Patent ID: 8777988

Claim:
An endoscopic method for closing an opening in a tissue, the opening having a first side and a second side, the method comprising: (a) receiving a wound-closure device including a suture having a first suture section and a second suture section, a first needle secured to the first suture section, where the first suture section comprises a first plurality of cuttings present in the first suture section, each cutting providing for a cut portion on the first suture section, each cut portion being a projection, the suture comprising a first plurality of projections distributed on the first suture section, the first plurality of projections being adapted to permit movement of the first suture section through tissue in a direction of the first needle and resist movement in an opposite direction by grasping tissue which surrounds the first suture section; (b) inserting the wound-closure device through an opening in a body into a cavity within the body; (c) manipulating the tissue within the cavity with an endoscopic instrument; (d) deploying the first suture section along a curvilinear path within at least the first side of the opening by a method comprising (d1) inserting the first needle in tissue of the first side; (d2) pushing the first needle along a curvilinear path through tissue of the first side until it projects out of the tissue of the first side; and (d3) pulling the first needle out of the tissue of the first side and drawing the first suture section through the curvilinear path but leaving a part of the first suture section within the first curvilinear path; (d4) inserting the first needle in tissue of the second side; (d5) pushing the first needle along a second curvilinear path through tissue of the second side until it projects out of the tissue of the second side; and (d6) pulling the first needle out of the tissue of the second side and drawing the first suture section through the second curvilinear path but leaving a part of the first suture section within the second curvilinear path, and repeating steps (d1), (d2), (d3), (d4), (d5), and (d6) to provide a continuous sinusoidal path and not a spiraling path of suture placement in the tissue which repeatedly crosses the opening; (e) securing the second suture section to at least the second side of the opening; (f) approximating the first side and the second side of the opening and thereby securing the first side to the second side and closing the opening.
