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.

[ What is claimed:] [1.] A device for percutaneously forming a closure of a puncture in the tissue of the human body comprising a flexible elongate tubular member having proximal and distal extremities and extending along a longitudinal axis, the flexible elongate tubular member having a first lumen extending from the proximal extremity to the distal extremity, a closure assembly carried by the distal extremity of the flexible elongate tubular member, the closure assembly including a closure member movable between contracted and expanded positions, a deformable membrane substantially covering the closure member and secured to the distal extremity of the flexible elongate tubular member, a handle carried by the proximal extremity of the flexible elongate tubular member and adapted to be grasped by the human hand and deployment means carried by the handle and including a push-pull element having proximal and distal extremities, said deployment means extending through the flexible elongate tubular member and being coupled to the closure member for moving the closure member between the contracted position permitting introduction into a puncture and the expanded position permitting substantial occlusion of the puncture, and thereafter to the contracted position permitting removal from the puncture.
