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. 11,857,741.

Summary of the Inventive Concept

A next-generation endovascular aneurysm repair system that leverages advanced materials, sensors, and robotics to improve treatment outcomes, reduce procedure time, and enhance patient safety.

Background and Problem Solved

Current endovascular aneurysm repair (EVAR) and thoracic endovascular aneurysm repair (TEVAR) procedures are often challenging, time-consuming, and prone to human error. The original patent's looped wire design, while innovative, has limitations in terms of stent placement accuracy, vessel tortuosity, and adaptability to complex branch geometries. The new inventive concept addresses these limitations by integrating shape-memory alloy guidewires, real-time sensors, and AI-driven robotics to provide a more accurate, efficient, and personalized treatment approach.

Detailed Description of the Inventive Concept

The advanced endovascular aneurysm repair system comprises a shape-memory alloy guidewire with integrated sensors that detect blood vessel tortuosity and provide real-time feedback for optimal stent placement. The system also features a modular endograft design with interchangeable, 3D-printed stent modules that can be customized to fit individual patient anatomies and accommodate complex branch geometries. Additionally, the system incorporates a robotic-assisted endovascular platform with haptic feedback and AI-driven navigation to facilitate precise stent placement and minimize human error. Furthermore, the system utilizes bioabsorbable, nanofiber-based endografts that promote tissue ingrowth and remodeling, allowing for a more natural, long-term repair of aortic aneurysms.

Novelty and Inventive Step

The new claims introduce a paradigm shift in endovascular aneurysm repair by combining advanced materials, sensors, and robotics to achieve unprecedented levels of accuracy, efficiency, and personalization. The integration of shape-memory alloy guidewires, real-time sensors, and AI-driven robotics represents a significant departure from the original patent's looped wire design, offering a more comprehensive and effective solution for EVAR and TEVAR procedures.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of other advanced materials, such as nitinol or titanium alloys, or the incorporation of additional sensors, such as ultrasound or optical sensors, to further enhance stent placement accuracy. Variations of the modular endograft design could include the use of different 3D printing technologies or the integration of additional features, such as anti-microbial coatings or drug-eluting surfaces.

Potential Commercial Applications and Market

The advanced endovascular aneurysm repair system has significant commercial potential in the medical device industry, particularly in the areas of cardiovascular and vascular surgery. The system's ability to improve treatment outcomes, reduce procedure time, and enhance patient safety could lead to widespread adoption in hospitals and medical centers worldwide, resulting in a substantial market share and revenue growth.
