ABSTRACT:
An implantable digestive organ is provided for the transport of materials through the digestive tract and in one particular application to an artificial large bowel for replacing all or part of a colon or large bowel. The prosthetic organ of one embodiment includes an outer support structure, an expandable member or members located within the outer support structure, and a flexible inner member forming a conduit for the passage of material. The flexible inner member is located within the outer member and the expandable member or members are located between the inner member and the outer support structure. The expandable members are expanded and contracted, or inflated and deflated to provide a pumping action that pumps the material through the organ. The prosthesis may also include valves or sphincters at the entrance and/or exit points of the organ where material moves into and out of the prosthesis. An implantable pump unit may be included for inflating and deflating the expandable members according to a desired sequence.
