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.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 60 / 781,059, filed Mar. 10, 2006, entitled “Embolic Protection Systems” the contents of which are hereby incorporated by reference herein.FIELD OF THE INVENTION

[0002] The present invention relates to embolic protection systems. These embolic protection systems are particularly well-suited for use in branched blood vessels. BACKGROUND OF THE INVENTION

[0003] Vessels are commonly treated to reduce or eliminate narrowings caused by arteriosclerotic disease. Interventional treatments can include use of balloon angioplasty, stenting, thrombectomy, atherectomy, and other procedures. During treatment particulate debris can be generated at the treatment site. Infarcts, strokes, and other major or minor adverse events are caused when debris embolizes into vasculature distal to the treatment site.

[0004] To prevent embolization of debris, embolic protection devices have been developed. During a procedure such devic...
