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. 11,857,208.

Summary of the Inventive Concept

The inventive concept integrates the patented syringe-type aspiration device with distinct technologies such as AI, IoT, blockchain, and new materials to create a more powerful system for aspirating from a body lumen, enhancing clot removal and improving patient outcomes.

Background and Problem Solved

The original patent addressed the need for effective aspiration systems for removing thrombotic blockages from blood vessels. However, the existing device had limitations in terms of maintaining vacuum force, detecting clots, and optimizing the aspiration process. The new inventive concept overcomes these limitations by incorporating advanced technologies to create a more efficient and effective system.

Detailed Description of the Inventive Concept

The synergistic aspiration system comprises a syringe-type aspiration device with a vacuum lock feature, an AI-powered clot detection module, an IoT-enabled pressure sensor, a blockchain-based secure data storage module, and a new material-based coating on the device's surface. The AI module identifies and locates clots in the blood vessel, while the IoT sensor provides real-time feedback to optimize the aspiration process. The blockchain module ensures secure tracking and verification of the procedure, and the new material coating enhances clot adhesion and facilitates more effective aspiration.

Novelty and Inventive Step

The new claims introduce a synergistic combination of distinct technologies, resulting in a more powerful and effective system for aspirating from a body lumen. The integration of AI, IoT, blockchain, and new materials provides a novel and non-obvious solution that significantly improves upon the original patent.

Alternative Embodiments and Variations

Alternative embodiments may include variations in the AI algorithm, IoT sensor configuration, blockchain implementation, and new material selection. Additionally, the inventive concept could be adapted for use in other medical procedures, such as laparoscopic or endoscopic surgeries.

Potential Commercial Applications and Market

The synergistic aspiration system has significant commercial potential in the medical device industry, particularly in the areas of cardiovascular and neurovascular interventions. The system's enhanced clot removal capabilities and improved patient outcomes make it an attractive solution for hospitals, clinics, and medical research institutions.
