ABSTRACT:
An implantable device for selectively opening and closing a tubular organ of the body such as the urethra has an elongate valve body which can be introduced into the tubular organ. The valve body has a shut-off means which can be selectively closed and opened, for which purpose the valve body has an elastic hose portion in which there is disposed an inflation body which can be inflated by a fluid to then close the lumen of the hose portion. The fluid can be conveyed out of the inflation body into a storage container by actuation of an implantable pump so the inflation body collapses and permits a flow through the valve body. Manual actuation of a non-return valve in the pump causes fluid to flow out of the storage container into the inflation body to inflate same and close the valve body.
