Embolic protection systems
First Claim
1. An embolic protection device comprising an expandable structure and a catheter, the catheter having a distal region and having a working channel dimensioned to slideably receive an interventional device, the expandable structure being attached to the distal region of the catheter, the expandable structure having an expandable working channel extension and a working channel opening, the expandable working channel extension having a proximal end and a distal end, the proximal end of the working channel extension being attached to a distal end of the working channel, the distal end of the working channel extension forming the working channel opening, the working channel opening being disposed proximate an exterior surface of the expandable structure when the expandable structure is expanded, and the working channel, working channel extension, and the working channel opening forming a continuous lumen.

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.

32. The method of claim 32, wherein the expandable structure has a generally tubular shape.
- 45. 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.
