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 innovative stent system combining the benefits of Z stents and Wallstents, integrated with AI-powered monitoring, IoT-enabled sensors, and blockchain-based data storage to provide enhanced patient outcomes and improved healthcare management.

Background and Problem Solved

The original patent's Integrated Z and Wallstent addressed limitations in iliac vein stenting, but it lacked advanced monitoring and data management capabilities. This new inventive concept solves the problem by integrating cutting-edge technologies to provide real-time monitoring, secure data storage, and predictive analytics, enabling healthcare professionals to make informed decisions and improve patient care.

Detailed Description of the Inventive Concept

The integrated system comprises an expandable Z stent cylinder attached to a Wallstent using a laser weld, synthetic fiber suture, or flexible metal braided suture. The system is equipped with an AI-powered monitoring module for tracking stent performance, detecting potential complications, and providing personalized recommendations. Additionally, an IoT-enabled sensor monitors stent expansion and compression in real-time, while a blockchain-based data storage module ensures secure and transparent patient data management. The system can be deployed near the iliac-caval junction and is suitable for treating chronic venous disease.

Novelty and Inventive Step

The new claims introduce the novel combination of the Integrated Z and Wallstent with AI, IoT, and blockchain technologies, providing a synergistic system that enhances patient outcomes, improves healthcare management, and offers a unique value proposition. The inventive step lies in the integration of these distinct technologies to create a more powerful and effective stent system.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different attachment methods, varying stent geometries, or the integration of additional sensors or monitoring modules. Variations of the system could be designed for use in different vascular regions or for treating various medical conditions.

Potential Commercial Applications and Market

The integrated Z and Wallstent system with AI, IoT, and blockchain has significant commercial potential in the medical device industry, particularly in the vascular stent market. The system's advanced features and capabilities make it an attractive solution for healthcare providers, medical device manufacturers, and patients seeking improved outcomes and more efficient healthcare management.
