Abstract
An improved method is provided to secure a suture relative to body tissue. A suture retainer is moved along first and second sections of a suture toward the body tissue. When a predetermined minimum force is being transmitted between the suture retainer and the body tissue, the first and second sections of the suture are gripped with the suture retainer by plastically deforming material of the suture retainer. The material of the suture retainer cold flows under the influence of force applied against the surface areas on the suture retainer. One or more bends are formed in each of the sections of the suture to increase the holding action between the suture retainer and the sections of the suture. The bends may be formed by wrapping a turn of the suture around a portion of the suture retainer. During movement of the suture retainer toward the body tissue, the bends are moved along the first and second sections of the suture.
