Abstract
A protective device against embolization is provided for use in angioplasty of the carotid artery comprising a guide catheter that forms a lumen, and a tubular member axially movable in the lumen and having a distal end expandable against the walls of the artery. The distal end includes a drainage port with non-folding edges that communicates through the tubular member with an outlet port having an hemostatic valve and an access port that enables the introduction of a guide wire and angioplasty balloon. When deployed in the carotid artery, the distal end occludes antegrade flow through the vessel and induces retrograde flow that carries emboli through the drainage port and out of the body.
