1. A dialysis device implantable in a patient for dialysis, comprising a filtration unit, the filtration unit comprising:
at least one dialysis chamber for containing and/or circulating dialysate;
at least one blood chamber for containing and/or circulating blood of the patient, disposed on at least one dialysis chamber and being in communication with the at least one dialysis chamber; and
at least one ultrafiltration membrane disposed between the at least one dialysis chamber and the at least one blood chamber such that the blood contained in the blood chamber is in contact with one surface of the at least one ultrafiltration membrane that faces the blood chamber, the dialysate fluid contained in the at least one dialysis chamber is in contact with another surface of the at least one ultrafiltration membrane that faces the at least one dialysis chamber, and the blood in the at least one blood chamber and the dialysate in the at least one dialysis chamber operably interact with each other for dialysis,
wherein each of the at least one dialysis chamber and the at least one blood chamber comprise at least one inlet for circulating fluid into and/or out of the at least one dialysis chamber and the at least one blood chamber.
