    • A surgical fastener comprising a fastener member and a retainer member is disclosed. The fastener member comprises a base and a pair of substantially parallel prongs extending substantially perpendicularly from the base in substantially the same direction, each prong being spaced inward from its respective end of the base, and having a prong tip configuration that allows for improved tissue penetration and thereby minimizes splaying of the prongs. Preferably, the base is the same length as the retainer member. Preferably, the prongs are substantially equidistant from the transverse centerline of the base. Also in accordance with this invention is a surgical fastener having a prong tip which maintains its improved ability to penetrate tissue after annealing of the surgical fastener.
