  • Method and system for manufacturing a barbed suture
    Patent number: 12611210
    Abstract: A method for manufacturing a monofilament barbed suture. The method includes positioning a mandrel device adjacent to a rotary mount on which a razor is mounted, the mandrel device comprising a mandrel mounted to a fixture, a filament in contact with a curved surface of the mandrel; and rotating the razor with the rotary mount so that an edge of the razor impinges upon an exterior surface of the filament to impart a linear cut to the filament to a cut depth within the filament to form a barb. The mandrel has a diameter of 4 millimeters or less.
