Abstract:
A filter device for capturing embolic material comprising:a guide wire having a proximal end, a distal end and a stop near said distal end:an expandable frame of frame struts having a closed, radially compact form and an open, radially expanded form, said frame in said radially expanded form forming a pair of facing frame structures;filter material attached to one of said pair of frame structures;said guide wire extending through said expandable frame and said guide wire being freely movable, both rotatably and longitudinally, with respect to said expandable frame except distally beyond said stop to enable said guide wire to be guided;an actuator sleeve running over said guide wire, said actuator sleeve enabling longitudinal compression of said expandable frame and frame struts thereby causing said frame to radially expand and deploy said filter material; and,wherein said actuator sleeve extends proximally along said guide wire and includes means for temporarily latching said sleeve and expandable frame in a compressed and filter deployed state.
