Surgical staple
First Claim
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; and
deforming 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.

Abstract
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.

11. A method for closing an incision, comprising:
-
positioning a base of an undeformed surgical staple across an incision formed in tissue; advancing at least two legs extending from opposed ends of the base toward the tissue to cause a penetrative portion of each leg to extend through the tissue on opposed sides of the incision; and deforming the surgical staple to move at least a portion of each leg within a plane by bending each leg relative to the base to cause the penetrative portions of each leg to advance toward one another and to cause a compressive portion formed on each leg to engage and compress the tissue and thereby limit penetration of the penetrative portion of each leg into the tissue, 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 having a base dimension in the first direction, 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. 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, the opposed legs extending at an angle from each end of the base and terminating at a free end, the base and the legs lying in substantially a common plane; and deforming the surgical staple to move at least a portion of each leg within the common plane by bending each leg relative to the base to cause the penetrative tips of the opposed legs to advance toward one another along a substantially arcuate path, each of the legs having a leg dimension in a first direction perpendicular to and extending from the common plane, the base having a base dimension in the first direction, each leg further includes 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. - View Dependent Claims (22, 23)
