Implantable human kidney replacement unit
First Claim
1. An implantable human kidney replacement unit for patients with end stage renal disease comprising in combination:
- a housing made of anti-coagulant bacteriostatic materials, formed integral with a main support frame, at least one arterial inlet tube for suturing to the patients iliac or other major artery on one end and sealingly connecting to said porting in said housing on opposite end. At least one venous discharge tube connected to the blood discharge port of said housing on first end and sutured to the patients iliac or other major vein on opposite end. At least one urine discharge tube connected to porting of said urine waste discharge passage in said housing on first end and sutured to the patients ureter at opposite end of said urine discharge tube.

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.

15. A extracorporeal or implantable human kidney replacement unit for patients with end stage renal disease, comprising in combination:
-
16. A housing having a main support frame means for sealingly supporting a plurality of semi permeable reverse osmosis membranes cartridges and osmosis diffusion membrane cartridges, said housing having porting, slits and chambers for channeling fluid to, through and from said membrane cartridges Said porting, slits and chambers being free of sharp corners and edges, to prevent fluid turbulence are arranged to force selected molecules from the blood as the blood passes by, not through the membranes in a self cleaning arrangement.
