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. 11,857,417.

Summary of the Inventive Concept

The inventive concept disclosed herein adapts the original leaflet support design for cardiac implants to cater to specific, niche markets and operational environments, such as high-altitude, disaster relief, pediatric, extreme cold weather, and customized heart valve repair.

Background and Problem Solved

The original leaflet support patent addresses the issue of dilation of the annulus of a heart valve, which prevents the valve leaflets from fully coapting. However, the original design may not be suitable for unique operational environments or specific patient populations. This inventive concept solves the problem by providing specialized variations of the leaflet support to accommodate these niche requirements.

Detailed Description of the Inventive Concept

The inventive concept comprises a range of adaptive leaflet supports, each designed to address specific challenges. For high-altitude environments, the leaflet support features a reinforced frame to withstand increased pressure and reduced oxygen levels. For disaster relief areas, the leaflet support is designed to be compact and lightweight for ease of transportation. Pediatric heart valve repair is facilitated by a smaller-diameter leaflet support with a specialized cell pattern. Extreme cold weather environments are accommodated by a leaflet support with a frame adapted to withstand sub-zero temperatures and ice formation. Additionally, a method for customizing a leaflet support using advanced imaging and 3D printing techniques is disclosed, enabling bespoke leaflet supports with optimized cell patterns and frame geometry for individual patients.

Novelty and Inventive Step

The new claims provide a novel and non-obvious solution by adapting the original leaflet support design to cater to specific, niche markets and operational environments. The inventive concept's unique features, such as the reinforced frame for high-altitude environments and the compact design for disaster relief areas, distinguish it from the original patent and provide a significant improvement over the prior art.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include leaflet supports with adjustable frames, modular components for ease of assembly, or integrated sensors for real-time monitoring. Variations may also include leaflet supports designed for other extreme environments, such as high-radiation areas or extreme humidity.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the cardiac implant industry, particularly in the areas of specialized heart valve repair and niche market applications. Target industries may include medical device manufacturers, cardiac implant providers, and specialized healthcare services.
