Abstract
A method for carotid endarterectomy. A blood filter is positioned within a carotid artery downstream of an atheromatous plaque. The filter is expanded. The carotid artery is clamped upstream and downstream of the atheromatous plaque while the filter is expanded. An endarterectomy procedure is performed on the region of the carotid artery having the atheromatous plaque. The carotid artery is unclamped while the filter is expanded. In certain cases a shunt is positioned in a region of the carotid artery having the atheromatous plaque and secured to the shunt by clamping, the shunt comprising a tubular member having a proximal opening, a distal opening, and a lumen therebetween.
