Thrombus extraction system for removing vascular clots
The patent US12023057B2 describes a thrombus extraction system designed for the effective removal of vascular thrombi from a patient's blood vessels. The system comprises a catheter with a lumen and a distal end, an aspiration pump that generates negative pressure within the catheter, and a shaft that can slide along the catheter's lumen. At the distal end of the shaft is a self-expanding filter body made of a permeable mesh, which is designed to conform to the inner wall of the blood vessel when deployed. This filter body captures thrombolytic material that is broken apart by a thrombus engagement member, which is positioned distally of the filter body and can slide longitudinally to disrupt the thrombus.
Additionally, the patent outlines methods for capturing and removing a vascular thrombus. The process involves positioning the aspiration catheter near the thrombus, deploying the filter body to conform to the vessel's diameter, and using a separator to disrupt the thrombus material. The system allows for the application of negative pressure through the catheter's lumen, facilitating the capture of thrombolytic material by the filter body. The separator can be mechanically operated to enhance the disruption of the thrombus, and the filter body is noted to be made from a self-expanding nitinol mesh, which aids in its deployment and functionality within the blood vessel.
