Abstract
A system for making braided barbed sutures includes a filament winding assembly, and a guide assembly including at least one barbed insert dispenser opening defining a passageway for orienting a barbed insert. The guide assembly is adapted to dispense at least one barbed insert from the dispenser opening into the filament winding assembly for winding a plurality of filaments around the at least one barbed insert for making a braided barbed suture. The passageway of the dispenser opening is adapted to allow longitudinal movement of the barbed insert relative to the passageway while simultaneously preventing twisting movement of the barbed insert relative to the passageway. As the barbed insert is being dispensed, the barbed insert dispenser opening is selectively rotatable for imparting rotation to the barbed insert as the filaments are wound about the barbed insert. The passageway may be an elongated slit having a greater width than height.
