Abstract
A method and device to elevate retainers on a suture thread to a desired angle such that the retainers can retain the desired elevation. The retainers can be elevated using an apparatus having at least one roller and at least one bending bar, wherein the bending bar contacts the retainers adjacent to the at least one roller to apply a force to the retainers. The retainers can also be elevated using a tube-shaped apparatus. A suture can be made up of an inner core and a coating that upon a stimuli increases the protrusion of the retainers away from the suture core. A coating can be inserted into the cut associated with the retainer and repulsive or expansive forces result in a pushing out of the cut and distending of the retainers away from the suture core.
