Provided herein are surgical sutures applied to tissues, and methods of forming such sutures. Some sutures include bi-directional retainers, each of which can be deployed in two directions, but which, once deployed in one direction, resist movement in the opposite direction. Other sutures include conical shaped unidirectional retainers and include tissue engaging protrusions extending from the edges and / or angled walls of the conical retainer. |
