1. A method of suturing an opening in a target tissue, the method comprising:
positioning a first pad over a target tissue at a first position on a first path for forming a first purse-string suture around the opening in the target tissue, the first pad being coupled to a first suture, wherein a first corresponding portion of the first suture is over an upper surface of the first pad, and wherein the upper surface of the first pad is configured to be oriented away from the target tissue;
coupling a first distal portion of the first suture and a second distal portion of the first suture to a second pad;
positioning the second pad at a second position on the first path;
providing a second suture coupled to one of the first pad and the second pad, the second suture for forming a second purse-string suture in the target tissue along a second path around and concentric with the first path, wherein a first corresponding portion of the second suture is over an upper surface of the one of the first pad and the second pad, and wherein the upper surface of the one of the first pad and the second pad is configured to be oriented away from the target tissue;
coupling a first distal portion of the second suture and a second distal portion of the second suture to the other of the first pad and the second pad; and
tensioning the first distal portion and second distal portion of the first suture to form the first purse-string suture, and tensioning the first distal portion of the second suture and second distal portion of the second suture to form the second purse-string suture.
