Hemodialysis Device

A dialysis tube for a hemodialysis device comprising:

• an outer dialysis tube having a first end, a second end, and an intermediate cavity;
• an inner dialysis tube disposed within the intermediate cavity, the inner dialysis tube having an inlet, an outlet, and an interior cavity, the inlet and the outlet disposed at a first end of the outer dialysis tube;
• and
• a dialysis membrane, the interior cavity being in partial fluid communication with the intermediate cavity across the dialysis membrane.

A method for performing hemodialysis within an artery, the method comprising:

• inserting a dialysis tube into an artery, the dialysis tube having an outer dialysis tube, an inner dialysis tube, and a dialysis membrane, the inner dialysis tube disposed within an intermediate cavity of the outer dialysis tube, wherein the inner dialysis tube has an inlet coupled to an import tube, an outlet coupled to an export tube, and an interior cavity, the inlet and the outlet disposed at the first end of the outer dialysis tube;
• driving dialysate solution through the import tube into the interior cavity of the inner dialysis tube;
• extracting excess fluid from blood flowing within the artery, the excess water flowing from the blood in the intermediate cavity, across the dialysis membrane, and into the dialysate solution in the interior cavity;
• and
• withdrawing the excess fluid and the dialysate solution from the inner dialysis tube to the export tube.
