1. A self-retaining suture comprising:

  • a. a needle having a first diameter;

    b. a suture comprising;

    i. a first end for penetrating tissue, wherein the first end is attached to the needle;

    ii. an elongated suture body having a periphery;

    iii. a first plurality of retainers on the periphery of the elongated body and oriented to the first end, the first plurality of retainers yielding toward the suture body during movement of the suture through tissue in a direction of deployment of the first end, and resisting movement of the suture, when in tissue, in a direction substantially opposite the direction of deployment of the first end; and

    iv. a second end having a variable loop of variable circumference, wherein the variable loop includes a fixed loop slidably engaging the elongated body for slidingly varying the circumference of the variable loop, wherein the fixed loop has no retainers on its surface and said fixed loop is formed by passing a non-deployment terminus of the suture body around and back upon itself and attaching said non-deployment terminus to the suture body such that said non-deployment terminus is located outside the interior of the fixed loop, wherein the fixed loop has a second diameter that is less than the first diameter that is configured to prevent the needle from passing through the fixed loop, and wherein the first end is configured to pass through the variable loop to secure tissue as an anchor, the anchor preventing movement of the suture in the direction of deployment of the first end.
