Methods of using shape memory alloys for buttress attachment
First Claim
1. A surgical stapling device, comprising:
- a tissue contacting surface of an anvil or a cartridge assembly;
a buttress material on the tissue contacting surface; and
a series of buttress attachment features movable from a first position to a second position, the buttress material being separable from the tissue contacting surface when the series of buttress attachment features is in the second position, the series of buttress attachment features being movable from the first position to the second position in response to a temperature change.

Abstract
A surgical stapling device includes a tissue contacting surface and a buttress attachment feature. The buttress attachment feature permits selectively securing a surgical buttress to the tissue contacting surface, which may be disposed on a cartridge assembly or an anvil plate of the surgical stapling device. The buttress attachment feature may include a shape memory alloy, such as a nickel titanium alloy, that is responsive to a temperature change to allow the buttress attachment feature to move between a first position where a free end of the buttress attachment feature is substantially spaced from the tissue contacting surface, and second position where the surgical attachment feature is approximated with respect to the tissue contacting surface.
