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.

First claim

The invention claimed is:

1. An apparatus for treating urinary retention of a mammal patient by discharging urine from the urinary bladder in order to empty the urinary bladder, comprising:
an implantable powered member comprising:
a first part comprising a urinary bladder surface contact part adapted to exert a force from the outside of the urinary bladder on a selected surface part of the urinary bladder in order to actively compress the urinary bladder for reducing the volume of the urinary bladder to discharge urine from the urinary bladder to empty the urinary bladder, wherein the powered member is adapted to, via the urinary bladder surface contact part, empty the urinary bladder by exerting the force, the force being strong enough to force urine out from the urinary bladder through a urethra to thereby empty the urinary bladder, and
a second part being at least a part of a support structure adapted to be fixed to human tissue, wherein the force of the powered member exerted towards the urinary bladder is held at least partially against the support structure, said support structure being adapted to be supported against at least one of the pelvic bone, the pubic bone, sacrum, the spinal cord, the peritoneum, the abdominal wall, the pelvic wall, and the urinary bladder, wherein the force exerted by the urinary bladder contact part to empty the urinary bladder is configured to be held against human tissue via the second part and the support structure adapted to be fixed to human tissue, when the apparatus is implanted, and

a control device for controlling the operation of the powered member to discharge urine from the urinary bladder to empty the urinary bladder, thereby control the emptying of the urinary bladder, and
wherein the powered member is hydraulically operated to provide compression or release of the urinary bladder.

2. The apparatus according to claim 1 , wherein the control device comprises an implanted source of energy for operating the powered member and other energy consuming parts of the apparatus.

3. The apparatus according to claim 2 , wherein said control device is adapted to be implanted at least partly subcutaneously or in the abdomen or in the pelvic region.

4. The apparatus according to claim 2 , wherein the control device is adapted to be implanted both subcutaneously and in the abdominal cavity, said control device comprising at least two parts adapted to be connected, when implanted.

5. The apparatus of claim 1 , comprising an operable pressurizer comprising a reservoir for hydraulic fluid, and wherein the urinary bladder surface contact part comprises an expandable cavity hydraulically connected to the reservoir.

6. The apparatus according to claim 5 , wherein the operable pressurizer comprises a pump for transporting the hydraulic fluid form the reservoir to expand the expandable cavity thereby compressing the urinary bladder.

7. The apparatus according to claim 6 , wherein the operable 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.

8. The apparatus according to claim 1 , comprising a sensor for measuring any parameter related to the urinary pressure or volume of the urinary bladder.

9. The apparatus according to claim 8 , wherein said sensor is capable of sending a signal to the control device, which thereby is adapted to send an alarm information out from the body of the patient as a request for activating the powered member.

10. The apparatus according to claim 1 , adapted to be included in a system, comprising a wireless energy-transmission device for non-invasively energizing implantable energy consuming components of the apparatus with wireless energy.

11. The apparatus according to claim 10 , adapted to be included in the system, further comprising an energy-transforming device for transforming the wireless energy transmitted by the wireless energy-transmission device from a first form into a second form of energy, wherein the energy-transforming device is adapted to perform at least one of the following as the energy-transforming device transforms the first form of energy transmitted by the wireless energy transmission device into the second form of energy:
a) directly power implantable energy consuming components of the device with the second form of energy or
b) when the system further comprises an implantable internal energy source for powering implantable energy consuming components of the device and being chargeable by the wireless energy, power an internal energy source with the second form of energy, when the system comprises the implantable internal energy source.

12. The apparatus according to claim 10 , adapted to be included in the system, further comprising:
a control device for controlling the transmission of wireless energy from the energy-transmission device,
an implantable internal energy receiver for receiving the transmitted wireless energy, the internal energy receiver being connected to the implantable energy consuming components of the apparatus for directly or indirectly supplying received energy thereto, and
a determination device adapted to determine an energy balance between the energy received by the internal energy receiver and the energy used for the implantable energy consuming components of the apparatus,
Wherein, the control device controls the transmission of wireless energy from an external energy-transmission device, based on the energy balance determined by the determination device, wherein the determination device is adapted to detect at least one of:
a) a change in the energy balance, and the control device controls the transmission of wireless energy based on the detected energy balance change, and
b) a difference between the energy received by the internal energy receiver and energy used for the implantable energy consuming components of the apparatus, and the control device controls the transmission of wireless energy based on the detected energy difference.

13. The apparatus according to claim 1 , adapted to be included in a system, farther comprising a feedback device for sending feedback information from inside the patient's body to the outside thereof, the feedback information being related to at least one of
a physical parameter of the patient and a functional parameter related to the apparatus, wherein at least one functional parameter is correlated to the transfer of wireless energy.

14. The apparatus according to claim 1 , adapted to be included in a system, further comprising a sensor or a measuring device and an implantable control unit for controlling the apparatus in response to information being related to at least one of a) a physical parameter of the patient sensed by the sensor or measured by the measuring device and b) a functional parameter related to the apparatus sensed by the sensor or measured by the measuring device.

15. The apparatus according to claim 1 , adapted to be included in a system, further comprising implantable electrical components including at least one of:
a voltage level guard and a constant current guard.

16. The apparatus according to claim 1 , being adapted to be included in a system, further comprising an external data communicator and an implantable internal data communicator communicating with the external data communicator, wherein the internal communicator feeds data related to said apparatus or the patient to the external data communicator and the external data communicator feeds data to the internal data communicator.
