A kind of pulse balloon and using method

Abstract

The invention relates to the field of medical devices, in particular to a pulse balloon and a method for using it. A pulse balloon, comprising a catheter body, a guide wire cavity is arranged inside the catheter body, a sealing tip is arranged at one end of the catheter body, a first balloon is arranged around the catheter body at the sealing tip, and the first balloon is arranged around the catheter body at the sealing tip. A balloon surrounds the main body of the catheter to form an annular channel; the first balloon is a multi-layer composite structure, including at least a first outer insulating layer, a first conductive layer, and a first inner insulating layer from top to bottom. This product can make the wave source between the anode and the cathode sufficiently close to the calcification to be treated to achieve the purpose of enhancing the shock wave effect, and with the enhancement of the shock wave effect, you can further choose a lower voltage (less than or equal to 1000V) or Reducing the number of discharges not only ensures the safety of the operation, but also shortens the operation time and reduces the short-term ischemia time caused by the filling of the balloon.

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
