Abstract
Surgical stapling apparatus are disclosed including an anvil having a working surface with a shaped topography, and a staple cartridge, in juxtaposition with the anvil. The staple cartridge includes a working surface with shaped topography which is complementary to the shaped topography of the working surface of the shaped anvil. When the anvil and the staple cartridge are approximated with or toward one another, at least a portion of the working surface of the anvil cooperates with at least a portion of the working surface of the staple cartridge to enhance alignment of the staple cartridge and the anvil in at least one of a transverse and longitudinal direction.
