Implantable human kidney replacement unit
First Claim
1. an implantable human kidney replacement unit comprising in combination:
- an outer housing;
a support frame mounted inside the housing;
a blood inlet port in said housing, located at one end of the housing;
a blood discharge port in said housing, spaced apart from the blood inlet port;
a urine waste discharge port in said housing, located at a generally lower end of the housing;
at least one arterial inlet tube for joining to a patient'"'"'s iliac or other major artery on one end and sealingly connecting to the blood inlet port;
at least one venous discharge tube connected to the blood discharge port at one end for joining to the patient'"'"'s iliac or other major vein on opposite end;
at least one urine discharge tube connected to the urine waste discharge port on one end for joining to the patient'"'"'s ureter at opposite end of said urine discharge tube;
a plurality of reverse osmosis filtration membranes located in the housing and support frame; and
a plurality of osmosis-diffusion membranes located in the housing and support frame.

Abstract
An implantable human kidney replacement unit. Fully functional self contained, providing patients with end stage renal disease the freedom of traveling and moving about normally. Replacing donor kidneys. Implanted in the flank with at least one inlet and outlet tube each, sutured to the iliac artery and vain, at least one urine tube to the ureter. The housing constructed of anti-coagulant bacteriostatic materials has a plurality of reverse-osmosis process chambers with semipemeable membranes through the unit, followed by osmosis-diffusion chambers and membranes. Blood from the artery enters the first of the chambers. Small molecules such as water, magnesium, sodium, potassium, calcium, urea etc. are extracted from the blood according to their weight in atomic mass units as blood wipes past the self-cleaning membrane cartridges in the chambers. Molecules are further separated and urea sent to the bladder with excess water and electrolytes. The remainder is channeled to at least one diffusion chamber and reabsorbed into the blood. The same process is repeated in the other chambers where selected larger molecules such as creatinine and phosphorus are excreted, and some diffused back into the blood.
