Covidien Endo Gia Universal Articulating Loading Unit 30-2.5mm 030451 Providing superior staple line security. The staple wire gauge used in "open staplers" is heavier and does not require an additional row of staples. The Endo GIA Universal places two, triple-staggered rows of titanium staples and simultaneously divides the tissue and preloaded reinforcement material between the two, triple-staggered rows. Every cartridge comes with a new sterile knife blade. Using a new knife for Each firing ensures that it will never dull through repeated use and reduces the risk of cross-contamination that exists when reusing the same knife blade.
