Abstract

An implantable device for selectively controlling defecation (10) has an outer body (16) defining a flange (16) that is surgically attachable to the patient's anus and tissue adjacent to the anus. A connector (22) mounted on the other end of the outer body (16) and secured to the distal end of the large intestine for connecting the large intestine in fluid communication with the artificial rectum (10). An inner body (30) is slidably received within the outer body (16). A pump (42) mounted within the inner body (30) and an inlet valve (40) mounted between the pump (42) and the connector (22). An actuator (15) in the form of an RF receiver is electrically coupled to the inlet valve (40) and the pump (42) and a remote transmitter (15) operatively coupled to the receiver (50). The receiver (50) responsive to control signals received from the transmitter (15) to open the inlet valve (40) and operate the pump (42) to move fecal matter through the artificial rectum (10).

Claims

AMENDED CLAIMS [received by the International Bureau on 14 December 2004 (14.12.2004); original claims 1-23, 25 and 26 amended; claim 24 unchanged (4 pages)]
WHAT IS CLAIMED IS: 1. A device iniplantable 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 How 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. 2. A device as recited in claim 1, wherein the first body further defines an annular recess for engaging the anal tissue of the patient. 3. A device as recited in claim 1 , further comprising a connector for connecting the colon in fluid communication to the inlet. 4. A device as recited in claim 1 , wherein the at least one flow control device is a pump. 5. A device as recited in claim 1, wherein the at least one flow control device is a valve. 6. A device as recited in claim 1, further comprising a second body releasably connected to the first body, wherein the second body defines a second inlet and a second outlet and the flow control device is coupled to the second body. 7 A device as recited in claim 6, further comprising a cover for sealing the second outlet. 8. A device as recited in claim 1 , further comprising a gas-release valve. 9, A device as recited in claim 1 , wherein the actuator includes: a remote transmitter for sending a signal; and a receiver coupled to the flow control device for receiving the signal and actuating the flow control device in response thereto.
10. A device 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 ecal 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 device. 11. A device as recited in claim 10, wherein the first means is defined by an inlet adapted to be fixably coupled to the large intestine of the patient and forming a pressure-tight seal with the large intestine. 12. A device as recited in claim 10, wherein the second means is defined by an outlet adapted to be surgically attached to at least one of an anal sphincter and tissue adjacent to the anal sphincter. 13. A device as recited in claim 10, wherein the third means is a pump. 14. Λ device as recited in claim 10, wherein the third means is a valve. 1 . A device as recited in claim 10, wherein the fourth means is a receiver coupled to the third means for receiving a signal and actuating the third means in response thereto to induce a flow of fecal matter through the device. 16. A device as recited in claim 15, wherein the fourth means further includes a transmitter for transmitting the signal to the receiver. 17. A device as recited in claim 10, further comprising fifth means for releasing gas through the device. 18. A device as recited in claim 11, wherein the fifth means is defined by a conduit adapted to be coupled in fluid communication between the large intestine and the exterior of the device. 19. A device as recited in claim 18. further comprising a valve coupled in fluid communication with the conduit for allowing the passage of gas through the conduit when the pressure on an inlet side of the valve exceeds a threshold value.
AMENDED SHEET (ARTICLE 19) 16
20. A method for providing a device in a patient for controlling defecation, comprising the steps of: providing the device 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 device in fluid communication with a large intestine of the patient; connecting the outlet of the device to al least one of an anus and a tissue adjacent to the anus of the patient; receiving fecal matter fro the large intestine through the inlet of the device, 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. 21. A method as recited in claim 20- wherein the step of connecting the inlet of the device in fluid communication with a large intestine of the patient includes fixably securing the inlet of the device to the large intestine. 22. A method as recited in claim 20, wherein the step of connecting the outlet of the device to at least one of an anus and a tissue adjacent to the anus of the patient includes surgically attaching the outlet of the device to at least one of an anus and a tissue adjacent to the anus of the patient. 23. A method as recited in claim 20, wherein the at least one flow control device includes a valve, and the step of controlling the flow control device to selectively move the fecal matter includes opening the valve and permitting the flow of fecal matter between the inlet and outlet, and closing the valve and preventing the flow of fecal matter between the inlet and outlet. 24. A method as recited in claim 20, wherein the at least one flow control device includes a pump, and the step of controlling the flow control device to selectively move the fecal matter includes actuating the pump to pump fecal matter between the inlet and the outlet. 25. A method as recited in claim 20, wherein the step of controlling the flow control device to selectively move the fecal maUer between the inlet and the outlet includes remotely actuating the flow control device to move the fecal matter through the device.
AMENDED SHEET (ARTICLE 19) 17
26. A method as recited in claim 20, wherein the step of receiving fecal matter from the large intestine includes receiving gases from the large intestine and venting the gases through the device.
