Abstract

A transvesicular drainage device configured 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 of a non-human mammal.

Claims

1. Apparatus for draining excess fluid from a patient'"'"'s peritoneal cavity comprising:

a hollow cylinder configured to be disposed across a wall of a patient'"'"'s bladder, the hollow cylinder having an inflow end and an outflow end including a deformable flange configured to be deployed and anchored within the bladder;

an implantable pump having an inlet port and an outlet port;

a first elongated flexible tube coupled in fluid communication between the inflow end of the hollow cylinder and the outlet port of the implantable pump;

a second elongated flexible tube having an exterior diameter, an outlet end coupled to the inlet port of the implantable pump, and an inlet end;

a perforated receptacle coupled to the inlet end of the second elongated flexible tube, the perforated receptacle having a substantially greater diameter than the exterior diameter of the second elongated flexible tube and a multiplicity of pores configured to permit inflow of peritoneal fluid into the perforated receptacle while retarding ingrowth of tissue; and

an electronic valve regulating flow of fluid between the outlet end of the implantable pump and the outflow end of the hollow cylinder,

wherein the apparatus is configured to be triggered via an electric or radio signal.

2. The apparatus of claim 1, wherein the electronic valve is disposed within the hollow cylinder.

3. The apparatus of claim 1, wherein the deformable flange facilitates coupling of the hollow cylinder to the wall of the bladder.

4. The apparatus of claim 1, wherein the perforated receptacle comprises a mesh.

5. The apparatus of claim 1, wherein the electronic valve is controlled through a signal selected from the group of a pressure signal, a mechanical signal, a magnetic signal, an electric signal, and an electromagnetic frequency (EMF) signal.

6. The apparatus of claim 5, wherein the EMF signal is a radio signal.

7. The apparatus of claim 1, wherein the apparatus is configured to provide unidirectional flow of the fluid.

8. The apparatus of claim 1, wherein the apparatus is configured to prevent the spread of infection.

9. The apparatus of claim 8, wherein the apparatus is configured to prevent the spread of infection by providing one or more antibiotic dispensers.

10. The apparatus of claim 8, wherein the apparatus is configured to prevent the spread of infection by providing a material selected from the group consisting of a bacteriostatic material, a bacteriocidal material, an antibiotic eluting material, a material comprising entrained radioisotopes, a material comprising a heating element, a bioactive plastic, and a surface encouraging epithelialization.

11. The apparatus of claim 8, wherein the apparatus is configured to prevent the spread of infection by providing a coating that prevents bacterial adhesion.

12. The apparatus of claim 1, further comprising an anti-clogging device.

13. The apparatus of claim 12, wherein the anti-clogging device is selected from the group consisting of an active ultrasonic component, a sleeve disrupting the flow of the fluid upon active agitation, a surfaces encouraging epithelialization, an enzyme eluting material, a chemical eluting surface, an intermittent plunger mechanism, and a coating preventing adhesion of proteinaceous compounds.
