摘要：
A barbed suture is disclosed having barbs defined by a variable-angle cut surface. A cutting bed supports the suture during cutting. A cutting device is moved through the suture thread along a selected path. The angle of the cutting device is changed during cutting so that there is a corresponding change in the angle of the cut surface which defines each barb. A cutting arm is articulated to allow change of the angle of the cutting device. The change in the angle of the cutting device is used to control the shape and depth of cut of the barbs.
