of fluid therethrough in two distinct fluid flow pathways and a selected dual lumen catheter the selected dual lumen catheter having a body wall with an exterior surface and an interior surface, a catheter partition wall extends between spaced locations on the interior surface to define two distinct longitudinally extending, fluid flow lumens within the body wall, said connection system comprising:
A catheter conversion system for effecting a fluid tight coupling and a mechanical joinder between a selected dual lumen catheter and two distinct selected single lumen catheters, the selected dual lumen catheter being chosen from among two or more dual lumen catheters each having a unique combination of size and material composition distinct from the others of the dual lumen catheters, the selected dual lumen catheter having a body wall with an exterior surface and an interior surface, the dual lumen catheter further having a partition wall extending between spaced locations on the interior surface to define two distinct longitudinally extending, fluid flow lumens within the body wall, each of the selected single lumen catheters being chosen from among two or more catheters each having a combination of size and material composition distinct from the other of the catheters, each of the selected single lumen catheters having a body wall with an exterior surface and with an interior surface defining a longitudinally extending, fluid flow lumen, said catheter conversion system comprising:
