A device for expansion within a blood vessel having a wall defining a lumen in the body. The device comprises a first elongate tubular member having proximal and distal extremities and having a longitudinal axis. An expansile member is carried by the distal extremity of the first elongate tubular member and is movable between contracted and expanded positions. The expansile member has a predetermined configuration in the expanded position. A deformable membrane covers the expansile member and is sized so as to be capable of overlying and underlying the expansile member in the expanded position. Deployment means are carried by the proximal extremity of the first elongate tubular member and are adapted to be operated by the human hand for controlling movement of the expansile member between the contracted and expanded positions.

[ What is claimed:] [1.] A device for expansion within a blood vessel having a wall defining a lumen in the body comprising a first elongated tubular member having proximal and distal extremities and having a longitudinal axis, an expansile member carried by the distal extremity of the first elongated tubular member and movable between contracted and expanded configurations, said expansile member in the expanded configuration having distal and proximal surfaces, a deformable membrane carried by the first elongated tubular member, said deformable membrane being formed so as to be capable of expanding to have a first layer overlying the distal surface of the expansile member in the expanded configuration and a second layer underlying the proximal surface of the expansile member in the expanded configuration and deployment means carried by the proximal extremity of the first elongated tubular member and coupled to the expansile member, said deployment means being adapted to be operated by the human hand for controlling movement of the expansile member between the contracted configuration permitting introduction into a lumen of a blood vessel and the expanded configuration within the lumen of the blood vessel, and thereafter to the contracted configuration permitting removal from the blood vessel.
