Abstract

A multiple coil staple is provided which includes a backspan and a pair of spaced legs. The backspan includes one or more pockets configured to induce coiling of the legs of the staple. A multiple coil staple applier is also provided which includes a pusher having a distal face defining a staple engagement surface and one or more staple deforming pockets. Each staple deforming pocket is configured to induce coiling of the legs of a staple. The multiple coil staple and staple applier facilitate joining of tissues having wider ranges of thicknesses using a single size staple.
