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.

Thrombectomy device and methods of use

Various implementations of a percutaneous transluminal angioplasty device include a catheter, a filter, and an expandable balloon. The filter is coupled adjacent a distal end of the catheter and is movable between an unexpanded and expanded configuration via a filter activation wire extending through a lumen of the catheter. An anti-stenotic therapeutic agent is disposed on an outer surface of the balloon, and the balloon is disposed on the catheter proximally of the filter. An axial movable sheath is positioned over the balloon and filter during deployment to a target site and is axially retracted away from the filter and balloon prior to treatment of a lesion. At the target site, the exposed filter is expanded via the filter activation wire. Then, the exposed balloon is inflated to dilate and deliver the therapeutic agent to the lesion.
