In certain exemplary embodiments, a generally U-shaped surgical staple is provided having a base and a pair of legs extending substantially perpendicularly from opposite ends of the base respectively. The legs in use of the staple are bent through approximately 90° relative to the base. To effect a greater compression of the stapled tissue, the legs can include a penetrative portion adjacent the tip and a compressive structure which, due to its increased height relative to that of the penetrative portion, spreads the compressive forces of the staple further along the length of the incision being closed. The compressive portion also provides a depth stop to avoid the tip penetrating too deeply into the tissue in which it is deployed.
What we claim is: 1. A method for closing an incision, comprising:advancing opposed legs of an undeformed surgical staple toward an incision to position a base of the staple extending between the opposed legs across the incision and to cause penetrative tips of the legs to penetrate through tissue o
What we claim is: 1. A method for closing an incision, comprising:advancing opposed legs of an undeformed surgical staple toward an incision to position a base of the staple extending between the opposed legs across the incision and to cause penetrative tips of the legs to penetrate through tissue on opposed sides of the incision; anddeforming the surgical staple to move at least a portion of each leg within a plane to cause the penetrative tips of the opposed legs to advance toward one another along a substantially arcuate path and to pass one another to close completely, each of the legs having a leg dimension in a first direction perpendicular to and extending from the plane, at least a portion of the base being in the plane and the base having a base dimension in the first direction, each leg further including a compressive portion formed thereon that acts as a depth stop to limit a penetration depth of each leg through the tissue, the compressive portion having a compressive dimension in the first direction, the compressive dimension being greater than the leg dimension, wherein at least one of the penetrative tips substantially abuts at least one of the compressive portions when the penetrative tips are closed completely.
