Pulsed balloon and use method

Abstract

The invention relates to the field of medical appliances and particularly relates to a pulsed balloon and a use method. The pulsed balloon comprises a catheter main body, wherein a guide wire chamberis arranged in the catheter main body, a sealed tip is arranged at one end of the catheter main body, a first balloon is arranged at the sealed tip around the catheter main body, and an annular passage is formed on the first balloon around the catheter main body; and the first balloon is of a multilayer laminated structure and at least comprises first outer insulating layer, a first conducting layer and a first inner insulating layer sequentially from top to bottom. According to the pulsed balloon, a wave source between an anode and a cathode can be fully close to a treated calcification position, so as to achieve the aim of strengthening an impact wave effect; and along with strengthening of the impact wave effect, a relatively low voltage (less than or equal 1,000V) can be further selected or the number of times of discharging can be further reduced, so that the safety of surgical operation is guaranteed, meanwhile, the surgical operation time is shortened, and the time of short-timeischemia of a patient caused by balloon inflation is shortened.

Description

technical field [0001] The invention belongs to the field of medical devices, and more specifically, the invention relates to a pulse balloon and a usage method. 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. [0003] However, 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. Doctors call this narrowing aortic stenosis. [0004] Currently, there is no specific treatment for aortic calcification. General treatment includes monitoring for further development of heart disease. Cholesterol levels are also checked to determine the need for drug therapy to lower chol...

AI Technical Summary

Problems solved by technology

However, the anode and cathode in the balloon catheter are both wound on the inner tube, so the wave source cannot be close enough to the balloon wall, that is, it cannot be close enough to the calcification site, and the effect of the shock wave will be greatly damaged under the transmission of the electrolyte, such as To achieve the therapeutic effect, it is necessary to increase the number of discharges, or increase the voltage to enhance the shock wave effect to achieve the purpose of crushing calcification, resulting in a decrease in the safety of the use process

On the other hand, the structure is a liquid-filled structure with a single lumen. During the liquid-filling process, the air at the distal end of the balloon cannot be discharged, and when the electrolyte at the distal end cannot cover the electrodes, the distal end cannot generate effective shock waves. No effective treatment effect at the distal end can be guaranteed
