Abstract
An end effector includes an anvil and a cartridge assembly having a plurality of surgical staples disposed in a cavity defined therein. The cartridge assembly may include a movable driver or sled configured to deploy the surgical staple from the cavity into tissue. The surgical staple may include a linear leg and an arcuate leg extending therefrom. The linear leg may include a protruding portion to provide pressure to tissue captured by the surgical staple. A three-dimensional and/or self-supporting surgical staple may interlock its two legs upon deployment thereof.

An end effector for a surgical stapler, comprising:
- an anvil having a staple forming surface;
- and
- a cartridge assembly configured to support a surgical staple therein and being movably coupled to the anvil between unapproximated and approximated positions, the cartridge assembly including a driver configured to rotate the staple into engagement with the staple forming surface of the anvil to deform the staple.
An end effector for a surgical stapler, comprising:
- an anvil defining a staple forming surface;
- and
- a cartridge assembly movably coupled to the anvil between unapproximated and approximated positions, the cartridge assembly defining a longitudinal axis and a pocket extending at an angle relative to the longitudinal axis, the pocket being configured to support a staple therein, the cartridge assembly including a driver configured to move the staple into engagement with the staple forming surface of the anvil to deform the staple.
