Abstract

An apparatus for moving a fluid to or from a cavity on a body of a human or mammal patient. The apparatus comprising a fluid movement device, an energy source adapted to supply energy to said fluid movement device and at least one connecting tube having a tube end. The at least one connecting tube being connected to the fluid movement device. The apparatus further comprises, a flexible patch. The fluid movement device and the at least one connecting tube forms a fluid moving arrangement adapted to be implanted inside the body of the human or mammal patient. The fluid movement device is adapted to move fluid from a treatment area via the at least one connecting tube to a delivery area. The flexible patch comprises a net structure adapted to be overgrown by human fibrotic tissue hen implanted in the patient.

First claim

The invention claimed is:

1. An apparatus for moving a fluid to or from a cavity on a body of a human or mammal patient, comprising:
a fluid movement device;
an energy source adapted to supply energy to said fluid movement device;
at least one connecting tube having a tube end, the at least one connecting tube being connected to the fluid movement device; and
a flexible patch;

wherein, when the apparatus is in use:
the fluid movement device and the at least one connecting tube form a fluid moving arrangement implanted inside the body of the human or mammal patient;
the fluid movement device is adapted to move fluid from a treatment area via the at least one connecting tube to a delivery area;
the at least one connecting tube is inserted into an organ of the human or mammal patient, wherein said connecting tube is entered into said organ in a tube passageway; and
the flexible patch is positioned on an outside surface of the organ and acts as a combined securing and sealing device for the at least one connecting tube, wherein;
the flexible patch comprises a net structure adapted to be overgrown by human fibrotic tissue when implanted in the human or mammal patient; and
the flexible patch is arranged for overgrowth of human fibrotic tissue, thereby sealing said net structure and attaching said net structure to said surface of said organ of said human or mammal patient.

2. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 1 , wherein the net structure is sealed around the at least one connecting tube.

3. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 1 , wherein the net structure is provided with holes having a diameter suitable for overgrowth by tissue.

4. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 3 , wherein the diameter of the holes is smaller than 2.5 mm.

5. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 3 , wherein the diameter of the holes is smaller than 1.5 mm.

6. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 3 , wherein the diameter of the holes is smaller than 0.5 mm.

7. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 1 , wherein the at least one connecting tube comprises:
at least one first connecting tube connected to said fluid movement device adapted to drain urine from a renal part of a kidney accumulating urine, and
at least one second connecting tube adapted to be connected to an urine bladder and passing through a wall of said urine bladder, further adapted to be invaginated in the wall of the urine bladder thereby creating a tunnel around the second connecting tube, the at least one first connecting tube, the at least one second connecting tube and the fluid movement device being implantable in the body and adapted to move urine from the renal part of the kidney to the urine bladder, using power from said energy source, wherein said at least one second connecting tube includes said net structure adapted to seal a tube passageway out from the urine bladder, when invaginated by the wall of the urine bladder, by overgrowth of human tissue in an outer opening of the tunnel.

8. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 1 , wherein the at least one connecting tube comprises:
at least one first connecting tube connected to said fluid movement device adapted to drain liquid from a hydrocephalus in a brain area, and
at least one second connecting tube adapted to be connected to an abdomen, the at least one first connecting tube, the at least one second connecting tubes, and the fluid movement device, being adapted to be implanted inside the body, the fluid movement device further being adapted to move liquid from the hydrocephalus to the abdomen, using power from said energy source.

9. The apparatus for moving a fluid to or front a cavity in a human or mammal patient according to claim 1 , wherein the at least one connecting tube comprises:
at least one first connecting tube connected to said fluid movement device adapted to drain liquid from an ascites in an abdomen, and
at least one second connecting tube adapted to be connected to a lymphatic system of the body, the at least one first connecting tube, the at least one second connecting tube, and the fluid movement device being adapted to be implanted inside the body, the fluid movement device further being adapted to move liquid from the ascites in the abdomen into the lymphatic system using power from said energy source.

10. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 1 , wherein the at least one connecting tube comprises:
at least one first connecting tube connected to said fluid movement device adapted to drain liquid from ascites in an abdomen, and
at least one second connecting tube adapted to be connected to an urine bladder of the body and passing through a wall of said urine bladder, further adapted to be invaginated in the wall of the urine bladder thereby creating a tunnel around the tube, the at least one first and second connecting tubes and the fluid movement device being adapted to be implanted inside the body, the fluid movement device further being adapted to move liquid from the ascites in the abdomen into the urine bladder, using power from said energy source, wherein said second connecting tube includes said net structure adapted to seal the tube passageway out from the urine bladder, when invaginated by the same, by overgrowth of human tissue in an outer opening of the tunnel.

11. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 1 , wherein the at least one connecting tubes comprises:
at least one first connecting tube connected to said fluid movement device adapted to drain liquid from a thoraxial cavity, and
at least one second connecting tube adapted to be connected to an abdomen, the at least one first and second connecting tubes and the fluid movement device being adapted to be implanted inside the body, the fluid movement device further being adapted to move liquid from a thorax to the abdomen, using power from said energy source.

12. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 1 , comprising:
a filter for filtering the fluid being moved by the fluid movement device and
a cleaning device to clean the filter.

13. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 12 , wherein the cleaning device is adapted to move any cleaned particles outside a flow passageway wherein the fluid is passing.

14. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 1 , wherein a tube area between the net structure and the organ is adapted to be invaginated in the organ wall.

15. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 1 , wherein the net structure is sealed around the tube.

16. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 11 , wherein the net structure is provided with holes having a diameter suitable for overgrowth by tissue.

17. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim
