A bioabsorbable surgical fastener comprising a fastener member and an interlocking retainer member. The surgical fastener has a total mass of less than 4 mg/transverse mm, thereby reducing the amount of foreign matter present at the wound site and facilitating faster resorption, while effecting hemostasis. The retainer member preferably has longitudinally extending slots on the lateral sides of the retainer for allowing transverse expansion of the columnar members into which the prongs of the fastener member are locked. Fins on both the lateral and transverse sides of the prongs provide extra strength, and stability during implantation. Stopping surfaces prevent the fastener's barbed tip from exiting the opposite side of the retainer.
