Abstract
An anvil member for use in a surgical stapler is annealed by localized heating, preferably induction heating. A shaped shielding means is used to cradle the anvil so as to expose the staple crimping portion of the anvil. The heating is performed so as to anneal only the delimited staple crimping portion of the anvil. All other portions of the anvil are either shielded by the cradle or are out of the heating range.
