Abstract

A surgical stapling instrument including a handle assembly, an elongated body portion, a shell assembly and an anvil assembly. The elongated body portion extends distally from the handle assembly and defines a longitudinal axis. The shell assembly is disposed adjacent a distal end of the elongated body portion and includes a non-planar, tissue-contacting surface oriented obliquely with respect to the longitudinal axis. The anvil assembly includes a non-planar, tissue-contacting surface oriented obliquely with respect to the longitudinal axis. The tissue-contacting surface of the anvil assembly is configured to align with the tissue-contacting surface of the shell assembly when the anvil assembly and shell assembly are in the approximated position.
