Abstract
A double lumen flexible catheter for peritonetal dialysis comprises a double lumen structure with inner and outer tubes. The outer tube has a plurality of openings the inner tube being stretched in tension to prevent kinking of the catheter. The inner tube has a single outlet at the free end of the catheter. The tubing for the catheter is sufficiently flexible to permit the catheter to lie loosely and freely in the body cavity. Treatment fluids are delivered to the peritoneal cavity through the inner tube and removed via the outer tube.
