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. 11,857,444.

Summary of the Inventive Concept

The present inventive concept integrates balloon expandable endoprostheses with advanced technologies such as AI, IoT, blockchain, and nanomaterials to create a new generation of intelligent endoprosthesis systems that can optimize deployment, enhance biocompatibility, and provide real-time feedback for improved patient outcomes.

Background and Problem Solved

The original balloon expandable endoprosthesis patent disclosed a system for treating vasculature, but it had limitations in terms of deployment precision, biocompatibility, and post-procedure monitoring. The present inventive concept addresses these limitations by synergistically combining the original endoprosthesis with advanced technologies to create a more powerful and effective system.

Detailed Description of the Inventive Concept

The inventive concept comprises a balloon expandable endoprosthesis integrated with a machine learning algorithm that predicts optimal deployment configurations based on patient-specific vasculature data. The system also includes a blockchain-secured IoT sensor network that provides real-time feedback for precise placement and minimizes procedural complications. Additionally, the stent-graft surface is modified with a nanomaterial to enhance biocompatibility and reduce restenosis, and an AI-powered sensor monitors device performance and detects potential failures. The system can also be integrated with a wearable device that analyzes patient-specific data and provides personalized recommendations for device deployment and post-procedure care.

Novelty and Inventive Step

The new claims introduce a synergistic combination of advanced technologies with the original balloon expandable endoprosthesis, resulting in a new and non-obvious system that provides significant improvements over the original patent. The integration of AI, IoT, blockchain, and nanomaterials creates a novel and inventive system that is not anticipated by the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include different AI algorithms, IoT sensor configurations, or nanomaterials. Additionally, the system could be adapted for use in other medical applications, such as cardiovascular or neurological treatments.

Potential Commercial Applications and Market

The intelligent endoprosthesis system has significant commercial potential in the medical device industry, particularly in the areas of cardiovascular and vascular treatments. The system's ability to optimize deployment, enhance biocompatibility, and provide real-time feedback could lead to improved patient outcomes, reduced complications, and increased market share.
