Surgical apparatus including surgical buttress

A surgical buttress includes a body portion and a band disposed on each of the distal and proximal ends thereof. The surgical buttress is configured to attach to an end effector of a surgical stapling apparatus. The body portion, having perforations disposed thereon, overlies the working surface of one of the first or second jaws of the end effector. A resilient portion extends transversely beyond the side edges of the first or second jaws. Each band remains attached to the end effector following the firing thereof. The proximal band is removably attachable to a hook feature disposed on one of the first or second jaws of the end effector. The surgical buttress can be made from suitable degradable or non-degradable materials. One embodiment contemplates a detachable and disposable single use loading unit. A method of attaching the surgical buttress to a surgical apparatus is also envisioned.
