Abstract: Disclosed are a fluid drainage devices and methods of use for drainage of edematous tissues of a patient. The devices include an inlet catheter comprising a plurality of lumens configured to receive fluid from the edematous tissues, wherein the plurality of lumens run axially parallel in the inlet catheter; an outlet catheter configured to be anchored at a sink; an implantable pump coupled to the inlet catheter and the outlet catheter, the pump having a rotating portion including a permanent magnet, the rotating portion configured to rotate in response to a magnetic force external to the patient to move fluid from the inlet of the inlet catheter to the second end of the outlet catheter; and an external controller configured to transcutaneously couple to the permanent magnet of the rotating portion to apply the magnetic force to the implantable pump.

Abstract: A medical fluid drainage system which may be advantageously used to actively absorb excess fluid from an interstitium in a living host and to transport it from an inlet member 1 in a non edematous body part out of an outlet member 4 via pumps (5, 6, 7) built in series, such as a distal area with functional lymphatic vessels, or directly in a lymphatic vessel, or directly in a blood vessel.

Abstract: The invention relates to a medical fluid drainage device for drainage of edematous tissues comprising at least one pumping element (1, 23, 33), having an inlet and an outlet, at least one outlet member (2) having at least one lumen, connected directly or indirectly to the outlet of said pumping element and connecting said pumping element to a body cavity or to a vessel or to a subcutaneous area, and at least one inlet member (3) connected to said inlet of said pumping element and providing fluidic connection between said edematous tissue and said pumping element, and characterized in that the inlet member comprises at least two inlet lumens (4, 5, 6) connected in parallel to said inlet of said pumping element, each of said lumens (4, 5, 6) contains at least one fluid access region, wherein each fluid access region (8, 9, 10) being adapted to allow simultaneous edematous fluid entry from distinct regions of said edematous tissue.
