1. An end effector, comprising:
- a first jaw comprising a fastener cartridge, wherein said fastener cartridge comprises;
a cartridge body including a deck configured to support tissue;
fastener cavities defined in said cartridge body; and
fasteners removably positioned within said fastener cavities; and
a second jaw comprising an anvil, wherein said anvil comprises;
a tissue supporting surface configured to support tissue;
forming pockets configured to deform said fasteners; and
anvil projections extending from said tissue supporting surface, wherein said anvil projections at least partially surround said forming pockets, wherein said anvil projections are configured to control the flow of tissue relative to said tissue supporting surface and said deck, wherein said anvil projections at least partially support said fasteners as said fasteners are ejected from said fastener cavities, and wherein said anvil projections extend between said fastener cavities.

Abstract
An end effector can comprise, one, a fastener cartridge including a plurality of fasteners stored therein and, two, an anvil configured to deform the fasteners. The anvil can further comprise extensions extending therefrom which can control the flow of tissue relative to the fastener cartridge and/or support the fasteners as they are ejected from the fastener cartridge. The extensions can having different sizes and/or configurations.
