Abstract

A kink resistant multi-purpose drainage catheter. A drainage catheter is constructed using kink resistant tubing. One end of the kink resistant tube forms a drain for bodily fluids. The opposite end of the kink resistant tube has a molded LUER connector. The drain has numerous holes along its length to allow drainage. The substrate of the kink resistant tube is constructed from an extrusion. The extrusion is then covered with a coil along the body of the catheter. The entire length of the drainage catheter is coated with a final layer of polyurethane. The drain may be formed in a number of desired shapes along with the position of drainage holes.
