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. 11,857,211.

Summary of the Inventive Concept

The present invention relates to an improved vasculature obstruction removal system, addressing the limitations of existing systems by introducing a lubricating material-coated expandable member, vacuum pressure application, obstruction detection sensors, cooling systems, and ultrasonic wave dislodgement.

Background and Problem Solved

Existing vasculature obstruction removal systems often face issues with dislodgement, leading to potential complications. The present invention solves this problem by introducing enhancements that ensure secure removal, reduce friction, and prevent heat buildup.

Detailed Description of the Inventive Concept

The enhanced vasculature obstruction removal system comprises a guide catheter and an obstruction removal device with an expandable member coated with a lubricating material. This reduces friction during insertion and removal, ensuring smoother operation. The system also includes a sensor to detect the presence of an obstruction and automatically deploy the expandable member. Additionally, a vacuum pressure can be applied to the obstruction through the expandable member to secure it. A cooling system can be integrated to reduce heat generated during the removal process. Furthermore, ultrasonic waves can be used to dislodge the obstruction from the vasculature wall.

Novelty and Inventive Step

The new claims introduce non-obvious enhancements to the original patent, including the lubricating material-coated expandable member, vacuum pressure application, obstruction detection sensors, cooling systems, and ultrasonic wave dislodgement. These features provide a significant improvement over existing systems, ensuring secure and efficient vasculature obstruction removal.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the type of lubricating material, adjusting the vacuum pressure levels, or integrating additional sensors to detect obstruction characteristics. Variations could also include using different materials for the expandable member or incorporating additional features to enhance system safety.

Potential Commercial Applications and Market

The enhanced vasculature obstruction removal system has significant commercial potential in the medical device industry, particularly in the fields of interventional cardiology and neurology. The system's improved safety and efficiency features make it an attractive solution for hospitals and medical centers.
