A newly granted patent (Publication Number: US11925369B2) describes a system designed for removing vascular thrombus from a patient's blood vessel. The system includes an outer catheter with a self-expanding filter body attached to its distal end, allowing for the capture and removal of clot material while still permitting blood flow. An inner catheter with a thrombus engagement member is used to disrupt and remove the thrombus from the vessel. The filter body is specifically designed to capture the disrupted thrombus material, ensuring effective removal from the blood vessel.

Additionally, the system may include an outer sheath and an aspiration source to create fluid flow through the filter body for enhanced thrombus removal. The method involves advancing the inner catheter to the thrombus, deploying the filter body to capture the thrombus material, and using the thrombus engagement member to disrupt the thrombus. The system's design allows for precise and efficient removal of thrombus from the blood vessel, with the flexibility to adapt to different vessel diameters and configurations, ultimately improving patient outcomes in thrombus removal procedures.
