Abstract
The device disclosed herein is used to the remove a thrombus from the vasculature. It includes an aspiration catheter and a thrombus retrieval device that extends through the lumen of the aspiration catheter. An expandable braided assembly extends over a distal region of the retrieval device, and an activation wire extends through the lumen of the retrieval device to attach to and control the expansion of the braided assembly. Applying tension to the activation wire causes the braided assembly to expand to a diameter of the practitioner's choosing. For example, the practitioner may apply a first level of tension to the activation wire to deploy the braided assembly to a first diameter and then later change the diameter by applying a different level of tension. The expanded braided assembly contacts the thrombus and is pulled proximally toward the aspiration catheter to assist in thrombus removal.
