Description

Ultrasonic balloon catheter system for cardiovascular lithotripsy

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to ultrasonic wave sacculus pipe system for cardiovascular rubble.

Background

With the aging of the population and the influence of factors such as environment, diet and living habits, the number of people suffering from vascular calcification and/or valvular calcification is increasing year by year. When a vessel becomes calcified and needs to be opened or a slightly calcified membrane needs to be repaired, it is conventional practice to pre-expand the vessel with an inflated balloon. This usually requires a significant amount of pressure, and the inflated balloon is gradually expanded under internal pressure until the pressure within the balloon causes the calcified lesion to rupture or burst, which may also cause damage to the vessel.

The foreign SHOCKWAVE MEDICAL company applies the technique of electro-hydraulic lithotripsy to angioplasty or valvular calcification. The basic principle is that certain voltage is utilized to generate bubbles in a balloon filled with liquid, the bubbles collapse in a very short time to generate shock waves, and therefore the purpose of crushing stones and calcifying lesion tissues is achieved. This co-pending patent application No. CN104519809A discloses an impact loblasty with multiple balloons. This patent describes a shock wave apparatus and method for calcified heart valve therapy. One variation of the shock wave device includes three balloons, each of which is sized and shaped to fit within a concave portion of the valve cusps when the balloon is inflated with a liquid. Each balloon is individually and/or independently controllable. A method of treating a calcified heart valve using a shock wave device includes advancing the shock wave device to contact the heart valve, wherein the shock wave device has one or more balloons and a shock wave source in each balloon, the method further including inflating the one or more balloons with a liquid such that the balloons are disposed within a concave portion of a valve cusp, and activating the shock wave source. One problem with this approach in treating valve calcification is that the direction of impact is uniform, resulting in a continuous impact in one direction and little or no impact in other directions; another problem is that once the balloon is ruptured, a high voltage is applied to the human body, causing the human body to get an electric shock. Another patent, CN104582621A, discloses a low profile electrode for use in an angioplasty shock waveguide, which also suffers from the above-mentioned problems.
