Vascular access catheters that include a catheter body having one or a plurality of lumens longitudinally extending therethrough. The lumens have cross-sectional shapes that enhance kink resistance, support reliable slit valve operation, and couple securely with the outlet stem of a multiple reservoir implantable access port. In a dual lumen catheter disclosed, each of the lumens are defined by a plurality of longitudinally extending generally linear inner wall surfaces. The inner wall surfaces when viewed in a transverse cross section of the catheter body taken normal to the longitudinal access have trapezoidal shapes. Other cross-sectional shapes are also illustrated. A generally planar septum separates the pair of lumens. The lumens effect a fluid-tight mechanical engagement between the D-shaped outlet prongs of a conventional outlet stem of an implantable dual reservoir access port, highly reliable two-way, three-position slit valves may be associated with each of the lumens. The valve for each lumen has a closed position thereof in which fluid communication is precluded between the lumen and the exterior of the catheter body, but the valve is selectively operable under the influence of appropriate pressure differentials between the lumens and the exterior of the catheter from the closed position into either an inwardly or an outwardly open position.

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 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 method and apparatus for locating the injection point of an implanted medical device. In a preferred embodiment, the locating apparatus is in the form of radiopaque rings made of a metallic substance. When these rings are spaced apart at different heights on an implanted medical device, such as a drug port, a stereoscopic effect results from fluoroscopically viewing the device along an axis not parallel to the axis along which the rings are spaced. This effect allows one to readily determine the orientation of the device. This prevents accidental injection of drugs into the hard backside of the drug port.
