Implantable digestive tract organ
First Claim
1. An implantable prosthetic digestive organ comprising:
- an elongate body having an orad end, an aborad end and a lumen therethrough, the elongate body configured to be implanted so as to replace at least a portion of a patient'"'"'s bowel;
at least one sensor which senses leakage of fluid into, out of, or within the elongate body;
a bowel emptying mechanism coupled with the body which is capable of moving digestive material within the lumen from the orad end toward the aborad end; and
a controller in communication with the mechanism for controlling the movement.

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.

6. An implantable prosthetic digestive organ comprising:
-
an elongate body having a first end, a second end and a lumen therethrough, the elongate body configured to be connected with a portion of a digestive tract of a patient so that the lumen is capable of receiving digestive material passing from the portion of the digestive tract; at least two inflatable members disposed along the body which are capable of extending into the lumen upon inflation and retracting from the lumen upon deflation; a pressure sensor configured to sense pressure within at least one of the inflatable members; and a pump connected with the inflatable members which causes the inflation and deflation due to actuation by a controller. - View Dependent Claims (7, 8, 9)
