Advanced Looped Wire System for Enhanced Endovascular Aneurysm Repair

An innovative looped wire system designed to improve the efficiency, safety, and accuracy of endovascular aneurysm repair procedures, addressing the limitations of current pre-cannulated endograft systems.

The original patent disclosed a pre-cannulated endograft system with looped wires, which, despite its advantages, still faces challenges in navigating tortuous blood vessels, ensuring proper endograft alignment, and minimizing wire wrapping risks. The new inventive concept addresses these limitations by introducing advanced features and functionalities to the looped wire system.

The advanced looped wire system comprises a variable stiffness segment, enabling smooth navigation through tortuous blood vessels. Additionally, the system features a built-in orientation indicator to facilitate accurate endograft alignment. A textured surface on the looped wire reduces wire-on-wire contact, minimizing the risk of wire wrapping. Furthermore, a detachable tip on the looped wire allows for easy release upon successful stent deployment. Integrated sensors in the looped wire provide real-time feedback on endograft positioning, ensuring precise deployment.

The new inventive concept's variable stiffness segment, built-in orientation indicator, textured surface, detachable tip, and integrated sensors introduce novel and non-obvious features that significantly improve the performance and safety of endovascular aneurysm repair procedures, distinguishing it from the original patent.

Alternative embodiments of the advanced looped wire system could include adjustable stiffness segments, modular orientation indicators, or surface coatings to further reduce wire-on-wire contact. Variations of the detachable tip could include different release mechanisms or materials. Additionally, the integrated sensors could be replaced with alternative feedback mechanisms, such as optical or electromagnetic sensors.

The advanced looped wire system has significant commercial potential in the medical device industry, particularly in the field of endovascular aneurysm repair. The system's improved performance, safety, and efficiency make it an attractive solution for hospitals, clinics, and medical professionals, potentially capturing a significant market share in the growing endovascular repair market.
