Abstract
An embolic protection device comprising an expandable structure and a catheter. The catheter has a distal region and a working channel dimensioned to slideably receive an interventional device. The expandable structure is attached to the distal region of the catheter. The expandable structure has an expandable working channel extension and a working channel opening, the expandable working channel extension has a proximal end and a distal end, the proximal end of the working channel extension is attached to a distal end of the working channel, and the distal end of the working channel extension forms the working channel opening. The working channel opening is disposed proximate an exterior surface of the expandable structure when the expandable structure is expanded. The working channel, working channel extension, and the working channel opening form a continuous lumen.
