Abstract: A method for treating congestive heart failure (CHF) has been developed that restores kidney renal functions by artificial vasodilation of at least one kidney. A vasodilator drug is locally delivered to the kidney via a kidney perfusion catheter. The drug can be mixed with the patient's blood, saline or other suitable solvent and the mixture directly applied to the kidney through the catheter. 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.

Abstract: This is an implantable device intended generally for forming an anastomosis between a lumen of the body and an intersecting graft lumen. The device may be configured to form an anastomosis which is entirely lined with live tissue, or it may be configured to form an anastomosis with synthetic material defining at least a portion of one of the intersecting lumens.
