1. A system comprising:
- an implantable fluid penetrable chamber comprising a frame having flat permeable sides, wherein said frame is covered by a fluid permeable membrane mesh configured to enable fluids of a tissue contacting said fluid permeable membrane mesh to penetrate directly from said tissue into said implantable fluid penetrable chamber through said flat permeable sides;
a catheter connected at a first end to one side of said chamber or penetrates therethrough;
and further comprising a pump placed inside or outside of said chamber.

11. A method for draining excessive fluid from a body cavity or space, said method comprising the steps of:
-
a) implanting a device within said body cavity or space; wherein said device comprises an implantable fluid penetrable chamber comprising a frame having flat permeable sides covered by a fluid permeable membrane mesh configured to encourage fluids of a tissue contacting said fluid permeable membrane mesh to penetrate directly from said tissue into said chamber through said flat permeable sides; a catheter connected at a first end to one side of said chamber or penetrates therethrough; and further comprising a pump placed inside or outside of said chamber; b) contacting at least part of a tissue by said fluid permeable membrane mesh covering said chamber; c) positioning the second end of said catheter within the cavity of a urinary system organ; such that changes in pressure within said catheter and/or changes in pressure exerted within said chamber by said pump result in the ingress of fluid from tissue contacting said flat permeable sides directly into said chamber. - View Dependent Claims (12, 13, 14, 15)

16. A method for draining excessive fluid from a body cavity or space, said method comprising the steps of:
-
a) implanting a device within said body cavity or space; wherein said device comprises an implantable fluid penetrable flat chamber comprising a frame, said flat chamber having flat permeable sides surrounded by a fluid permeable membrane mesh configured to encourage fluids of a tissue contacting said fluid permeable membrane mesh to penetrate directly from said tissue into said flat chamber through said flat permeable sides; a catheter connected at a first end to one side of said flat chamber or penetrates therethrough; and further comprising a pump placed inside or outside of said chamber; b) draining excessive fluid by contacting at least part of a tissue by said fluid permeable membrane mesh surrounding said chamber.

19. A system comprising:
-
an implantable fluid penetrable chamber comprising a planar spiral frame which emanates from a central point and getting progressively farther away as it revolves around the point, wherein said planar spiral frame is covered by a fluid permeable membrane mesh configured to enable fluids to penetrate therethrough; a catheter connected at a first end to one side of said chamber or penetrates therethrough; and further comprising a pump placed inside or outside of said chamber.
