AI Technical Summary
Technical Problem
The existing aspiration catheters have a fixed diameter, which makes it impossible to quickly and effectively remove large or densely packed thrombi.
Method used
Design a suction conduit including an inner tube, a tube seat, and a diameter expansion assembly. By circumferentially stretching the diameter expansion assembly away from the outer wall of the inner tube, the diameter of the suction port of the inner tube can be adjusted to increase the suction effect.
Benefits of technology
It improves the suction capability for larger or denser thrombi, thus enhancing the suction effect.
