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

This inventive concept discloses an improved system and method for assessing blood vessels, providing real-time visualization and decision support for medical professionals during procedures, thereby enhancing patient safety and treatment outcomes.

Background and Problem Solved

The original patent disclosed a system for evaluating blood vessels, but it had limitations in providing real-time visualization and decision support. The present inventive concept addresses these limitations by introducing a more advanced system that generates a 3D model of the vessel, enabling real-time visualization during medical procedures and providing decision support for medical treatment.

Detailed Description of the Inventive Concept

The enhanced system comprises a first instrument sized and shaped for introduction into the vessel, a processing system, and a visualization module or decision support module. The processing system obtains a pressure ratio and generates a 3D model of the vessel, which is then displayed in real-time by the visualization module to facilitate visualization of the vessel during medical procedures. The decision support module analyzes the 3D model to identify areas of high risk of vessel occlusion and provides real-time recommendations for medical treatment.

Novelty and Inventive Step

The new claims introduce the concept of real-time visualization and decision support, which is not present in the original patent. The inventive step lies in the integration of the visualization module or decision support module with the processing system, enabling medical professionals to make more informed decisions during procedures.

Alternative Embodiments and Variations

Alternative embodiments may include the use of different sensors or imaging modalities to obtain the pressure ratio, or the integration of the system with other medical devices, such as ultrasound or fluoroscopy machines. Variations may include the use of machine learning algorithms to improve the accuracy of the 3D model or the decision support module.

Potential Commercial Applications and Market

The enhanced vessel assessment system has significant commercial potential in the medical device industry, particularly in the fields of cardiology, radiology, and vascular surgery. The system's ability to provide real-time visualization and decision support can improve patient outcomes, reduce complications, and enhance the overall quality of care.
