Abstract:
1. A filter device for capturing embolic material in a blood vessel comprising: a guide wire having a proximal end and a distal end; an expandable frame of frame members having a radiopaque coating and having a closed, radially compact form and an open, radially expanded form and a fore end and an aft end, said aft end coupled to said distal end of said guide wire, said frame of frame members in said radially expanded form forming a pair of facing generally frustoconical frame structures; a filter material attached to one of said pair of frustoconical frame structures; an actuator sleeve with a proximal end and a distal end adapted to run over said guide wire, said actuator sleeve enabling longitudinal compression of said expandable frame and frame members thereby causing said frame to radially expand and deploy said filter material; and one of a sleeve and guide wire lock at said proximal end of said actuator sleeve or a frame and guide wire lock at said fore end.
