Suction flow control valve
The suction system with a vacuum-actuated valve addresses the challenge of controlling blood loss during catheter-based aspiration by automatically regulating suction based on vacuum levels, ensuring controlled aspiration and minimizing blood loss.

AI Technical Summary
Existing catheter-based aspiration devices face challenges in controlling blood loss during intravascular procedures, particularly when disengaging from blood clots, due to the risk of rapid blood aspiration with large-diameter catheters and high vacuum levels.
A suction system with a normally closed flow control valve that automatically opens in response to a predetermined vacuum threshold, allowing controlled suction and automatically closing when the vacuum level drops below the threshold to prevent excessive blood aspiration.
The system effectively reduces blood loss by automatically controlling suction during intravascular procedures, ensuring that aspiration is only initiated when contact with the blood clot is maintained and ceasing when blood is aspirated to prevent excessive bleeding.
