Development of Ho: YAG laser-induced cavitational shock wave generator for endoscopic shock wave exposure
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.
