Abstract
A method for treating congestive heart failure (CHF) has been developed that restores kidney renal functions by artificially perfusion of at least one kidney. The kidney is perfused with the patient's blood or other suitable perfusion fluid. A catheter inserted into the aorta of the patient has a distal end that supplies the perfusion fluid into a renal artery of the patient. The catheter may be coupled to an implanted blood pump or to an external supply of perfusion pressure. The restoration of kidney function assists the heart by removing excess fluid, urine and toxin from the patient, and by normalizing the patient's renin-angiotensin system and other neurohormonal substances. The method is applicable to treat chronic and acute CHF.
