Expansile device for use in blood vessels and tracts in the body and method

摘要

A device for expansion within a blood vessel having a wall defining a lumen in the body. A first elongate tubular member has proximal and distal extremities and has 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. A deployment mechanism is carried by the proximal extremity of the first elongate tubular member and is adapted to be operated by the human hand for controlling movement of the expansile member between the contracted and expanded positions. A biological sealant introducer is connected to the first elongate tubular member for introducing a biological sealant into the body proximal to the expansile member and external to the lumen of the vessel. The biological sealant introducing means includes a second elongate tubular member with proximal and distal extremities. A longitudinal axis and a first lumen extend from the proximal to the distal extremity of the second elongate tubular member. The distal extremity of the second elongate tubular member terminates proximal to the distal extremity of the first elongate tubular member and adjacent to said expansile member. The first elongate tubular member is carried by the second elongate tubular member.
