More Information
Summary:In some examples, a catheter includes an elongated body defining an inner lumen and comprising an expandable member disposed at a distal portion of the elongated body, and a rotatable cutting tool located within an inner lumen of the elongated body, the rotatable cutting tool configured to segment a thrombus into smaller pieces while an aspiration force pulls the thrombus proximally into the inner lumen. In some examples, the catheter further comprises an intermediate structure oriented radially between the rotatable cutting tool and an interior surface of the elongated body, the intermediate structure configured to prevent the cutting tool from contacting the interior surface of the elongated body. In some examples, a stopper is configured to limit movement of the cutting tool distally past a distal end of the expandable member.
