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. 11,857,172.

Summary of the Inventive Concept

A vascular closure system integrating AI, IoT, blockchain, and new materials to enhance deployment, safety, and customization, thereby revolutionizing vascular access hole closure.

Background and Problem Solved

The original patent's vascular closure device, while effective, has limitations in terms of optimal deployment, real-time feedback, and customization. The new inventive concept addresses these limitations by incorporating synergistic combinations of distinct technologies.

Detailed Description of the Inventive Concept

The vascular closure system comprises a vascular closure device, a machine learning module for predicting optimal deployment, a communication module for real-time feedback, IoT sensors for data collection, a blockchain module for deployment verification, and a 3D printing module for customizing the device with new materials. The system enables real-time adjustment of deployment based on AI analysis, ensuring optimal closure. The blockchain module ensures the integrity of the deployment process, while the 3D printing module allows for customization with enhanced biocompatibility materials.

Novelty and Inventive Step

The new claims introduce the novel combination of AI, IoT, blockchain, and new materials, which is not obvious from the original patent. The inventive step lies in the integration of these distinct technologies to create a more powerful and customizable vascular closure system.

Alternative Embodiments and Variations

Alternative embodiments may include variations in the machine learning algorithms, IoT sensor configurations, blockchain protocols, and 3D printing materials. Additionally, the system could be adapted for use in other medical applications, such as surgical site closure or tissue engineering.

Potential Commercial Applications and Market

The vascular closure system with synergistic combinations has significant commercial potential in the medical device industry, particularly in the fields of interventional cardiology, vascular surgery, and surgical robotics. The system's enhanced safety, customization, and efficiency features are likely to appeal to hospitals, medical centers, and research institutions.
