Abstract

An apparatus for ablating deposits along the blood vessel of human and animals is disclosed. The apparatus has an extracting and pressurizing unit for extracting blood from a supply vessel and pressurizing it plus a downstream delivering and injecting unit for delivering and injecting the filtered and pressurized source blood into a blood vessel under treatment. Besides inducing a blood circulation and having ablation devices like ultrasound and RF heating, the apparatus ablates the deposits from a nearby portion of the vessel. The characteristics of selective ablation and self-termination make the proposed apparatus safe and effective in treating early-stage atherosclerosis. A DC discharging device can be included to neutralize excess surface charge generation on the wounded healthy tissues following ablation for disinfection and anti-inflammation. Placement of the blood extracting point just downstream of the blood injecting point insures thorough collection and removal of blood-clogging plaque and calcification fragments.

Description

technical field [0001] The present invention relates to a medical device, and more particularly to a new device for cleaning and removing undesirable deposits from the wall of an inner blood vessel. Background technique [0002] Atherosclerosis, (or arteriosclerosis), is usually associated with a radical narrowing of the inner diameter of arteries through the degenerative accumulation of long-term deposits or fatty substances such as cholesterol on the inner lining of the arterial wall. In fact, the physiological process that accompanies arteriosclerosis is very complex, including a self-healing mechanism of the human or animal body that tries to reduce a kind of arterial blockage medically known as arterial stenosis. Here, the self-healing mechanism works by expanding the diameter of the artery outwards or a process medically known as "remodeling". The constituent molecules of these long-term deposits, called atheromas, include microphagocytes, cellular debris of dead and ...
