AI Technical Summary

Technical Problem

Conventional angioplasty methods struggle with random shock wave discharge positions, leading to dispersed and unfocused shock waves that are difficult to target calcified lesions effectively.

Method used

A shock wave electrode assembly with a flared cavity structure and adjustable directionality, featuring an inner electrode, outer electrode, and insulating layer, which focuses and intensifies shock waves for targeted treatment of calcified lesions.

Benefits of technology

The flared cavity design reduces shock wave dispersion, increases intensity, and allows directional control, enabling effective and targeted treatment of calcified lesions in blood vessels.

Abstract

The shock wave electrode assembly 100 and the balloon catheter device 300 include the shock wave electrode assembly 100. The shock wave electrode assembly 100 includes an inner electrode 110, an outer electrode 130, and an insulating layer 120 located between the inner electrode 110 and the outer electrode 130. A first hole 112 is provided in the inner electrode 110, a second hole 122 is provided in the insulating layer 120, and a third hole 132 is provided in the outer electrode 130. The diameter of the second hole 122 is equal to or larger than the diameter of the first hole 112, and the diameter of the third hole 132 is equal to or larger than the diameter of the second hole 122. The first hole 112, the second hole 122, and the third hole 132 are sequentially connected to form a cavity 140.
