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. 11,857,442.

Summary of the Inventive Concept

The inventive concept adapts stent systems for treating bifurcated vessels to specific, high-stakes environments, such as high-altitude, disaster relief, high-security, remote tropical, and extreme weather conditions, enhancing treatment outcomes and improving patient care.

Background and Problem Solved

The original patent for treating bifurcated vessels has limitations when applied to unique operational environments. This inventive concept addresses these limitations by developing specialized stent systems tailored to specific niche markets, ensuring effective treatment and minimizing risks.

Detailed Description of the Inventive Concept

The inventive concept comprises four specialized stent systems: 1) a high-altitude stent system with stents adapted for deployment above 8,000 feet, 2) a disaster relief stent system with a portable, debris-negotiating delivery system, 3) a high-security stent system with a secure communication module for remote monitoring, and 4) a tropical stent system with a heat-resistant catheter shaft and cooling system. Each system is designed to overcome the challenges posed by its respective environment, ensuring successful stent deployment and patient treatment.

Novelty and Inventive Step

The new claims introduce novel adaptations of stent systems for specific, high-stakes environments, which are not addressed by the original patent. The inventive step lies in the recognition of the need for specialized stent systems and the development of tailored solutions to overcome the unique challenges of each environment.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include stent systems adapted for other niche environments, such as space exploration or underwater operations. Variations could include the integration of additional sensors or communication modules to enhance treatment outcomes and patient monitoring.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the areas of cardiovascular treatment and emergency response. Target markets include hospitals, research institutions, and government agencies operating in high-stakes environments.

Field of Art

Medical device engineering, specifically interventional cardiology and vascular stent systems, involving complex catheter and stent deployment techniques for bifurcated vessel treatments

Person of Ordinary Skill (PHOSITA) Profile

A biomedical engineer or interventional cardiologist with advanced knowledge of medical device design, catheter mechanics, material science, and stent deployment strategies, typically holding a PhD or equivalent professional experience

Obviousness Rationale

A PHOSITA would recognize that the specialized stent systems represent predictable variations of existing bifurcation stenting techniques, merely adapting known stent deployment principles to specific environmental contexts. The core stenting methodology remains fundamentally unchanged, with environmental adaptations representing routine engineering modifications. The disclosed variations demonstrate standard problem-solving approaches within medical device engineering, applying known stent technologies to address specific operational challenges.
