ABSTRACT:
A novel implantable, peritoneal injection catheter apparatus and method, the apparatus including an enlarged target surface, fluid-receiving reservoir mounted to one end of a hollow stem. The hollow stem is configured to extend into the peritoneal cavity and includes a retaining ring system for retaining the hollow stem in relationship to the peritoneal cavity. A penetrable membrane covers the enlarged target surface of the receiving reservoir and serves as an injection site for inserting a hollow needle into the receiving reservoir. A substantial portion of the injection catheter is covered with a velour coating to accommodate tissue ingrowth and further securement of the catheter in the tissue of the abdominal wall.
