Next-Generation Aspiration Systems for Body Lumen
Legal Citation
Summary of the Inventive Concept
A revolutionary aspiration system that leverages AI, robotics, and real-time imaging to optimize clot removal from body lumens, providing improved patient outcomes and reduced procedure times.
Background and Problem Solved
The original patent's aspiration systems relied on manual operation and lacked real-time feedback, resulting in variable success rates and prolonged procedure times. The new inventive concept addresses these limitations by integrating advanced technologies to create a more efficient, effective, and patient-centric aspiration system.
Detailed Description of the Inventive Concept
The next-generation aspiration system comprises a neural network that predicts optimal aspiration pressure based on real-time imaging data, a vacuum control module that adjusts aspiration pressure accordingly, and a micro-robotic aspirator with synchronized micro-aspirating channels. The system can also utilize ultrasonic waves to disrupt clots, and inject clot-dissolving agents to facilitate aspiration. Real-time imaging sensors and 3D modeling enable precise navigation and targeting of the region of interest.
Novelty and Inventive Step
The integration of AI, robotics, and real-time imaging to optimize aspiration pressure and navigation, as well as the use of micro-robotic aspirators and ultrasonic clot disruption, represent a significant departure from the original patent's manual operation and lack of real-time feedback.
Alternative Embodiments and Variations
Alternative embodiments could include the use of different AI algorithms, robotic architectures, or imaging modalities. Variations could also involve adapting the system for use in different body lumens or incorporating additional features, such as automated clot detection or real-time feedback to the operator.
Potential Commercial Applications and Market
The next-generation aspiration system has the potential to revolutionize the treatment of vascular diseases, such as acute ischemic stroke, and could be marketed to hospitals, clinics, and medical device companies. The system's improved efficacy and reduced procedure times could lead to increased adoption and revenue growth in the medical device industry.
