Reinforcing lumen rings are configured and adapted for use in conjunction with a circular endoscopic stapling instrument having a staple cartridge assembly and an anvil assembly. The reinforcing lumen rings maintain anastomotic lumen, e.g. as formed by the circular endoscopic stapling apparatus, in an open condition. The reinforcing lumen rings can include an annular ring having an outer terminal edge and an inner terminal edge, the outer terminal edge having a diameter which is substantially equal to an outer diameter of the staple cartridge assembly and the inner terminal edge having a diameter which is substantially equal to an inner diameter of the staple cartridge assembly.

L'invention porte sur des anneaux de renfort de lumières configurés et adaptés pour être utilisés en association avec des instruments endoscopiques d'agrafage circulaire comportant un ensemble d'agrafes et une enclume. Lesdits anneaux maintiennent la lumière anastomotique en position ouverte, par exemple telle qu'elle a été formée par l'appareil endoscopique d'agrafage circulaire. Lesdits anneaux peuvent inclure un anneau annulaire présentant un bord terminal extérieur et un bord terminal intérieur le diamètre du bord extérieur étant sensiblement égal à celui du diamètre extérieur de l'ensemble d'agrafes, et le diamètre du bord intérieur étant sensiblement égal à celui du diamètre intérieur de l'ensemble d'agrafes.
