Implantable device for controlling defecation and related method
First Claim
1. A device implantable in a person for controlling defecation, comprising:
- a first body defining;
an inlet connectable in fluid communication with an intestine of the person 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 person and tissue adjacent to the anal sphincter of the person;
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 person.

Abstract
An implantable device for selectively controlling defecation has an outer body defining on one end a flange that is surgically attachable to the person'"'"'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 person'"'"'s large intestine for connecting the large intestine in fluid communication with the device. 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 device.

20. A method for controlling defecation of a person, comprising the steps of:
-
providing a 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 an intestine of the person;
connecting the outlet of the device to at least one of an anus and a tissue adjacent to the anus of the person;
receiving fecal matter from the 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 person. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. A removable assembly for a device that is implantable in a person for controlling defecation, wherein the device includes an outer body defining an inlet connectable in fluid communication with an intestine of the person for receiving a flow of fecal matter therefrom, and an outlet coupled in fluid communication with the inlet for excreting fecal matter from the inlet therethrough, and connectable to at least one of an anal sphincter of the person and tissue adjacent to the anal sphincter of the person, wherein the removable assembly includes:
-
an inner body receivable within the outer body of the device;
at least one flow control device coupled to the inner body and connectable in fluid communication between the inlet and the outlet of the outer body for controlling the passage of fecal matter therebetween; and
an actuator coupled to the flow control device for controlling actuation of the flow control device and, in turn, controlling defecation by the person. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
