Embolic protection systems
First Claim
1. An embolic protection device, which comprises:
- a catheter including a proximal region and a distal region and a working channel dimensioned to slidably receive an interventional device; and
an expandable structure mounted to the distal region of the catheter, the expandable structure including an expandable working channel extension and a working channel opening, the expandable working channel extension including a proximal end and a distal end, the proximal end of the expandable working channel extension being attached to a distal end of the working channel, the distal end of the expandable 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, the expandable working channel extension, and the working channel opening forming a continuous lumen,wherein the expandable structure defines a flow channel extending through the expandable structure from a proximal end of the expandable structure to a distal end of the expandable structure, wherein the flow channel extends along a flow longitudinal axis that extends from the proximal end of the expandable structure to the distal end of the expandable structure, the expandable structure defining a proximal opening to the flow channel at the proximal end of the expandable structure and a distal opening to the flow channel at the distal end of the expandable structure, and wherein the expandable working channel extension extends across the flow channel along a direction transverse to the flow longitudinal axis from the proximal end of the expandable working channel extension to the distal end of the expandable working channel extension.

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.
