1. A method for anchoring a suture length to a material internal to a human or another animal, the method comprising the steps of:
- positioning into an opening in a portion of the material a preformed knot configuration which is located on a first portion of a suture length, the preformed knot configuration elongate along a first length and having a first cross-sectional area, the first length extending substantially along a longitudinal direction; and
reconfiguring the preformed knot configuration into an anchoring knot by collapsing the preformed knot substantially along the longitudinal direction so as to reduce the first length and increase the cross-sectional area, thereby engaging the anchoring knot against the material.

Abstract
Methods and devices are provided for anchoring suture to tissue, incorporating anchoring devices constructed substantially from suture. The anchoring devices are constructed as longitudinally extended, preformed knot configurations that upon deployment are reconfigured to form anchoring knots having an increased cross-section relative to the preformed knot configuration, for secure lodging in tissue. The anchoring devices are suitable for single and multi-anchor surgical procedures in soft tissue or bone, and multiple anchors can be delivered using a single delivery device.
