Implantable internal drainage device and system for edemas

A fluid drainage system for drainage of edematous tissues of a patient, the fluid drainage system comprising:

• an inlet catheter having an outlet and an inlet, said inlet catheter comprising a plurality of lumens configured to receive fluid from the edematous tissues, said plurality of lumens running axially parallel in said inlet catheter;
• an outlet catheter having a first end and a second end configured to be anchored at a sink;
• an implantable pump coupled to the outlet of the inlet catheter and the first end of the outlet catheter, the pump having a rotating portion including a permanent magnet formed in the shape of a disk, the rotating portion configured to cause the permanent magnet to rotate eccentrically about an axis of the disk in response to a magnetic force external to the patient, wherein rotations of the permanent magnet create a negative pressure to transport fluid from the inlet of the inlet catheter to the second end of the outlet catheter thereby pumping fluid from the edematous tissues to the sink;
• 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, the external controller configured to be periodically positioned external to the patient and adjacent to the implantable pump.
