Abstract: A device for closure of an atrial septal defect (ASD) by deploying a pericardial patch includes a head including a distal jaw and a proximal jaw, and a distal disc attached to the distal jaw and a proximal disc attached to the proximal jaw. Each of the distal jaw and the proximal jaw includes at least one arm which closes when the distal disc moves forward and the proximal disc moves backward. Based on an engagement status of a distal engagement portion located on the at least one arm of the distal jaw with a proximal engagement portion located on the at least one arm of the proximal jaw, the pericardial patch deploys to close the ASD.

Abstract: 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.

Abstract: A surgical device for closure Atrial Septal Defect (ASD) with minimally invasive approach and a transcatheter device for closure ASD using pericardial patch includes a distal jaw that is distal relative to a person holding the device and a proximal jaw, a guide rod which drives the jaws to pass a pericardium patch through a patient's ASD and fix the pericardium patch onto an ASD rim.

Abstract: A method of providing a surgical device for closure of Atrial Septal Defect (ASD) with minimally invasive approach includes a head portion that includes a distal jaw being distal relative to a person holding the surgical device, a guide rod which drives the distal jaw, and a plurality of first suture-guide channels attached to the distal jaw, and a body portion which is stationary and includes a cylindrical base, a proximal jaw attached to the cylindrical base, and a plurality of second suture-guide channels attached to the proximal jaw. A lever drives the distal jaw away from the proximal jaw such that the distal jaw and the proximal jaw are spaced on different sides of an ASD hole. After a suture thread sutures a pericardium patch, the lever pulls the distal jaw backward toward the proximal jaw such that the first suture-guide channels couple with the second suture-guide channels.

Abstract: A method of providing a surgical device for closure of Atrial Septal Defect (ASD) with minimally invasive approach includes drawing a pericardial patch over a distal jaw of the surgical device, while keeping a first suture-guide channels attached to the distal jaw and a second suture-guide channels attached to a proximal jaw of the surgical device closed, inserting the surgical device through a hole incised in an intercostal space of a patient and drawing the surgical device toward the ASD, while keeping the proximal jaw of the surgical device extracorporeal, manipulating forward a guide rod of the surgical device to drive the distal jaw, opening the first suture-guide channels and the second suture-guide channels to position the first suture-guide channels and the second suture-guide channels around the ASD, and withdrawing the distal jaw such that the distal jaw latches onto the proximal jaw.
