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. 11,857,245.

Summary of the Inventive Concept

An improved multi-channel RF ablation system that minimizes intermodulation distortion and optimizes ablation efficiency by generating control signals with frequencies within a predetermined range of the ablation signal frequency and adjusting their amplitude based on the subject's physiological response.

Background and Problem Solved

The original patent (U.S. Pat. No. 9,005,193) describes a multi-channel RF ablation method and apparatus, but it has limitations in terms of intermodulation distortion and ablation efficiency. The present inventive concept addresses these limitations by introducing a novel approach to control signal generation and amplitude adjustment, ensuring more efficient and safer ablation procedures.

Detailed Description of the Inventive Concept

The enhanced multi-channel RF ablation system comprises a generator for producing multiple ablation signals and respective control signals. Each control signal has a frequency within a predetermined range of the ablation signal frequency, and the control signals are amplitude-modulated to reduce intermodulation distortion. The system also includes a control unit that monitors the subject's physiological response and adjusts the amplitude of the control signals accordingly. This approach enables more precise and efficient ablation, reducing the risk of complications and improving treatment outcomes.

Novelty and Inventive Step

The inventive concept's novelty lies in the generation of control signals with frequencies within a predetermined range of the ablation signal frequency, and the adjustment of their amplitude based on the subject's physiological response. This approach is non-obvious compared to the original patent, as it introduces a new method for minimizing intermodulation distortion and optimizing ablation efficiency.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different frequency ranges for the control signals, implementing additional feedback mechanisms to adjust the control signal amplitude, or incorporating machine learning algorithms to optimize ablation efficiency. Variations of the system could be designed for specific medical applications, such as cardiac ablation or cancer treatment.

Potential Commercial Applications and Market

The enhanced multi-channel RF ablation system has significant commercial potential in the medical device industry, particularly in the areas of cardiac ablation and cancer treatment. The system's ability to minimize intermodulation distortion and optimize ablation efficiency could lead to improved treatment outcomes, reduced complications, and increased market share for companies adopting this technology.
