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.
An embolic protection device comprising an expandable structure and a catheter, the catheter having a distal region and having a working channel, the working channel having a working channel opening disposed in the distal region of the catheter, the working channel and the working channel opening dimensioned to slideably receive an interventional device, the working channel having a distal region, at least a portion of the distal region of the working channel being disposed within the expandable structure, the expandable structure, when expanded in a first blood vessel, is able to stop blood flow through a second blood vessel and able to allow blood to flow through the first blood vessel, and the working channel opening is able to be disposed to allow an interventional device to enter the second blood vessel.
