Summary of the Inventive Concept

A novel system integrating the patented Z stent cylinder with a braided stent and advanced technologies such as AI, IoT, blockchain, and new materials to create a more powerful system for treating venous diseases.

Background and Problem Solved

The original patent's integrated Z and Wallstent design has limitations in real-time monitoring, stent deployment optimization, and patient outcome tracking. The new inventive concept addresses these limitations by incorporating advanced technologies to create a more effective and efficient system.

Detailed Description of the Inventive Concept

The system comprises an integrated Z stent cylinder with a braided stent, embedded with micro-sensors for real-time monitoring of blood flow and pressure. A machine learning algorithm predicts stent failure, and a computer vision system optimizes stent deployment. The Z stent cylinder is coated with a bio-compatible material infused with anti-inflammatory agents, and a blockchain-based data management system tracks patient outcomes. The system also integrates an IoT-enabled sensor for remote monitoring of stent performance and an AI-powered predictive analytics module for identifying high-risk patients. In another embodiment, the Z stent cylinder is fabricated from a novel, shape-memory alloy, and a machine learning-based optimization algorithm is used for personalized stent design.

Novelty and Inventive Step

The new claims introduce the integration of advanced technologies such as AI, IoT, blockchain, and new materials with the patented Z stent cylinder and braided stent, providing a synergistic combination that is not obvious from the original patent.

Alternative Embodiments and Variations

Other embodiments of the inventive concept could include integrating the Z stent cylinder with other types of stents, using different materials or coatings, or incorporating additional sensors or analytics modules. The system could also be adapted for use in other medical applications, such as cardiovascular or neurological diseases.

Potential Commercial Applications and Market

The integrated Z and Wallstent system with advanced technologies has significant commercial potential in the medical device industry, particularly in the treatment of venous diseases. The system's advanced features and improved performance could attract a large market share and generate significant revenue.
