A two-part surgical fastener comprises a staple and a receiver which are adapted to secure body tissue together. The staple is generally U-shaped and includes at least two prongs with barbed distal ends which penetrate the tissue and are latched by the receiver. Each prong of the staple is configured as an elongated prism of hexagonal cross-section and includes a barbed tip with an enlarged hexagonal cross-section at its free end. Each aperture of the receiver is hexagonal in configuration and includes a pair of opposed ledges for engaging the barbed tip. The tip of each prong has a pointed distal end formed by a first pair of sloped surfaces which form the sharp angle and a second pair of sloped surfaces which form a blunt angle. The staple includes longitudinal ridges or grooves on the prongs which are engaged and guided by longitudinal channels or ribs provided in a staple cartridge. The staple and receiver consist of bioabsorbable material and the receiver material is more flexible than the staple material.
