Abstract

Subcutaneous sinusoidal wound-closure techniques use one-way sutures. The one-way sutures have tissue-grasping surface features which allow passage of the suture in one direction through tissue, but not in the opposite direction. In closing a wound, the one-way suture is deployed along a curvilinear path which passes alternately through subcutaneous tissue on opposed sides of the wound. The wound-closure techniques allow approximation of the sides of the wound without knots, avoid loop stitching and reduce scarring.

1. A method for closing a wound 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, a first needle secured to the first suture section and a first plurality of barbs projecting from the first suture section, the first plurality of barbs 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;

(b) deploying the first suture section along a continuous sinusoidal path which crosses the wound from the first side to the second side of the wound and then back from the second side to the first side of the wound; and

(c) approximating the first side and second side of the wound.

2. The method of claim 1, wherein step (b) comprises deploying the first suture section along a continuous sinusoidal path which repeatedly crosses the wound from the first side to the second side of the wound and then back from the second side to the first side of the wound.

3.

4. The method of claim 3, further comprising:

(d) after reaching said one end of the wound, inserting the first needle into an insertion point on one side of the wound, passing the needle through skin at an exit point displaced from the wound, drawing a remaining part of the first suture section through the skin at the exit point, and cutting off the remaining part of the first suture section.

5. The method of claim 1, wherein step (b) comprises deploying the first suture section along a continuous sinusoidal path which crosses the wound from the first side to the second side of the wound and then back from the second side to the first side of the wound by performing the following steps alternately on the first side of the wound and the second side of the wound:

(b1) inserting the first needle into an entrance point in tissue;

(b2) pushing the first needle along a curved path through the tissue until the first needle extends out of the tissue at an exit point displaced along the wound from the entrance point; and

(b3) gripping the first needle and drawing the first suture section through the tissue leaving a length of the first suture section in the tissue between the entrance point and the exit point.

6. The method of claim 1, wherein:

step (a) comprises 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 and a first plurality of barbs distributed on the first suture section, the first plurality of barbs being adapted to permit movement of the first suture section through tissue in the direction of the first needle and resist movement in an opposite direction; and

wherein the method further comprises;

(d) securing the second suture section to a tissue of the wound.

7. The method of claim 6, wherein:

step (a) comprises 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 and a first plurality of barbs distributed on the first suture section, the first plurality of barbs being adapted to permit movement of the first suture section through tissue in the direction of the first needle and resist movement in an opposite direction, a second needle secured to the second suture section and a second plurality of barbs projecting from the second suture section, the second plurality of barbs being adapted to permit movement of the second suture section through tissue in the direction of the second needle and resist movement in an opposite direction; and

step (d) comprises securing the second suture section to a tissue of the wound by deploying the second suture section along a continuous sinusoidal path which crosses the wound from the second side to the first side of the wound and then back from the first side to the second side of the wound.

8. The method of claim 7, wherein step (d) comprises securing the second suture section to tissue by deploying the second suture section along a continuous sinusoidal path which crosses the wound from the second side to the first side of the wound and then back from the first side to the second side of the wound by performing the following steps alternately on the second side of the wound and the first side of the wound:

(d1) inserting the second needle into an entrance point in tissue;

(d2) pushing the second needle along a curved path through the tissue until the first needle extends out of the tissue at an exit point displaced along the wound from the entrance point; and

(d3) gripping the second needle and drawing the second suture section through the tissue leaving a length of the second suture section in the tissue between the entrance point and the exit point.

9. The method of claim 7, wherein step (d) comprises securing the second suture section to tissue by deploying the second suture section along a continuous sinusoidal path which repeatedly crosses the wound from the second side to the first side of the wound and then back from the first side to the second side of the wound as necessary until reaching one end of the wound.

(b) using the needle to draw the first strand portion along a curvilinear subcutaneous path which passes alternately through tissue of the first side and tissue of the second side; and

(c) approximating at least a portion of the first side and the second side of the wound.

12. The method of claim 11, wherein step (b) comprises using the needle to draw the first strand portion along a sinusoidal subcutaneous path which passes alternately through tissue of the first side and tissue of the second side.
