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. 11,857,296.

Summary of the Inventive Concept

The present disclosure relates to an enhanced vessel assessment system that leverages machine learning, advanced analytics, and real-time visualization to improve the accuracy and efficiency of vessel evaluation, particularly in the context of biological vessels such as human blood vessels.

Background and Problem Solved

The original patent disclosed a system for evaluating blood vessels, but it had limitations in terms of predicting stenosis risk, providing treatment recommendations, and tracking changes in pressure ratios over time. The present inventive concept addresses these limitations by integrating machine learning, advanced analytics, and real-time visualization to provide a more comprehensive and accurate vessel assessment.

Detailed Description of the Inventive Concept

The enhanced vessel assessment system comprises a first instrument sized and shaped for introduction into the vessel, a processing system in communication with the first instrument, and a machine learning module to predict a risk of stenosis based on the pressure ratio. The system generates a three-dimensional model of the vessel and determines a pressure ratio based on the model. The system further comprises a user interface to display the recommendation for treatment based on the pressure ratio. Additionally, the system tracks changes in the pressure ratio over time and provides a warning signal if the pressure ratio exceeds a predetermined threshold value.

Novelty and Inventive Step

The present inventive concept introduces the novel combination of machine learning, advanced analytics, and real-time visualization to improve the accuracy and efficiency of vessel evaluation. The integration of these components enables the system to predict stenosis risk, provide treatment recommendations, and track changes in pressure ratios over time, which are not possible with the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different machine learning algorithms, the integration of additional data sources such as patient history or medical imaging data, or the development of specialized instruments for specific vessel types. Variations of the system could also be designed for use in different medical specialties or for evaluating vessels in non-human subjects.

Potential Commercial Applications and Market

The enhanced vessel assessment system has significant commercial potential in the medical device industry, particularly in the areas of cardiovascular disease diagnosis and treatment. The system could be marketed to hospitals, clinics, and medical research institutions, and could also be used in conjunction with other medical imaging technologies to provide a more comprehensive understanding of vessel health.
