Abstract:
1. A method for removing emboli from a vessel, the method comprising: providing a catheter having proximal and distal ends, a first lumen extending therethrough, and a distal occlusion element disposed on the distal end of the catheter; providing a dilator having proximal and distal ends and a lumen extending therethrough, wherein the dilator is disposed within the first lumen of the catheter; providing a self-expanding occlusion element having proximal and distal ends within the lumen of the dilator; ejecting the self-expanding occlusion element from the dilator to occlude flow in the external carotid artery; removing the dilator from within the first lumen of the catheter; deploying the distal occlusion element to occlude antegrade flow through the vessel; and inducing reverse flow in the vessel to cause blood and emboli to flow into the first lumen of the catheter.
