Problems solved by technology

During the conduction of high-voltage electricity through the electrolyte, part of the high-voltage electricity will break down the thin wall, and part of the high-voltage electricity will appear on the outermost side of the balloon. The high-voltage electricity will act on the patient's blood vessels and cause heart rate disturbance.

Abstract

The invention relates to the field of medical devices, and more specifically, the invention relates to a pulse balloon and its application. The impulse balloon includes a balloon body and an inner tube; the balloon body includes an insulating layer and a balloon wall. An insulating layer is set on the balloon body. When the balloon is working, the balloon body is filled with electrolyte, so that the electrodes emit high-pulse piezoelectricity to generate pulses, and the balloon vibrates along with the propagation of the electrolyte, so that most of the electric energy is converted into The mechanical energy breaks down the calcified area of ​​the blood vessel, and the residual high voltage is blocked by the insulating layer, which avoids the conduction of the high voltage on the surface of the balloon and limits the excess high voltage at the pulse source. The use of the balloon body with an insulating layer can prevent excess electricity from being conducted to the pacemaker, signal conduction area, etc., so that the patient's heart rate can be maintained in a relatively stable state. For patients with severe calcification, the discharge voltage and discharge frequency can be increased to avoid damage to the human body while improving the effectiveness of the operation.

Description

technical field [0001] The invention relates to the field of medical devices, and more specifically, the invention relates to a pulse balloon and its application. Background technique [0002] Aortic calcification, also called aortic sclerosis, is the buildup of calcium deposits on the aortic valve in the heart. This often results in a heart murmur, which can be easily heard with a stethoscope placed over the heart. However, aortic calcification usually does not significantly affect aortic valve function. But in some cases, calcium deposits thicken and narrow the opening in the aortic valve. This reduces blood flow through the valve, causing chest pain or a heart attack. This narrowing is called aortic stenosis. [0003] The current method for reducing calcification is to apply shock waves to the calcified area of ​​the valve to promote cracking and / or break up the calcium deposits, thereby softening and / or loosening and / or removing the calcium deposits that have hardened...
