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

This inventive concept presents specialized stent graft devices tailored for specific, high-demand operational environments, including high-turbulence, extreme weather, high-security, and disaster relief scenarios, offering improved fluid flow and tissue ingrowth management.

Background and Problem Solved

The original patent disclosed implantable intraluminal devices, but these devices may not be suitable for unique operational environments. This inventive concept addresses the need for adaptable stent graft devices that can effectively manage fluid flow and tissue ingrowth in specialized settings.

Detailed Description of the Inventive Concept

The inventive concept comprises stent graft devices with flow channels disposed at the peripheral wall, adapted for fluid flow in high-turbulence environments, or designed to withstand extreme weather conditions. The devices can be deployed in bodily conduits with side branches, ensuring alignment of flow channels with the side branches. In high-security environments, the flow channels can be designed for secure fluid flow. During disaster relief efforts, the flow channels facilitate fluid flow in response to emergency situations.

Novelty and Inventive Step

The inventive concept's novelty lies in its adaptation of stent graft devices for niche environments, introducing specialized flow channels and device designs that address specific operational challenges. The inventive step is the recognition of the need for adaptable stent graft devices and the development of solutions that effectively manage fluid flow and tissue ingrowth in these environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include stent graft devices with adjustable flow channels, self-expanding stent grafts, or devices with integrated sensors for real-time monitoring. Variations could include devices designed for specific bodily conduits, such as coronary or peripheral arteries.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the areas of cardiovascular, neurovascular, and peripheral vascular interventions. The target market includes hospitals, clinics, and medical research institutions operating in high-demand environments.
