A method and devices for protecting kidneys from irreversible damage. The method is based on controlling or restricting blood flow through renal arteries in order to prevent kidney failure. The devices are delivered to a renal artery for restricting the flow of blood through the artery to the kidney. The devices may take the form of internal restrictors, such as an orifice, a venturi, a tapered coil, or a perforated sleeve that is inserted in a renal artery, or external devices such as an inflatable cuff or balloon, or a clamp that is placed around a renal artery. The improved method of the present invention includes means for delivering the internal devices to renal arteries by a percutaneous catheter system, or external devices by endoscopic devices or surgery. |
