- (a) a backspan; and
(b) at least two prongs spaced apart from the ends of said backspan extending substantially perpendicularly from said backspan in substantially parallel relationship to each other, each prong having a shaft portion with a tip portion tapering into a distal point and at least one, substantially triangular shaped barbed means for penetrating body tissue and retaining the fastener in the body tissue, said barbed means being located on the tapered tip portion of said shaft and having a distal edge spaced apart from said distal point, said barbed means further being disposed in the body tissue without passing completely therethrough for retaining the fastener in the body tissue without engaging a retainer.

Abstract
A surgical fastener for fastening layers of body tissue as in skin grafting procedures. The fastener comprises a backspan and at least two barbed prongs. The barbs are flat, triangular and are coplanar with respect to each other, as well as being in parallel alignment with the axis of the backspan. The surgical fastener is made of bioabsorbable material to eliminate the need for removal.
