Surgical fastener deployment system

A deployment device comprising:

• a surgical fastener;
• a handle;
• an elongated shaft extending from the handle, at a distal portion of the shaft:
• a restraint that engages a back span of the surgical fastener to temporarily limit distal movement of the back span, the surgical fastener including two legs extending in a distal direction from opposing ends of the back span, wherein the legs have a first closed position with a first shape;
• and
• a spreader configured and arranged to engage the legs of the surgical fastener in the first closed position, wherein moving the spreader in a distal direction relative to the back span spreads the legs of the surgical fastener from the first closed position to a second open position as the back span is limited from moving distally by the restraint, wherein the restraint engages the back span in a first plane and the spreader engages the legs in a second plane different from the first plane.

• and
• an anvil, wherein as the surgical fastener is deployed the legs are formed against the anvil, and wherein the anvil forms the legs to a second shape with a width that is larger than a width of the first shape.
