Abstract
An implantable catheter system includes an elongated hollow casing which is reinforced to maintain a predetermined attitude and made of a material penetrable by a needle, and a tube extending laterally of the casing so that when the casing is implanted subcutaneously in a person, the tube may extend into the person's peritoneal cavity. The tube is coupled into the casing to enable communication therebetween. The free end of the tube includes a plurality of openings to enable the flow of fluid therethrough into or out of the tube. When the catheter system is implanted in the body of a person, fluids may be introduced into and withdrawn from the peritoneal cavity by inserting a hypodermic needle through the epidermis of a person into the casing which is implanted subcutaneously in the person. Fluid is then injected into or withdrawn from the casing to thereby respectively force fluid through the tube into the peritoneal cavity or withdraw fluid from the cavity via the tube.
