Abstract

A transvesicular drainage device, designed to drain excess fluid from a variety of locations in the human body into the bladder. The device may be used to treat ascites or any fluid collection within the body of a human, or a non human mammal.

Claims

1. A vesicular shunt, comprising:

a hollow cylinder, having an inside and an outside, and also having an inflow end and an outflow end;

a valve, located inside said hollow cylinder, wherein said valve regulates the flow of fluid within the hollow cylinder such that fluid may flow from the inflow end of said hollow cylinder to the outflow end of said hollow cylinder;

wherein said valve is an active-valve controlled through an electric signal; and

a flexible tube, having an inflow and an outflow end, the outflow end of said flexible tube being in fluid communication with the inflow end of said hollow cylinder.

2. A vesicular shunt as recited in claim 1, further comprising:

a first flange, located on the outside of said hollow cylinder near the first end; and

a second flange, located on the outside of said hollow cylinder near the second end.

5. A vesicular shunt as recited in claim 1, further comprising a mesh attached to the inflow end of said hollow cylinder.

6. A vesicular shunt as recited in claim 1, further comprising a perforated receptacle attached to the inflow end of said flexible tube.

7. A vesicular shunt as recited in claim 1, further comprising a valve located within the flexible tube near the inflow end of said flexible tube.

8. A vesicular shunt as recited in claim 1, further comprising a pump, attached to the flexible tube so that said pump is capable of moving fluid from the inflow end of said flexible tube to the outflow end.

3. A vesicular shunt, comprising:

a hollow cylinder, having an inside and an outside, and also having an inflow end and an outflow end;

a valve, located inside said hollow cylinder, wherein said valve regulates the flow of fluid within the hollow cylinder such that fluid may flow from the inflow end of said hollow cylinder to the outflow end of said hollow cylinder;

wherein said valve is an active-valve controlled through an EMF signal; and

a flexible tube, having an inflow and an outflow end, the outflow end of said flexible tube being in fluid communication with the inflow end of said hollow cylinder.

4. A vesicular shunt as recited in claim 3, wherein said EMF signal is a radio signal.

9. A vesicular shunt for draining bodily fluids, comprising:

a tube, wherein said tube is designed to be implanted in the wall of the bladder;

a means for preventing the passage of solids through said tube;

a means for anchoring said tube in the wall of the bladder; and

a means for ensuring unidirectional flow through said tube.

10. A vesicular shunt as recited in claim 9, wherein said means for anchoring is a pair of flanges.

11. A vesicular shunt as recited in claim 9, wherein said means for anchoring is a suture.

12. A vesicular shunt as recited in claim 9, wherein said means for ensuring unidirectional flow is a valve.

13. A vesicular shunt as recited in claim 12, wherein said valve is a ball-valve.

14. A vesicular shunt as recited in claim 12, wherein said valve is a flapper-valve.

15. A vesicular shunt as recited in claim 12, wherein said valve is an active-valve.

16. A vesicular shunt as recited in claim 15, wherein said active-valve is controlled through an EMF signal.

17. A vesicular shunt as recited in claim 16, wherein said EMF signal is a radio signal.

18. A vesicular shunt as recited in claim 15, wherein said active-valve is controlled through an electric signal.

19. A vesicular shunt as recited in claim 15, wherein said active-valve is controlled through a pressure signal.

20. A vesicular shunt as recited in claim 15, wherein said active-valve is controlled through a mechanical signal.

21. A vesicular shunt as recited in claim 15, wherein said active-valve is controlled through a magnetic signal.

22. A vesicular shunt as recited in claim 12, further comprising a pump means for speeding the collection of fluid.

23. A vesicular shunt as recited in claim 12, further comprising a pump, wherein said pump is configured to transport fluid through the tube means for deposition in the bladder.

24. A vesicular shunt as recited in claim 12, wherein said tube means includes a valve located within said tube means.

25. A vesicular shunt as recited in claim 9, further comprising an anti-infective means.

26. A vesicular shunt as recited in claim 25, wherein said anti-infective means is a surface which encourages epithelialization.

27. A vesicular shunt as recited in claim 25, wherein said anti-infective means is a bactericidal material.

28. A vesicular shunt as recited in claim 25, wherein said anti-infective means is an entrained radioisotope.

29. A vesicular shunt as recited in claim 9, further comprising an anti-clogging means.

30. A vesicular shunt as recited in claim 29, wherein said anti-clogging means is an active ultrasound component.

31. A vesicular shunt as recited in claim 29, wherein said anti-clogging means is an inner and outer lumen.

32. A vesicular shunt as recited in claim 29, wherein said anti-clogging means is a surface which promotes epithelialization.

33. A vesicular shunt as recited in claim 29, wherein said anti-clogging means is an enzyme eluting material.

34. A vesicular shunt as recited in claim 9, further comprising a transport means for collecting fluid from remote interstices.

35. A method for draining excess fluid into the bladder of a living host, comprising:

Implanting into the wall of the bladder a hollow cylinder, having an inside and an outside, and also having an inflow end and an outflow end;

a valve, located inside said hollow cylinder, wherein said valve regulates the flow of fluid within the hollow cylinder such that fluid may flow from the inflow end of said hollow cylinder to the outflow end of said hollow cylinder;

a flexible tube, having an inflow and an outflow end, the outflow end of said flexible tube being in fluid communication with the inflow end of said hollow cylinder;

implanting the inflow end of the tube into the region to be drained, wherein the region to be drained is the pleural cavity.

36. The method of claim 35, wherein the host is a non-human mammal.

37. The method of claim 35, wherein the host is equine.

38. The method of claim 35, wherein the host is bovine.
