AORTIC CROSSING CATHETER

Abstract: an aortic crossing catheter for directing a crossing wire through the aortic valve may include an outer sheath, an inner sheath slidably disposed within the outer sheath, and an expandable member at least partially fixed to the inner sheath and configured to move between a constrained delivery configuration to a radially expanded deployed configuration. axial movement of the inner and outer sheaths relative one another radially expands the expandable member such that when a crossing wire is inserted through a lumen of the inner sheath, the wire is directed through the aortic valve.
