Apparatus for controlling flow in a bodily organ

An apparatus for controlling the flow of urine in a urethra of a patient, comprising:

• an implantable adjustable constriction device for constricting the urethra to influence the flow in the urinary tract;
• a control system comprising an internal control unit and an external control unit, wherein the external control unit is configured to communicate instructions to the internal control unit, and the internal control unit is configured to control the constriction device to constrict the urethra or to release a constriction of the urethra;
• and
• an operation device for operating the constriction device to change the constriction of the urethra;
• an energy source for supplying energy for the operation device and the internal control unit;
• wherein
• the internal control unit is connected to an internal signal transmitter, the internal control unit arranged to directly receive measurements related to a current state of the energy source measured on a regular basis and storing information on the current state of the energy source in an internal control unit storage, updating the stored information as new measurements are made, and further arranged to directly transmit a signal reflecting at least a portion of the received measurements to an external signal receiver connected to the external control unit.
