Abstract
An implantable catheter for subcutaneous placement defining a tubular member which carries an enlarged, hollow, needle-pierceable member on one end thereof. The enlarged hollow member is implanted under the skin. The catheter defines a pair of angled turns, each of the angled turns occupying a plane which defines approximately a 90 degree angle to the plane of the other angle. This permits the enlarged portion of the catheter to be horizontally positioned subcutaneously, relative to an erect patient, while the end of the tubular catheter extends to its desired location in the peritoneal cavity.
