Abstract
An embolic protection system and method of treating occluded vessels which reduces the risk of distal embolization during vascular interventions is provided. The embolic protection system includes a guide catheter, a multi-lumen tube having a sealing surface on the distal end and an interventional device. A method of treating a blood vessel includes providing a guide catheter and a multi-lumen elongate member having proximal and distal ends, evacuation and inflation lumens extending therebetween and a sealing surface on the distal end. The elongate member is advanced through the guide catheter into a blood vessel that supplies blood to the heart proximal a lesion. The sealing surface is expanded to engage the endoluminal surface of the blood vessel and stop antegrade flow. An interventional device is advanced through the evacuation lumen to treat the lesion.
