A recently granted patent (Publication Number: US11963694B2) outlines a method for removing thrombus from a body lumen using a specialized device. The method involves inserting a device into the body lumen, which includes a catheter member, a thrombus capture body, a macerator, a biasing element, and a thrombus blocking body. The device is designed to capture and remove thrombus from the body lumen by deploying the thrombus capture body and the thrombus blocking body in a coordinated manner. The thrombus is broken up by the macerator and removed from the body lumen via an extractor, ensuring effective thrombus removal.

Furthermore, the patent details additional features of the device, such as introducing a thrombolytic agent into the body lumen, causing vibration of the thrombus capture body, and utilizing a helical member for rotation. The device is also equipped with a cage-like structure with apertures for capturing the thrombus effectively. The method involves a series of steps to ensure the thorough removal of thrombus from the body lumen, including deploying, moving, and actuating various components of the device. By combining the functions of the macerator, extractor, and biasing elements, the device offers a comprehensive solution for thrombus removal in a minimally invasive manner.
