Summary of the Inventive Concept

A next-generation tissue ablation and assessment system that integrates multi-modal antennas, machine learning algorithms, and personalized treatment planning to enable real-time monitoring, improved lesion formation, and enhanced patient outcomes.

Background and Problem Solved

The original patent described a system for tissue ablation and assessment using RF/microwave antennas. However, this system has limitations in terms of real-time monitoring, lesion formation, and personalized treatment. The new inventive concept addresses these limitations by introducing advanced technologies and integrating them into a comprehensive system.

Detailed Description of the Inventive Concept

The advanced tissue ablation and assessment system consists of a multi-modal antenna capable of transmitting and receiving electromagnetic radiation in a wide frequency range, including RF, microwave, and millimeter-wave frequencies. This enables real-time monitoring of ablation lesions and tissue-electrode contact during a procedure. The system also incorporates a machine learning-based algorithm that integrates S parameter measurements, endocardial potential, and ablation energy data to predict tissue-electrode contact and lesion progression in real-time. Additionally, the system features a microwave ablation catheter with a metamaterial-based antenna electrode that enables enhanced tissue heating and improved lesion formation, while minimizing thermal damage to surrounding tissue. Furthermore, the system includes a computational model for personalized ablation treatment planning, simulating the electromagnetic and thermal properties of biological tissue and optimizing ablation energy delivery based on individual patient anatomy and tissue characteristics. Finally, the system can be used in conjunction with a non-invasive tissue assessment system utilizing a wearable, patch-based antenna array to monitor tissue health and detect early signs of disease or injury.

Novelty and Inventive Step

The new inventive concept introduces a paradigm shift in tissue ablation and assessment by integrating advanced technologies, such as multi-modal antennas, machine learning algorithms, and personalized treatment planning. The combination of these technologies enables real-time monitoring, improved lesion formation, and enhanced patient outcomes, which are not achievable with the original patent's system.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of antennas, such as phased arrays or nano-antennas, or the integration of additional sensors, such as temperature or impedance sensors, to further enhance the system's capabilities. Variations of the system could also include different computational models or machine learning algorithms to optimize ablation energy delivery.

Potential Commercial Applications and Market

The advanced tissue ablation and assessment system has significant commercial potential in the medical device industry, particularly in the fields of cardiology, oncology, and neurology. The system's ability to enable real-time monitoring, improved lesion formation, and enhanced patient outcomes could lead to increased adoption and market share in these industries.
