摘要： 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.
