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. 11,857,413.

Summary of the Inventive Concept

A novel family of prosthetic heart valves tailored to address specific, underserved patient populations and unique operational environments, building upon the foundational stented prosthetic heart valve technology.

Background and Problem Solved

Conventional prosthetic heart valves often fail to cater to patients with rare heart defects, pediatric patients, or those requiring specialized solutions for high-security, disaster relief, or extreme weather conditions. The original patent's stented prosthetic heart valve, while innovative, has limitations in addressing these niche markets. This new inventive concept adapts the original technology to meet the distinct needs of these underserved populations.

Detailed Description of the Inventive Concept

The inventive concept encompasses a range of specialized prosthetic heart valves, each designed to address specific challenges. For pediatric patients, the valve features a stent frame with a diameter expandable from 10 mm to 20 mm, allowing for low-pressure environments. For patients with rare heart defects, the valve is deployed using a steerable catheter to navigate complex anatomical structures. In high-altitude environments, the valve incorporates a specialized coating to reduce thrombogenicity, while in low-oxygen conditions, the valve structure is adapted for optimal performance. Additionally, a radiation-resistant material is used in the stent frame for patients with a history of radiation therapy, and a specialized retrieval device is designed for malfunctioning valve removal.

Novelty and Inventive Step

The inventive concept's novelty lies in its tailored approach to addressing specific, niche markets, which the original patent did not contemplate. The new claims introduce non-obvious modifications to the original technology, including specialized coatings, materials, and deployment methods, to create a family of prosthetic heart valves that cater to unique patient populations and operational environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include prosthetic heart valves for patients with other rare conditions, such as those requiring implantation in non-standard anatomical locations. Variations could also involve integrating sensors or other diagnostic tools to monitor valve performance and patient health.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the areas of pediatric cardiology, rare heart defect treatment, and high-altitude or extreme environment medical care. The specialized prosthetic heart valves could be marketed to hospitals, medical research institutions, and government agencies involved in disaster relief and high-security operations.
