1. A surgical stapling apparatus, comprising:
- a cartridge assembly defining a first tissue contacting surface, the cartridge assembly housing a plurality of surgical fasteners therein, the cartridge assembly defining at least one distal attachment point and at least one proximal attachment point;
an anvil assembly defining a second tissue contacting surface, the anvil assembly movably secured in relation to cartridge assembly, the anvil assembly defining at least one distal attachment point and at least one proximal attachment point, wherein the at least one proximal attachment point of the anvil assembly is offset an axial distance from the at least one proximal attachment point of the cartridge assembly; and
a surgical buttress releasably secured to each of the first tissue contacting surface and the second tissue contacting surface, the surgical buttress including a body portion configured to substantially overlie at least one of the first and second tissue contacting surfaces of either the first length and second length cartridge assembly and anvil assembly;
wherein each surgical buttress defines a distal attachment feature for registration with the distal attachment point of the cartridge assembly and the anvil assembly;
wherein each surgical buttress defines a first proximal attachment feature and a second proximal attachment feature offset an axial distance from the first proximal attachment feature;
wherein the first proximal attachment feature registers with the proximal attachment point of the cartridge assembly; and
wherein the second proximal attachment feature registers with the proximal attachment point of the anvil assembly.

27. A surgical buttress for use with a surgical stapling apparatus having a cartridge assembly of any number of lengths and an anvil assembly of any number of lengths corresponding to the lengths of the cartridge assembly, wherein each of the cartridge assembly and anvil assembly defines respective juxtaposed tissue contacting surfaces, and wherein the cartridge assembly includes a plurality of staples stored in staple slots thereof for formation against staple formation pockets of the anvil assembly, the surgical buttress comprising:
-
a body portion configured and dimensioned to at least one of; overlie all of the staple slots of the cartridge assembly for any length cartridge assembly, and overlie all of the staple formation pockets of the anvil assembly for any length anvil assembly; a neck portion extending from the body portion; and a head portion connected to the neck portion and opposite a distal end of the body portion, wherein the body portion defines at least one pair of opposing proximal recesses, each of the at least one pair of opposing proximal recesses is formed on an opposing lateral side of the body portion near a proximal edge of the body portion.
