Abstract
An embolic protection device comprising an expandable structure and a catheter. The catheter has a distal region and a working channel. The working channel has a working channel opening disposed in the distal region of the catheter, the working channel and the working channel opening are dimensioned to slideably receive an interventional device. The working channel has a distal region and at least a portion of the distal region of the working channel is 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. The working channel opening is able to be disposed to allow an interventional device to enter the second blood vessel.
