Abstract
This invention discloses a multi-channel secondary thrombus aspiration catheter, relating to the field of medical device technology. It includes a primary catheter and a control handle, the control handle being fixedly disposed at the proximal end of the primary catheter. It also includes multiple secondary catheters; each secondary catheter is slidably disposed within the primary catheter, and each secondary catheter has a pre-bent tip at its distal end. This invention allows for thrombus aspiration from branch vessels by sliding multiple thinner secondary catheters within the primary catheter. It also facilitates guidewire placement in secondary catheters at different locations, eliminating the need for multiple guidewire changes during the procedure. Furthermore, the secondary catheters at different locations can be configured with different diameters, thus adapting to different vascular conditions, reducing catheter changes, and providing convenient operation.
