A device for percutaneous transcathetral closure of Atrial Septal Defect by deploying a pericardial patch without ardiopulmonary bypass includes a guide, and a head including a distal jaw and a proximal jaw. The guide includes guide knobs which move guide levers of the guide forward and backward via a rod and control the head. Each of the distal jaw and the proximal jaw includes a plurality of alms which closes when a distal disc moves forward and a proximal disc moves backward. The aims of the distal jaw and the arms of the proximal jaw open through a pressure when the distal disc moves backward and the proximal disc moves forward. When the arms of the distal jaw and the aims of the proximal jaw are completely open, pins located on the arm of the distal jaw engage with sockets located on the arm of the proximal jaw.
