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. 11,857,407.

Summary of the Inventive Concept

A next-generation stent graft system that dynamically adapts to fluid flow changes, self-heals during deployment, and incorporates bio-absorbable materials for long-term native tissue growth, revolutionizing implantable intraluminal medical devices.

Background and Problem Solved

The original patent's stent graft device, while effective, has limitations in terms of adaptability, durability, and tissue integration. The new inventive concept addresses these limitations by introducing adaptive, self-healing, and bio-absorbable features that enhance device functionality and patient outcomes.

Detailed Description of the Inventive Concept

The new stent graft system comprises a primary conduit and one or more secondary conduits, featuring a selectively deployable, shape-memory material that enables the conduit to dynamically adapt to changes in fluid flow between the primary and secondary conduits. The system also incorporates a self-healing material integrated into the stent graft device, which repairs any damage incurred during deployment. Additionally, the system is modular and multi-component, allowing for independent deployment and interconnection of components to form a customized, patient-specific stent graft device. Furthermore, the device is designed with bio-absorbable materials that degrade over time, allowing for the growth of native tissue and eventual replacement of the device. The stent graft system also features a nanotechnology-enabled, self-cleaning surface that prevents biofilm formation and promotes long-term device functionality.

Novelty and Inventive Step

The new claims introduce a paradigm shift in stent graft technology by incorporating adaptive, self-healing, and bio-absorbable features, which are not present in the original patent. The combination of these features provides a novel and non-obvious solution to the limitations of traditional stent graft devices.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the shape-memory material, self-healing material, and bio-absorbable materials used. Additionally, the modular design could be adapted for use in different bodily conduits, such as coronary or peripheral arteries.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in the medical device industry, particularly in the fields of cardiovascular and peripheral vascular disease treatment. The device's adaptability, self-healing capabilities, and bio-absorbable features could revolutionize the treatment of complex vascular conditions, providing a competitive edge in the market and improving patient outcomes.
