Abstract

Recently, the application of shock waves in medicine has been extended to the treatment for more delicate, localized, and deeper lesions. Therefore, it is now obligatory to develop a specialized shock wave generator that is suitable for those purpses, with the ability to be deployed by endoscope or catheter.

We have developed a shock wave generator by operating pulsed Ho: YAG laser. The present device is remarkable in that it is possible to expose the center of the shock wave to target tissue in a localized area without significant thermal damage, it should be possible to apply this novel shock wave generator to catheters or endoscopes, for clinical use.
