Description

A Pulse Balloon with Capacitor and Its Application

technical field

The present invention relates to the field of medical devices, and more particularly, to a pulse balloon with a capacitor and an application thereof.

Background technique

Aortic calcification, also known as aortic stiffness, is the accumulation of calcium deposits on the aortic valve in the heart. Aortic calcification can have a very serious impact on the health of the human body.

Currently, aortic calcification is mainly treated clinically by puncturing or crushing the calcified area. For example, in the technical solution of the patent number CN104582597A, a plurality of pulsed high-voltage cathodes and anodes are distributed on the inner tube of the balloon, and the pulses during the discharge of the cathodes and anodes will drive the vibration of the electrolyte to cause the inner wall of the balloon to physically vibrate, resulting in The physical shock of the blood vessel counteracts the calcified area of the blood vessel to achieve the purpose of penetrating or shattering the calcified area. In the technical scheme of the patent number CN 109223100 A, the balloon is filled with electrolyte, which is re-discharged through a shock wave transmitter, thereby driving the electrolyte to vibrate, and the electrolyte vibrates to cause vibration of the balloon wall to shatter the calcified area.
