Abstract

An implantable fluid movement 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 and further adapted to secure the tube end of the fluid movement device to a location inside a treated patient.

First claim

The invention claimed is:

1. An apparatus for moving a fluid to or from a cavity in 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:
the fluid movement device and the at least one connecting tube form a fluid moving arrangement adapted to be implanted inside the body of the human or mammal patient;
the tube end is adapted to be inserted into an organ of the patient;
at least a portion of the apt least one connecting tube is adapted to be invaginated in a wall of the organ so as to interconnect a treatment area of the body with a delivery area;
the fluid movement device is adapted to move fluid from the treatment area via the at least one connecting tube to the delivery area;
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 at a distance from the tube end to allow the flexible patch to be attached to an outer surface of the organ when the at least one connecting tube is invaginated in the wall of the organ, wherein the flexible patch is further adapted to be arranged with a lateral extension along the outer surface of the organ so as to fixate and seal the at least one connecting tube to the organ by means of overgrowth of human fibrotic tissue.

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, farther 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:
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 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 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 tube 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 11 , wherein the net structure is provided with holes having a diameter suitable for overgrowth by tissue.

13. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 12 , wherein the diameter of the holes is smaller than 2.5 mm.

14. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 12 , wherein the diameter of the holes is smaller than 1.5 mm.

15. The apparatus for moving a fluid to or from a cavity in a human or mammal patient according to claim 12 , wherein the diameter of the holes is smaller than 0.5 mm.

16. 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.

17. The apparatus for moving a fluid to or from a cavity in a
