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

An improved electrohydraulic shockwave generator that optimizes electrode lifetime through dynamic voltage pulse rate adjustment, self-diagnostic capabilities, and redundant electrode configurations, ensuring enhanced safety, efficiency, and reliability in therapeutic shockwave applications.

Background and Problem Solved

The original patent disclosed an electrohydraulic shockwave generator with improved electrode lifetime, but it still faced limitations in terms of electrode degradation and failure. The new inventive concept addresses these limitations by introducing real-time electrode monitoring, dynamic voltage pulse rate adjustment, and redundant electrode configurations to ensure continuous operation and extend electrode lifetime.

Detailed Description of the Inventive Concept

The enhanced electrohydraulic shockwave generator comprises a housing defining a chamber and a shockwave outlet, 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 pulse-generation system is designed to optimize electrode lifetime by dynamically adjusting the voltage pulse rate based on electrode degradation, which is monitored in real-time. Additionally, the system includes a self-diagnostic module to detect electrode degradation and automatically adjust the voltage pulse rate. In another embodiment, the system features a redundant electrode configuration to ensure continuous operation in the event of electrode failure. This innovative approach enables the generator to operate efficiently and safely, while minimizing electrode replacement and downtime.

Novelty and Inventive Step

The new inventive concept introduces a novel approach to optimizing electrode lifetime through dynamic voltage pulse rate adjustment, self-diagnostic capabilities, and redundant electrode configurations. These features are not present in the original patent and provide a significant improvement in the safety, efficiency, and reliability of the electrohydraulic shockwave generator.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the pulse-generation system, such as different voltage pulse rates or waveforms, or alternative electrode configurations, such as different materials or geometries. Additionally, the self-diagnostic module could be integrated into the pulse-generation system or operate as a standalone component.

Potential Commercial Applications and Market

The enhanced electrohydraulic shockwave generator has significant commercial potential in the therapeutic shockwave market, particularly in applications such as orthopedic, urologic, and cardiovascular treatments. The improved safety, efficiency, and reliability of the generator make it an attractive solution for medical professionals and patients alike, offering a competitive advantage in the market.
