PERCUTANEOUS IMPLANT FOR PERITONEAL DIALYSIS

摘要

IMPROVED PERCUTANEOUS IMPLANT FOR PERITONEAL DIALYSIS An implant device for peritoneal dialysis which permits a flexible catheter to be removed and replaced without invasive surgery. The catheter is passed through a substantially rigid tubular percutaneous device and a flexible sleeve member which together form a continuous conduit from the body exterior through the peritoneal wall. The catheter is associated with a percutaneous tubular device so as to be removable and replaceable through the sleeve member after implantation. The catheter preferably has a relatively weak memory which gives it a tendency to maintain a compact coiled configuration near the peritoneal wall. The catheter may extend through the percutaneous device or; more preferably; terminates within the interior cavity of the percutaneous device and is sealed from the environment by means of a septum closure within the device cavity.
