ABSTRACT:
An implant device for introduction of insulin into the peritoneal cavity which permits a flexible catheter to be removed and replaced without invasive surgery. The catheter is passed through a substantially rigid percutaneous body and a distally extending catheter conduit which together form a continuous conduit from the body exterior through the peritoneal wall. A polytetrafluoroethylene polymer sleeve allows tissue ingrowth to secure the body to the epidermis. A polyethylene terephthalate portion of the sleeve provides tissue ingrowth to stabilize the implant and prevent extrusion from the dermis. The catheter is associated with the percutaneous tubular body so as to be removable and replaceable through the conduit thereformed after implantation. The catheter preferably terminates within the interior cavity of the percutaneous body and is sealed from the environment by means of a septum closure within the device cavity. A sponge saturated with antiseptic is fitted in the body recess above the septum and is closed off from the environment by a penetrable cap member. The saturated sponge prevents the introduction of bacteria into the peritoneum.
