Abstract:
1. A transvascular catheter device comprising: an elongate sheath with a first lumen and a distal end, said distal end being configured for positioning at a heart valve, a second lumen that extends coaxially with said first lumen along a portion of said elongate sheath between a proximal end of said elongate sheath and said distal end, an expandable embolic protection filter having an unexpanded delivery shape and a non-tubular expanded shape, and a plurality of radially expandable units arranged for temporarily positioning said elongate sheath at a desired position in relation to said cardiac valve when said expandable units are in an expanded state wherein: at least a portion of said expandable embolic protection filter is arranged to extend from an orifice of said second lumen; said orifice is positioned proximally with respect to said distal end of said elongate sheath; the embolic protection filter is constructed so that, when extended from said orifice, the embolic protection filter expands from the unexpanded delivery shape to a substantially planar shape that covers ostia of side branch vessels in an aortic arch and stabilizes said distal end of said sheath; and said elongate sheath comprises releasable locking members configured to controllably lock at least a portion of said elongate sheath in a locked shape.
