Abstract
Extra- to intra-corporeal power is provided by a transformer implanted at least partially within a defunctionalized intestinal pouch (or sack), such as an ileal pouch. The transformer includes a continuous loop magnetic core which is implanted within the pouch. The pouch itself includes a passageway permitting the secondary wiring to extend around the and through the magnetic core and through its central opening without entering the pouch providing intracorporeal current. Wire providing the primary windings extend from outside the body in through a stoma into the pouch and surround portions of the magnetic core within the pouch. Because of the use of a generally continuous loop magnetic core of high permeability, there is little or virtually no magnetic flux leakage. A solid circular core of a high permeability material may be used. In an alternate embodiment of the present invention the magnetic core can be divided into two separate portions, one implanted within the pouch and one implanted within the peritoneum adjacent the pouch so that the two core portions combine to form a generally continuous loop magnetic path, separated only by the intestinal wall of the pouch.
