This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,212.

Summary of the Inventive Concept

A novel electrohydraulic shockwave generator apparatus and method that extends electrode lifetime through real-time voltage pulse rate adjustment, advanced cooling systems, and optimized pulse generation, ensuring improved therapeutic shock wave generation efficiency and safety.

Background and Problem Solved

The original patent disclosed an apparatus for generating therapeutic shock waves with improved electrode lifetime. However, it had limitations in terms of electrode lifetime, shock wave frequency, and amplitude control. The new inventive concept addresses these limitations by introducing advanced features that enable real-time electrode lifetime monitoring, adaptive voltage pulse rate adjustment, and optimized pulse generation, resulting in improved therapeutic shock wave generation efficiency and safety.

Detailed Description of the Inventive Concept

The enhanced electrohydraulic shockwave generator apparatus comprises a housing defining a chamber and a shockwave outlet, a liquid disposed in the chamber, a plurality of electrodes configured to be disposed in the chamber to define one or more spark gaps, and a pulse generation system configured to apply voltage pulses to the electrodes at a rate of between 10 Hz and 5 MHz. The apparatus further includes a sensor for monitoring the electrode lifetime, a control system for adjusting the voltage pulse rate and amplitude based on the monitored electrode lifetime, and a cooling system for maintaining the electrodes at a temperature below 50°C. The method for extending the lifetime of electrodes in an electrohydraulic shockwave generator involves monitoring the electrode lifetime using a sensor, adjusting the voltage pulse rate applied to the electrodes in real-time based on the monitored electrode lifetime, and controlling the pulse generation system to optimize the electrode lifetime while maintaining a desired shockwave frequency and amplitude.

Novelty and Inventive Step

The new inventive concept introduces the novel feature of real-time electrode lifetime monitoring and adaptive voltage pulse rate adjustment, which enables the optimization of electrode lifetime while maintaining a desired therapeutic shock wave generation efficiency and safety. This is a non-obvious improvement over the original patent, as it requires a sophisticated control system and advanced cooling mechanisms to achieve the desired results.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of sensors for electrode lifetime monitoring, varying the cooling system design, or incorporating additional features such as automated maintenance alerts or remote monitoring capabilities. Variations of the method could involve adjusting the pulse generation system's parameters based on different therapeutic applications or using machine learning algorithms to optimize electrode lifetime.

Potential Commercial Applications and Market

The enhanced electrohydraulic shockwave generator apparatus and method have significant commercial potential in the medical device industry, particularly in the areas of physical therapy, orthopedics, and sports medicine. The improved therapeutic shock wave generation efficiency and safety offered by the inventive concept could lead to increased adoption and market share in these industries.
