Disclosed is a surgical stapling apparatus and method of use that includes a cartridge assembly which is capable of being reloaded during a surgical procedure without being removed from the surgical site. This allows a surgeon to continue a surgical operation without withdrawing or removing the surgical stapler for reloading and thus reduces the length of the surgery while allowing the physician to concentrate solely on the surgical procedure rather than dividing attention between the surgical procedure and reloading of the surgical stapler. The surgical stapling apparatus includes an elongate member having a plurality of fasteners arranged in a plurality of longitudinally extending rows which is longitudinally translatable through the cartridge to position the plurality of fasteners relative to a plurality of retention slots extending through an upper surface of the cartridge.
