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

This inventive concept adapts the original looped wire technology for advanced stent grafts to cater to specific, high-stakes environments, such as high-security needs, disaster relief, or extreme weather conditions.

Background and Problem Solved

The original patent disclosed a pre-cannulated endograft system utilizing looped wires for endovascular aneurysm repair. However, these systems may not be suitable for high-risk or specialized scenarios, where enhanced security, rapid deployment, or environmental resilience are crucial. The present inventive concept addresses these limitations by introducing specialized looped wire designs and configurations tailored to these niche applications.

Detailed Description of the Inventive Concept

The inventive concept encompasses five distinct variations of the original looped wire technology: (1) a high-security stent grafting system featuring enhanced encryption for secure data transmission; (2) a rapid stent deployment method utilizing a redundant wire configuration for emergency response situations; (3) a self-lubricating and reinforced looped wire design for stent grafting in extreme weather conditions; (4) a modular endograft system with interchangeable looped wire modules for disaster relief scenarios; and (5) a stent grafting system incorporating a looped wire with integrated sensing technology for remote or isolated environments. Each variation is designed to address specific challenges and requirements in these specialized contexts.

Novelty and Inventive Step

The inventive concept's novelty lies in its adaptation of the original looped wire technology to address specific high-stakes environments, introducing new features and configurations that enhance security, speed, and resilience. The inventive step resides in the identification of these niche applications and the development of tailored solutions that overcome the limitations of the original patent.

Alternative Embodiments and Variations

Other embodiments of the inventive concept could include looped wires with integrated sensors for real-time procedural monitoring, specialized coatings for improved biocompatibility, or modular designs enabling on-site customization for unique patient anatomies.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the areas of high-security stent grafting, emergency response, and disaster relief. Target markets may include government agencies, healthcare providers, and medical device manufacturers operating in these specialized fields.
