System for treating a patient having an intestinal disorder

A system for treating a patient having a disorder related to a patient's intestine and further having a reservoir which is provided for receiving and temporarily collecting therein intestinal contents, the reservoir being formed from surgically modified intestine that has been cut along a mutual contact line of laterally adjacent sections of a bent portions of intestine and connected so that the resulting upper and lower halves of the bent portions of intestine form an intestinal wall of the reservoir, the reservoir having an entry and an exit for the intestinal contents to enter into and exit from the reservoir and further having a length between the entry and the exit and a width of 10 cm or more, wherein the system comprises an artificial flow control device implantable in the patient's body and adapted to control flow of the intestinal contents from said reservoir, the flow control device comprising at least one pump adapted to act on said intestinal wall so as to reduce the reservoir's volume, thereby emptying the reservoir, wherein the at least one pump comprises a pump adapted to act on said intestinal wall from outside of the reservoir so as to empty the reservoir by squeezing the reservoir from the outside thereof,

• (a) wherein the at least one pump comprises a hydraulic pump, a hydraulically acting member for acting on said intestinal wall from the outside of the reservoir, and an artificial reservoir, wherein the hydraulic pump is adapted to pump hydraulic fluid from the artificial reservoir to the hydraulically acting member, wherein the hydraulically acting member is configured to accommodate the reservoir therein, or
• (b) wherein the at least one pump comprises at least one mechanically acting member for acting on said intestinal wall from the outside of the reservoir and a motor adapted to drive the at least one mechanically acting member for emptying the reservoir, wherein the at least one mechanically acting member is a roller adapted to be rolled over the reservoir for emptying the reservoir.
