Abstract

An implantable drainage device is provided. The device is adapted to move body fluid from one part of the body of a patient to another part of the body.

Claims

1. An apparatus for drainage of a body fluid in the body of a human or mammal patient, comprising:

a pump;

an implantable internal energy source adapted to supply energy to said pump, the internal energy source comprising an energy storing device for storing energy;

at least one tube connected to said pump, wherein the tube and the pump are adapted to be fully implanted in the body of a human or mammal patient, wherein the pump is adapted to pump liquid from ascites in the abdomen to another part of the body, using power from said internal energy source, wherein the pump includes an expanding reservoir comprising;

a bellow having an inlet with an inlet valve and an outlet with an outlet valve,

a member adapted to move the bellow to expand to suck fluid, and

a motor adapted to compress the bellow and move fluid out, wherein said pump is adapted to continuously repeat expansion and compression of the bellow, whereby body fluid is removed from a treatment area to a delivery area;

an external energy source adapted to transmit wireless energy to charge said implantable internal energy source; and

a control unit for controlling the charging of the implantable internal energy source;

wherein the control unit is configured to;

receive temperature input related to the charging of the internal energy source, and control the charging of the internal energy source on the basis of the received temperature input.

2. An apparatus according to claim 1, wherein the apparatus is further adapted to send feedback information from inside the body to the outside thereof to give feedback related to any functional parameter of the device of physical parameter of the patient.

3. The apparatus according to claim 2, wherein the functional parameter of the device is correlated to the transfer of energy for charging the internal energy source.

4. The apparatus according to claim 2, further comprising a device adapted to receive transmitted wireless ultra-sonic energy.

5. The apparatus according to claim 2, further comprising a device adapted to receive transmitted wireless inductive energy.

6. The apparatus according to claim 1, adapted to be placed in the abdomen.

7. The apparatus according to claim 1, further comprising a wireless remote control, wherein the apparatus is adapted to non-invasively have any of its functions regulated by said remote control.

8. The apparatus according to claim 1, comprising a wireless energy transmitter, wherein the apparatus is adapted to non-invasively have any of its functions regulated by said energy transmitter.

9. An apparatus according to claim 1, further comprising an implantable energy transforming device connected to the energy storing device for transforming energy for storing in the energy storing device.

10. An apparatus according to claim 1, further comprising a first coil arranged in the implanted energy transforming device, and a second coil arranged in the external energy source, wherein the coils are adapted for inducing current in the first coil.

11. An apparatus according to claim 1 further comprising a sensor for measuring a physical parameter of the patient or a functional parameter of the device, wherein the sensor measurements are transmitted directly to the external control unit, and wherein the control unit is adapted to determine a required amount of energy to be transferred.

12. An apparatus according to claim 1, wherein the control unit is adapted to control the charging of the implantable energy source by adjusting a transmission parameter in the external energy source, wherein the transmission parameter comprises a voltage.

13. An apparatus according to claim 1, wherein the control unit is adapted to control the charging of the implantable energy source by adjusting a transmission parameter in the external energy source, wherein the transmission parameter comprises a current.

14. An apparatus according to claim 1, wherein the control unit is adapted to control the charging of the implantable energy source by adjusting a transmission parameter in the external energy source, wherein the transmission parameter comprises a wave amplitude.

15. An apparatus according to claim 1, wherein the control unit is adapted to control the charging of the implantable energy source by adjusting a transmission parameter in the external energy source, wherein the transmission parameter comprises a wave frequency.

16. An apparatus according to claim 1, wherein the control unit is adapted to control the charging of the implantable energy source by adjusting a transmission parameter in the external energy source, wherein the transmission parameter comprises a pulse characteristics.

17. An apparatus according to claim 1, further comprising an implantable temperature sensor for measuring a temperature related to the internal energy source or a body temperature of the patient to provide a temperature input related to the charging of the internal energy source.
