ABSTRACT:
A surgical stapler is disclosed which includes a first body portion supporting an anvil which defines a fastener forming surface and a second body portion configured to releasably mate with the first body portion and having an elongate retention channel extending from a distal end thereof. A first disposable loading unit is provided which is configured to be removably supported in the retention channel and which includes a staple housing carrying a plurality of staples arranged in at least two parallel rows which, when applied to body tissue, form staple lines having a first lengthwise dimension. A second disposable loading unit is provided which is configured to be removably supported in the retention channel and which includes a staple housing carrying a plurality of staples arranged in at least two parallel rows which, when applied to body tissue, form staple lines having a second lengthwise dimension different from that of the staple lines formed by the first loading unit. The loading units and stapler can be packaged as a kit.
