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. 11,857,440.

Summary of the Inventive Concept

An improved stent system combining a modified Z stent with enhanced durability and a braided stent with reinforced exterior sleeve, offering enhanced compressibility resistance, customized fit, and adaptability to different venous system locations.

Background and Problem Solved

The original Integrated Z and Wallstent patent has limitations in terms of durability, compressibility, and adaptability. The new inventive concept addresses these limitations by introducing enhanced wire thickness, adjustable strut length, variable diameter, and textured surface, providing a more efficient and effective solution for treating chronic venous disease.

Detailed Description of the Inventive Concept

The Enhanced Integrated Z and Wallstent System comprises a modified Z stent with thicker wire for improved durability, fixedly attached to a braided stent with a reinforced exterior sleeve for enhanced compressibility resistance. The system allows for adjustable strut length for customized fit and variable diameter for adaptability to different venous system locations. The braided stent features a tapered end for smooth navigation through the iliac-caval junction and a textured surface for enhanced biocompatibility. Additionally, the system can be integrated with a built-in pressure sensor for real-time monitoring of stent expansion and compression.

Novelty and Inventive Step

The new claims introduce novel features such as enhanced wire thickness, adjustable strut length, variable diameter, and textured surface, which are not present in the original patent. These features provide a non-obvious solution to the limitations of the original patent, offering improved durability, compressibility resistance, and adaptability.

Alternative Embodiments and Variations

Alternative embodiments of the Enhanced Integrated Z and Wallstent System could include different wire materials, strut patterns, or braided stent configurations. Variations could also include different sizes, shapes, or surface treatments to accommodate various venous system locations and patient needs.

Potential Commercial Applications and Market

The Enhanced Integrated Z and Wallstent System has significant commercial potential in the medical device industry, particularly in the treatment of chronic venous disease. The system's improved durability, compressibility resistance, and adaptability make it an attractive solution for patients and healthcare providers, offering a competitive advantage in the market.
