Abstract
A closure device for percutaneously forming a closure of a puncture in the tissue of human body. The device comprises a flexible elongate tubular member having proximal and distal extremities and a longitudinal axis. The flexible elongate tubular member has a first lumen extending from the proximal extremity to the distal extremity. A closure assembly is carried by the distal extremity of the flexible elongate tubular member and is movable between contracted and expanded positions. The closure assembly includes a closure mechanism covered by an impermeable membrane. A handle is carried by the proximal extremity of the flexible elongate tubular member and is adapted to be grasped by the human hand. A deployment mechanism is carried by the handle and extends through the flexible elongate tubular member and is coupled to the closure assembly for moving the closure assembly from the contracted position to the expanded position.
