Enhanced Tissue Ablation System with Adaptive Pulse Shape Design and Real-time Monitoring

An improved tissue ablation system that incorporates adaptive pulse shape design, real-time monitoring, and optimized electrode configuration to enhance electroporation and electrolysis effects, resulting in more efficient and safer tissue ablation.

The original patent disclosed methods, systems, and apparatuses for tissue ablation using pulse shape designs. However, these designs had limitations in terms of optimizing electroporation and electrolysis effects, which can lead to inefficient and unsafe tissue ablation. The new inventive concept addresses these limitations by introducing adaptive pulse shape design, real-time monitoring, and optimized electrode configuration.

The new inventive concept comprises a pulse generator configured to deliver a pulse with an adaptive pulse shape design, which is adjusted in real-time based on tissue impedance measurements to optimize electroporation and electrolysis effects. The pulse shape design incorporates a high-frequency component to enhance electroporation and a low-frequency component to enhance electrolysis, thereby increasing the extent of tissue ablation. The system also includes a plurality of electrodes with varying geometries, which are configured to optimize the distribution of electrolytic products and electroporation effects within the targeted tissue. Real-time monitoring of tissue ablation is achieved using a combination of electrical impedance tomography and optical coherence tomography, which provides feedback to adjust the pulse shape design and electrode configuration in real-time to optimize tissue ablation.

The new claims introduce the concept of adaptive pulse shape design, real-time monitoring, and optimized electrode configuration, which are not present in the original patent. These features provide a significant improvement over the original patent by enabling real-time optimization of electroporation and electrolysis effects, resulting in more efficient and safer tissue ablation.

Alternative embodiments of the inventive concept could include using different types of electrodes, such as needle electrodes or surface electrodes, or incorporating additional sensors to monitor tissue ablation. Variations of the pulse shape design could also be explored, such as using different frequencies or amplitudes to optimize electroporation and electrolysis effects.

The enhanced tissue ablation system has significant commercial potential in the medical device industry, particularly in the areas of cancer treatment, cardiovascular disease, and neurosurgery. The system's ability to provide more efficient and safer tissue ablation could lead to improved patient outcomes and reduced healthcare costs.
