First Claim
Patent Images
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.

22. A method of securing at least one connecting tube for use in an implantable device for implantation in a human or mammal body, wherein the at least one connecting tube is adapted to move a body fluid or a hydraulic treatment fluid from one part of the human or mammal body, via the at least one connecting tube to another part of the human or mammal body, the at least one connecting tube having a distal end adapted to be located in an organ of the human or mammal body for drainage of the body fluid or in a reservoir for movement of the hydraulic treatment fluid, from a treatment area of the human or mammal body into the organ, the method comprising the steps of:
-
cutting the skin, dissecting the treatment area, opening a hole in the organ, placing an end of the at least one connecting tube in the organ, securing the at least one connecting tube on an outside of the organ by invaginating the at least one connecting tube using sutures or staples, thus creating an invaginated tunnel around the at least one connecting tube, wherein said at least one connecting tube comprises a flexible patch comprising a net material secured to said at least one connecting tube, the method further comprising, placing the net material in connection to an opening of the invaginated tunnel such that the patch has a lateral extension along an outer surface of the organ, and securing the net material to the outer surface of the organ.
