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.
