    Abstract: A device for guiding a barbed suture into a braider preferably includes an elongated body having a proximal end, a distal end, and a longitudinal axis that extends from the proximal end to the distal end of the elongated body. The elongated body includes a first channel extending along the longitudinal axis of the elongated body and having a first distal opening at the distal end of the elongated body, whereby the said first channel has a first cross-sectional area, and a second channel extending along the longitudinal axis of the elongated body and having a second distal opening at the distal end of the elongated body, whereby the second channel has a second cross-sectional area that is different than the first cross-sectional area of the first channel. The device has an elongated slot extending along the longitudinal axis of the elongated body that interconnects the first and second channels. A barbed suture is loaded into the elongated body. The barbed suture includes an elongated core having a proximal end, a distal end, a barbed section including barbs extending outwardly from the elongated core, an end effector secured to the proximal end of the elongated core, and an interconnecting segment of the elongated core that is distal to the end effector and proximal to the barbed section. The barbed section of the barbed suture is disposed within the first channel, the end effector of the barbed suture is disposed within the second channel, and the interconnecting segment of said barbed suture extends through the elongated slot.

    Abstract: A system for making braided barbed sutures includes a filament winding assembly, a barbed insert including an elongated core and barbs extending outwardly from the elongated core, and a barbed insert dispenser opening defining a passageway for orienting the barbed insert as the barbed insert is dispensed into the filament winding assembly. The barbed insert dispenser opening allows longitudinal movement of the barbed insert relative to the barbed insert dispenser opening while simultaneously preventing twisting movement of the barbed insert relative to the barbed insert dispenser opening.

    Abstract: A braided barbed suture includes a barbed monofilament insert including an elongated core having a thickness and a plurality of barbs projecting outwardly from opposite sides of the elongated core. The braided barbed suture includes a braided sheath surrounding the elongated core to form a composite core of the braided barbed suture. The composite core has a thickness and the elongated core is located in a center of the composite core. The elongated core thickness is about 6-8 mil and the composite core thickness is about 13-18 mil. A ratio of the elongated core thickness relative to the composite core thickness is between about 0.16 to 0.91. The elongated core has transition zones that form a concave profile. The braided barbed suture has a single breaking point for both the braided sheath and the barbed monofilament insert. The barbed monofilament insert has a PDS monofilament core, and the braided sheath is a VICRYL multifilament yarn braided sheath.

    Abstract: A wound closure device includes a flexible filament having a first end, a second end, and a longitudinal axis extending between the first and second ends. A plurality of barbs project outwardly from the flexible filament. Each barb has a base connected with the flexible filament, a blunt tip spaced from the base, a leading edge extending between the base and the blunt tip and facing toward the first end of the flexible filament, and a trailing edge extending between the base and the tip and facing toward the second end of the flexible filament. The trailing edge of the barb and the longitudinal axis of the flexible filament define an angle of at least 68° that opens toward the second end of the flexible filament.
