Abstract:
A device for expansion within a blood vessel having a wall defining a lumen in the body comprising an elongated tubular member having proximal and distal extremities and having a longitudinal axis, an expansile member carried by the distal extremity of the elongated tubular member and movable between contracted and expanded configurations, a deformable membrane having proximal and distal outer surfaces at least partially covering the expansile member in the expanded configuration, said proximal and distal outer surfaces having substantially different configurations when the expansile member is in the expanded configuration, deployment means carried by the proximal extremity of the elongated tubular member and coupled to the expansile member for moving the expansile member between the contracted and expanded configurations and a handle assembly carried by the proximal extremity of the elongated tubular member and coupled to said deployment means.
