Abstract: A stapling device for forming multiple tissue plications without needing to reload the device between plications is described. The device includes staple and anvil housings that move toward and away from a tissue-capture position. A cartridge holder in the staple housing supports a cartridge with multiple groups of offset staple slots, where the slots in each group are circularly arrayed about a cartridge center axis. A staple driver in the staple housing carries a plurality of arms for engaging and ejecting the staples in a first group of staples in the cartridge, when a tissue fold is captured between the cartridge assembly and anvil in the anvil housing. When the staple driver is retracted, after a tissue plication is formed, the cartridge assembly and tissue drive are indexed to eject the next-up group of staples.
