A recently granted patent (Publication Number: US11896246B2) discloses a system designed for capturing undesirable materials. The system includes a suction cannula with an expandable distal end comprising at least two expandable strips and an impermeable membrane. This expandable design allows for efficient capture of materials, with the impermeable membrane enhancing the suction force. A pump is integrated into the system to create suction through the cannula and a driving force into either a second cannula or a reservoir. The pump can be manually operated, providing control over the capturing process.

Furthermore, the system features an outer sheath that can move coaxially relative to the suction cannula, allowing for the expandable distal end to transition between collapsed and expanded positions. A filter is also included in the system to ensure the captured materials are effectively separated. The reservoir provided in the system is designed to collect the undesirable material, accommodating both fluid and air. The manually operated pump can be activated intermittently, offering flexibility in operation. Overall, the system is configured to be closed to the atmosphere, ensuring a controlled environment for capturing the undesirable material efficiently.
