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. 11,857,694.

Summary of the Inventive Concept

A new generation of embolic particles integrated with distinct technologies such as AI, IoT, blockchain, and new materials to create a more powerful and effective system for occluding vascular defects and treating aneurysms.

Background and Problem Solved

The original patent described embolic particles with adjustable diameters for occluding vascular defects. However, these particles lacked the ability to adapt to individual patient needs, monitor treatment outcomes in real-time, and ensure secure data storage. The new inventive concept addresses these limitations by integrating the embolic particles with advanced technologies to create a more comprehensive and effective treatment system.

Detailed Description of the Inventive Concept

The synergistic embolic particle system comprises embolic particles configured to fit through a microcatheter and expand upon implantation. These particles are integrated with a machine learning algorithm to predict optimal particle size and delivery location, ensuring personalized treatment planning. The system also includes a flow diverting stent and a micro-sensor for real-time monitoring of aneurysm occlusion. Additionally, the system utilizes a blockchain-based data storage system for secure and transparent tracking of particle delivery and treatment outcomes. The system can be further expanded by integrating with IoT-enabled medical devices and using additive manufacturing to create customized particles with AI-powered recommendation systems.

Novelty and Inventive Step

The new claims introduce a novel combination of embolic particles with AI, IoT, blockchain, and new materials, which is not obvious from the original patent. The integration of these distinct technologies creates a more powerful and effective system for occluding vascular defects and treating aneurysms.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include integrating the embolic particles with other advanced technologies such as robotics, nanotechnology, or 3D printing. The system could also be adapted for use in other medical applications such as occluding luminal defects in the bile ducts, urethra, or vagina.

Potential Commercial Applications and Market

The synergistic embolic particle system has significant commercial potential in the medical device industry, particularly in the fields of interventional neuroradiology and cardiology. The system's ability to provide personalized treatment planning, real-time monitoring, and secure data storage makes it an attractive solution for hospitals and medical centers seeking to improve patient outcomes and reduce costs.
