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. 11,857,244.

Summary of the Inventive Concept

The inventive concept discloses advanced tissue ablation systems and methods that improve upon the existing pulse shape designs by incorporating real-time feedback, adaptive pulse adjustment, and enhanced safety features.

Background and Problem Solved

The original patent, 'Methods, systems, and apparatuses for tissue ablation using pulse shape designs,' provides a foundation for minimally invasive tissue ablation using electrolysis. However, the existing approach has limitations, including the inability to adapt to real-time changes in the treatment site and the potential for muscle contractions and electric discharge. The new inventive concept addresses these limitations by introducing advanced features that enhance the safety, efficiency, and effectiveness of tissue ablation procedures.

Detailed Description of the Inventive Concept

The new inventive concept comprises a system for tissue ablation that includes a pulse generator, a sensor, and a cooling system. The pulse generator is configured to deliver pulses with exponential decay falling edges, which are adapted to adjust in real-time based on feedback from the sensor monitoring the treatment site. The cooling system reduces the temperature of the treatment site during pulse delivery, minimizing the risk of thermal damage. Additionally, the system can apply counter-stimulation to reduce muscle contractions. The inventive concept also encompasses methods for optimizing tissue ablation, including delivering a series of pulses and adjusting the magnitude and duration based on the response of the treatment site. Furthermore, the system enables real-time monitoring of tissue ablation, providing feedback to the pulse generator to ensure optimal treatment outcomes.

Novelty and Inventive Step

The new inventive concept introduces significant advancements over the original patent, including the incorporation of real-time feedback, adaptive pulse adjustment, and enhanced safety features. These innovations provide a substantial improvement in the safety, efficiency, and effectiveness of tissue ablation procedures, thereby overcoming the limitations of the existing approach.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include different pulse shapes, sensor types, and cooling systems. Additionally, the system could be integrated with other medical devices, such as imaging systems, to enhance treatment outcomes. Variations of the method may include different pulse sequences, frequencies, and amplitudes to accommodate various tissue types and treatment goals.

Potential Commercial Applications and Market

The enhanced tissue ablation systems and methods have significant commercial potential in the medical device industry, particularly in the areas of cancer treatment, cardiovascular disease, and orthopedic surgery. The target market includes hospitals, clinics, and medical research institutions, with potential for widespread adoption and revenue growth.
