In a surgical system, a stapling instrument (1) comprises a flexible shaft device (4), a handle (2), and a staple fastening assembly (6). The staple fastening assembly (6) includes a curved cartridge (10), which comprises at least one curved open row of staples, and, opposite to the cartridge (10), a curved anvil (20), which has a staple forming face and is adapted to cooperate with the cartridge (10) for forming the ends of the staples exiting from the cartridge (10). Preferably, the staple fastening assembly (6) is adapted to allow unobstructed access towards concave inner faces of the cartridge (10) and of the anvil (20). The anvil (20) can be moved relatively with respect to the cartridge (109, from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue. The surgical system further includes a retractor adapted to draw tissue into the space between the cartridge (10) and the anvil (20), when the cartridge (10) and the anvil (20) are in the spaced position. In a preferred application, the surgical system is used in the treatment of gastroesophageal reflux desease (GERD).
