Abstract:
1. A method of providing a surgical device for closure of Atrial Septal Defect (ASD) with minimally invasive approach, said method comprising: drawing a pericardial patch over a distal jaw of the surgical device, while keeping at least one first suture-guide channel attached to said distal jaw and at least one second suture-guide channel 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 to negotiate the distal jaw through the ASD; opening the at least one first suture-guide channel and the at least one second suture-guide channel to position the at least one first suture-guide channel and the at least one second suture-guide channel around the ASD; withdrawing the distal jaw such that the distal jaw latches onto the proximal jaw; pulling back the pericardial patch in conjunction with an ASD rim to secure the pericardial patch and the ASD rim between the at least one first suture-guide channel and the at least one second suture-guide channel; employing a malleable needle extracorporeally to pass a suture thread into a space between the guide rod and an internal part of a cylindrical base, which supports a body portion of the surgical device, to suture the pericardial patch onto the ASD rim through the at least one first suture-guide channel and the at least one second suture-guide channel; re-steering forward the distal jaw to release the pericardial patch and release the suture from the guide channels; shutting the at least one first suture-guide channel and the at least one second suture-guide channel into respective original positions on the distal jaw and the proximal jaw; withdrawing the distal jaw from the ASD and lodging the distal jaw upon the proximal jaw removing the surgical device from a body of the patient; and orienting a plurality of knots extracorporeally toward the ASD to secure said suture of the pericardial patch to the ASD rim.
