Abstract:
1. A method of cutting barbs on a suture having a longitudinal axis, said method comprising the steps of: providing a suture having a lateral x-axis, a forward y-axis, and a downward z-axis; providing a cutting blade; creating a barb on said suture by the motion of the blade which takes into account a cutting action by the blade on the suture in three dimensions along the x-y-z axes of the suture caused by blade geometry in conjunction with blade motion, with the blade having motion at least along the x-axis; and providing a means for moving the blade to cause said cutting action to create the barb; wherein the blade motion and blade geometry each cause the cutting in at least one of the x-, y-, and z-axes.
