Multilayer structures including a porous layer and a non-porous layer are useful as buttresses when associated with a surgical stapling apparatus.

Buttress and surgical stapling apparatus

A medical device having an elongate body having a proximal portion and a distal portion, the proximal portion of the elongate body terminating in a free end; the distal portion of the elongate body terminating in a loop. The loop further includes a first plurality of anchors disposed along a surface of the loop.

Anchoring suture

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.

Methods of using shape memory alloys for buttress attachment

Systems of releasably connecting staple line buttress material to the jaws of a surgical stapling instrument are provided. The systems include retainers configured to engage the buttress material and releasably retain the buttress material on the jaws of the surgical stapling instrument prior to stapling tissue. In certain embodiments, the retainers remain with the jaws of the instrument after stapling of tissue. In alternative embodiments, the retainers remain with the buttress material after being stapled to tissue.
