Artificial rectum and related method
First Claim
1. An artificial rectum implantable in a patient for controlling defecation, comprising:
- a first body defining;
an inlet connectable in fluid communication with a large intestine of the patient for receiving a flow of fecal matter therefrom; and
an outlet coupled in fluid communication with the inlet for excreting fecal matter from the first inlet therethrough, and connectable to at least one of an anal sphincter of the patient and tissue adjacent to the anal sphincter of the patient;
at least one flow control device coupled in fluid communication between the first inlet and the first outlet for controlling the passage of fecal matter from the first inlet through the first outlet; and
an actuator coupled to the flow control device for controlling actuation of the flow control device and, in turn, controlling defecation by the patient.

Abstract
An implantable device for selectively controlling defecation has an outer body defining on one end a flange that is surgically attachable to the patient'"'"'s anus and/or tissue adjacent to the anus. A connector is mounted on the other end of the outer body and is secured to the distal end of the patient'"'"'s large intestine for connecting the large intestine in fluid communication with the artificial rectum. An inner body is slidably received within the outer body. A macerator-type pump is mounted within the inner body and an inlet valve is mounted between the pump and the connector. An actuator in the form of an RF receiver is electrically coupled to the inlet valve and the pump and a remote transmitter is operatively coupled to the receiver. The receiver is responsive to control signals received from the transmitter to open the inlet valve and operate the pump in order to move fecal matter through the artificial rectum.

10. An artificial rectum implantable in a patient for controlling defecation, comprising:
-
first means connectable in fluid communication with a large intestine of the patient for receiving a flow of fecal matter therefrom;
second means connectable to at least one of an anal sphincter and tissue adjacent to the anal sphincter of the patient and coupled in fluid communication with the first means for excreting fecal matter therethrough;
third means coupled in fluid communication between the first and second means for controlling the flow of fecal matter from the first means through the second means; and
fourth means coupled to the third means for controlling actuation of the third means and, in turn, controlling the flow of fecal matter through the artificial rectum. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method for providing an artificial rectum in a patient for controlling defecation, comprising the steps of:
-
providing an artificial rectum having an inlet, an outlet, and at least one flow control device coupled in fluid communication between the inlet and the outlet;
connecting the inlet of the artificial rectum in fluid communication with a large intestine of the patient;
connecting the outlet of the artificial rectum to at least one of an anus and a tissue adjacent to the anus of the patient;
receiving fecal matter from the large intestine through the inlet of the artificial rectum, and controlling the flow control device to selectively move the fecal matter between the inlet and the outlet, and, in turn, discharge the fecal matter through the outlet to thereby control defecation of the patient. - View Dependent Claims (21, 22, 23, 24, 25, 26)
