Abstract

An artificial urinary diversion system is disclosed, which consists of a first area with at least one outlet, a second area, and a third area with at least one inlet for accommodating a urinary bladder. The second area is arranged between the first area and the third area, and that the cross-sectional surfaces of the first and/or second areas which are perpendicular to the axial alignment of the urinary diversion system are smaller than the cross-sectional surface of the third area, thereby providing a shape that can be adapted to almost any patient. These artificial urinary diversion systems provide adaptable systems that can be produced without previous direct or indirect determination of the potentially available volume for the system, and that facilitate an as effective as possible determination and utilization during the surgical phase of the volume available in the patient.

Claims

1. Artificial urinary diversion apparatus extending in a longitudinal direction comprising a first portion having a plurality of first cross-sectional areas perpendicular to said longitudinal direction including at least one largest first cross-sectional area and a first outer surface, a second portion having a plurality of second cross-sectional areas perpendicular to said longitudinal direction including at least one largest second cross-sectional area and a second outer surface, and a third portion having a plurality of third cross-sectional areas perpendicular to said longitudinal direction including at least one largest third cross-sectional area and a third outer surface, said second portion being disposed between said first portion and said third portion, said first portion including at least one outlet, said third portion, said at least one largest first cross-sectional area being larger than said at least one largest second cross-sectional area, including at least one inlet, said at least one largest second cross-sectional area being smaller than said at least one largest third cross-sectional area, a sphincter mechanism for opening and closing said outlet, and control means for controlling said sphincter mechanism enclosed entirely within said artificial urinary diversion apparatus defined by said first, second and third outer surfaces.

2. The artificial urinary diversion apparatus of claim 1 including a sensor for sensing the filling level of said apparatus.

3. The artificial urinary diversion apparatus of claim 2 including alarm means for providing an alarm based on said filling level sensed by said sensor.

4. The artificial urinary diversion apparatus of claim 3 wherein said alarm means comprises a sound or seismic alarm signal.

5. The artificial urinary diversion apparatus of claim 2 wherein said sensor is controlled by the nerves responsible for the control of a normal bladder.

6. The artificial urinary diversion apparatus of claim 1 including a power supply.

7. The artificial urinary diversion apparatus of claim 6 wherein said power supply includes an external recharge device and an internal recharge responsive device cooperating with said external recharge device.

8. The artificial urinary diversion apparatus of claim 7 wherein said internal recharge responsive device cooperates inductively with said external recharge device.

9. The artificial urinary diversion apparatus of claim 6 wherein said power supply comprises primary battery means.

10. The artificial urinary diversion apparatus of claim 9 wherein said primary battery means is integrated into said apparatus.

11. The artificial urinary diversion apparatus of claim 1 including a fixing element for fixing said apparatus in a human body.
