AI Technical Summary
When using suction to remove large clots, the trap may collapse due to the clogging of the trap opening due to the clot material, which in turn leads to incomplete clot removal and clot fragmentation.
A catheter system is designed, including an outer tube having an outer tube covering an elongated trap, when the elongated trap is deployed from the outer tube, the cavity of the outer tube forms a duct for applying suction to the distal opening of the elongated trap, preventing collapse, and advancing the material trapped in the distal opening of the trap by an automatic pulsation mechanism.
It effectively avoids the trap collapse, ensures the complete removal of the clot, and improves the system's removal capability and efficiency.
