Summary of the Inventive Concept

An improved clot retrieval device that incorporates a clot-sensing mechanism and adaptive radial force control to ensure efficient and safe clot removal from blood vessels, addressing the limitations of existing devices.

Background and Problem Solved

The original patent for a clot retrieval device has limitations in effectively engaging and removing clots from blood vessels. The device's radial force exerted by the clot embedding cells may not be optimal for various clot properties, leading to inefficient or unsafe clot retrieval. This new inventive concept addresses these limitations by introducing a clot-sensing mechanism that detects clot properties and adjusts the radial force accordingly, enabling precise control over the clot retrieval process.

Detailed Description of the Inventive Concept

The enhanced clot retrieval device comprises an expandable structure with a constrained delivery configuration, an expanded clot engaging deployed configuration, and an at least partially constrained clot pinching configuration. The device further includes a clot-sensing mechanism, such as a pressure sensor, that provides real-time feedback to the operator. This feedback enables the operator to adjust the radial force exerted by the clot embedding cells to optimize clot retrieval based on clot properties and vessel anatomy. The device may also include a control unit with a predictive algorithm that anticipates clot behavior and adjusts the radial force proactively, reducing the risk of clot fragmentation or embolization.

Novelty and Inventive Step

The new inventive concept introduces the clot-sensing mechanism and adaptive radial force control, which are not present in the original patent. This combination of features enables real-time feedback and precise control over the clot retrieval process, making the device more efficient and safer to use.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include different types of clot-sensing mechanisms, such as optical or ultrasonic sensors, or varying configurations of the expandable structure and clot embedding cells. Additionally, the control unit's predictive algorithm could be trained on various datasets to improve its accuracy and adaptability.

Potential Commercial Applications and Market

The enhanced clot retrieval device has significant commercial potential in the medical device industry, particularly in the field of neurointerventional and cardiovascular treatments. The device's improved efficiency and safety features could lead to increased adoption and market share, with potential applications in hospitals, clinics, and research institutions.
