Abstract

The present invention relates to an implantable apparatus for obtaining urinary control and emptying of the urinary bladder. The apparatus operates with a powered member (100) operating from the outside of the urinary bladder assisted by a support structure to discharge urine from the urinary bladder. A control device (200) controls the operation of the powered member. The control device further comprises a source of energy for operating the powered member and other energy consuming parts of the apparatus and a control assembly.

Claims

1. An apparatus for treating urinary retention of a mammal patient by discharging urine from the urinary bladder, comprising:

an implantable powered member adapted exert a force from the outside on a selected part of the urinary bladder in order to discharge urine from the urinary bladder; and

a control device for controlling the operation of the powered member.

2. An apparatus according to claim 1, wherein said force is exerted at least partly against a support structure.

3. An apparatus according to claim 2, wherein said support structure is adapted to support against at least one of, a bone, such as the pelvic bone, pubic bone or sacrum or spinal cord, other human tissue such as peritoneum, the abdominal or pelvic wall or the urine bladder itself.

4. An apparatus according to claim 1, wherein the control device, comprises a source of energy for operating the powered member and other energy consuming parts of the apparatus.

5. An apparatus according to claim 4, wherein said control device is adapted to be implanted at least partly subcutaneously orin the abdomen or in the pelvic region.

6. An apparatus according to claim 4, wherein the control device, comprises a control assembly adapted to be implanted both subcutaneously and in the abdominal cavity, said control assembly comprising at least two parts adapted to be connected, when implanted.

7. An apparatus according to claim 1, wherein the powered member comprises a contacting part adapted to contact a surface part of the urinary bladder.

8. An apparatus according to claim 7, wherein the powered member comprises at least one operable pressurizer connected to the contacting part in an arrangement, wherein operating the pressurizer provides compression or release of the urinary bladder.

9. An apparatus according to claim 7, wherein the powered member is hydraulically operated to provide compression or release of the urinary bladder.

10. An apparatus according to claim 7, wherein the powered member is mechanically operated to provide compression or release of the urinary bladder.

11. An apparatus according to claim 8, wherein the pressurizer comprises at least one movable arm extending from an operation device to the contacting part of the powered member.

12. An apparatus according to claim 11, wherein the operation device is adapted to displace the movable arm towards the urinary bladder in order to discharge urine from the urinary bladder.

13. An apparatus according to claim 11, wherein the operation device is fixated to human tissue.

14. An apparatus according to claim 11 wherein the operation device is adapted for fixation to the pubic bone.

15. An apparatus according to claim 11, wherein the operation device comprises a motor, preferably an electric motor adapted to displace the movable arm.

16. An apparatus according to claim 9, wherein the pressurizer comprises a reservoir for hydraulic fluid, and wherein the contacting part comprises an expandable cavity hydraulically connected to the reservoir.

17. An apparatus according to claim 16, wherein the pressurizer comprises a pump for transporting the hydraulic fluid from the reservoir to expand the expandable cavity thereby compressing the urinary bladder.

18. An apparatus according to claim 17, wherein the pressurizer is adapted to have the hydraulic fluid transported from the expandable cavity to the reservoir by the urinary pressure in the urinary bladder, when the pump is not active.

19. An apparatus according to claim 12, comprising a second connection between the expandable cavity and the reservoir adapted to admit transportation hydraulic fluid from the expandable cavity to the reservoir by the urinary pressure in the urinary bladder, when the pump is not active.

20. An apparatus according to claim 19, wherein the flow capacity of the second connection is smaller than the pump flow, allowing said second connection to stand open.
