The only open stapling portfolio that delivers the confidence of Tri-Staple™ technology

Compared to the two-row Ethicon™* Echelon Circular Powered stapler, the three-row EEA™ circular stapler with Tri-Staple™ technology provides:

  • Greater leak protection1,†,§
  • 140% greater perfusion2,†,Ω
  • 20% greater security3,†,††
  • 78% lower removal forces4,‡‡,§§
