Problems solved by technology

However, there is a problem with this method that the electric field is directly applied inside the liquid, which requires a high electric field strength and a large current output to generate shock waves of sufficient strength.
Once the balloon is damaged and leaks, high voltage and strong current will pass through the human body, which will cause serious electric shock accidents and even endanger the lives of patients and medical staff
In addition, high voltage and high current output will also cause excessive electrothermal conversion and energy release, which puts more stringent requirements on the design of catheters

Abstract

The invention relates to a micropore-induced shock wave balloon catheter and system. The system is composed of electric field generating equipment and the shock wave balloon catheter; the electric field generating equipment comprises a man-machine interaction module, a control module, a power module and a high-voltage pulse output module; the electric field generating equipment is electrically connected with the shock wave balloon catheter; the shock wave balloon catheter comprises a long and thin component extending in the axial direction, a working balloon body arranged at the far end of the long and thin component, a wire and a liquid injection pipe which are arranged in a cavity of the long and thin component, an electric field generating mechanism arranged in the working balloon body, and a micropore-induced shock wave generating device wrapping the electric field generating mechanism; the electric field generating mechanism is electrically connected with the high-voltage pulse output module through a wire; a micropore mechanism penetrating through the wall of the micropore-induced shock wave generating device is arranged on the micropore-induced shock wave generating device; and the micropore mechanism can prevent liquid from entering through the surface tension of the micropore mechanism, so that the micropore-induced shock wave generating device can isolate the electric field generating mechanism from liquid flowing into the working balloon body.

Description

Technical field [0001] The present application belongs to the field of minimally invasive treatment, applied in particular to a treatment of vascular calcified lesions induced shock microporous balloon catheters and systems. Background technique [0002] With the improvement of living standards and the increasing aging population, the incidence of vascular disease increasing every year. Development of vascular disease such that the vessel wall plaque evolving into calcium deposition, so that the narrowing of the arteries, restricting blood flow. When a blood vessel calcification, conventional practice is to use major conventional balloon for dilatation, stenting, or balloon plaques be employed peeling peeling. However, these treatments have obvious defects, often accompanied by vascular damage and complications. Such as balloon angioplasty and stenting procedure will produce intimal tear, which often results in vascular endothelial proliferation, resulting in the risk of restenos...
