Abstract
A staple pocket arrangement on the anvil portion of a surgical stapler device includes pairs of staple pockets corresponding to each one of a plurality of staples to be closed. The staple pockets may have a generally triangular shape when viewed from above. Each respective staple leg is received at a longitudinal end of the staple pocket that provides a relatively wide target area for receiving the staple leg to eliminate or at least minimize the likelihood that a staple leg will miss the staple pocket due to, e.g., misalignment between a first jaw of the surgical stapler having the anvil and a second jaw of the surgical stapler having a cartridge configured to fire the staples. The staple pockets may be arranged in rows, each row of staple pockets being longitudinally offset from another row, such that each staple pocket in a first row of staple pockets is nested with a staple pocket from an adjacent row of staple pockets to make more efficient use of space on the anvil.

45. A surgical stapler device for closing staples, each staple having a distal staple leg and a proximal staple leg, the device comprising:
-
an anvil portion including at least two rows of staple pockets, each one of the at least two rows including a staple pocket set corresponding to each staple, each staple pocket set including a distal staple pocket for receiving and forming the distal staple leg of the corresponding staple and a proximal staple pocket for receiving and forming the proximal staple leg of the corresponding staple, wherein at least a portion of a staple pocket of a staple pocket set from a first row of staple pocket sets is disposed in a region between the staple pockets of a staple pocket set from a second row of staple pocket sets, wherein a first space is defined between each staple pocket set and a second space is defined between the distal staple pocket and the proximal staple pocket of each staple pocket set, and wherein at least one proximal staple pocket of a first row of staple pocket sets is transversely aligned with at least one distal staple pocket of a second row of staple pocket sets. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52, 53, 54, 55)

56. An anvil, comprising:
-
at least two rows of staple pockets, each one of the at least two rows including a staple pocket set, each staple pocket set corresponding to a single staple and including a distal staple pocket and a proximal staple pocket, wherein a staple pocket in a first row of staple pocket sets is nested with a staple pocket from a second row of staple pocket sets, wherein a first space is defined between each staple pocket set and a second space is defined between the distal staple pocket and the proximal staple pocket of each staple pocket set, and wherein each proximal staple pocket of a staple pocket set of a first row of staple pockets is axially transversely off-set with respect to a respective proximal staple pocket of a staple pocket set of a second row of staple pockets. - View Dependent Claims (57, 58, 59, 60)

61. A surgical stapler device for forming staples, the surgical stapler supporting a plurality of unformed staples such that each staple has a distally disposed staple leg and a proximally disposed staple leg, the surgical stapler device comprising:
an anvil portion defining at least a first row and a second row of longitudinal extending staple forming pocket sets, wherein each row of staple pocket sets defines a respective transverse width dimension, and wherein the first row of staple pocket sets is nested in the second row of staple pocket sets such that a transverse width dimension of the combined first and second rows of staple pocket sets is less than or equal to a sum of the transverse width dimension of the first row of staple pocket sets and the second row of staple pocket sets. - View Dependent Claims (62, 63, 64, 65, 66)
