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. The invention also extends to a filter adapted to filter particles from a drained fluid.

Claims

1. A filtering device for removing particles from a fluid of a patient, the filtering device being implantable in the patient'"'"'s body and comprising:

a tube forming a fluid passageway,

an active filter connected to the tube for filtering any particles passing through the tube, wherein said filter is adapted to move any particles away from the fluid passageway, when the filter being implanted in the patients body.

2. The device according to claim 1, comprising a cassette for changing the filter.

3. The device according to claim 1, comprising a cleaning device for cleaning the filter.

4. The device according to claim 1, wherein the filter and or cassette is powered by a motor.

5. The device according to claim 4, wherein the motor is connected to an internal power supply.

6. The device according to claim 5, wherein the power supply is connected to the filter and to the cassette.

7. The device according to claim 5, wherein the power supply is connected to a pump for moving fluid through the fluid passageway.

8. The device according to claim 2, comprising a revolving cylinder revolving over the fluid passage way.

9. The device according to claim 8, wherein the revolving cylinder revolving over the fluid passage way comprises a number of segments.

10. The device according to claim 9, wherein segments are adapted to hold a filter.

11. The device according to claim 8, further comprising a magazine adapted to hold a number of cylinders.

12. The device according to claim 3, wherein the cleaning device is adapted to move any particles away from the fluid passageway.

13. The device according to claim 3, wherein the cleaning device is adapted to move particles to a location within the body of the patient.

14. The device according to claim 3, wherein the cleaning device is adapted to take into account the fibrotic capsula covering the cleaning device when implanted.

15. The device according to claim 3, wherein the filter comprises a rotating member.

16. The device according to claim 3, wherein the cleaning device is adapted to slice, push or scratch away any particles from the filter.

17. The device according to claim 1, wherein the active filter is adapted be cleaned by sucking away any particles from the filter.

18. The device according to claim 17, wherein the filter is of biocompatible material.

19. The device according to claim 17, wherein the filter comprises a plurality of strips.

20. The device according to claim 19, wherein the plurality of strips are equally spaced.
