Patent ID: 7666131

Claim:
A peri-arterial blood flow booster apparatus, for comprising: a pressure-applying device comprising: a restrainer envelope having an upstream end and a downstream end, and an interior surface defining an interior for receiving a blood vessel and a protrusion fixedly disposed on the interior surface; and a balloon disposed in the interior of the restrainer envelope for placing alongside a portion of the blood vessel, having two or more portions comprising an upstream portion disposed in the restrainer envelope interior extending from said protrusion towards the upstream end and a downstream portion disposed in the interior extending from said protrusion towards the downstream end, and a control console comprising an inflating unit for rapidly inflating and deflating the balloon, the inflating unit being connected to the balloon, sensing means for sensing electrocardiograph signals of a the patient, and a control unit for controlling the inflating unit in correlation with the electrocardiograph signals detected by the sensing means; wherein the downstream portion of the balloon extends further downstream from the protrusion than the upstream portion extends upstream from the protrusion such that upon inflation of the upstream portion blood backflow is prevented, and upon inflation of the downstream portion blood is forced to flow downstream.
