Overview

44% fewer leaks1,†,††  

EEA™ circular stapling now comes with our clinically proven Tri-Staple™ technology. 

That means you can have consistent performance in circular stapling — over a broad range of tissue.3,4,5,†,§ You and your patients can benefit from:

  • Greater leak protection vs. the Ethicon™* CDH1,†,‡
  • Less stress on tissue during compression and clamping6,†,‡‡,§§
  • Greater perfusion allowed into the staple line2,§,Ω

The Extra Row Matters

See how Tri-Staple™ technology stacks up to two-row circular staplers

Our EEA™ circular stapler delivers three-rows of varied height staples for consistency across a broad range of tissue thicknesses.3,4,5,†,§ Together with a sloped cartridge face3,†, it provides less stress on tissue6,†,‡‡ compared to Ethicon™* CDH and DST Series™ technology.

Tri-Staple™ technology also delivers:

  • 44% fewer leaks vs. Ethicon™* CDH1,†,††
  • Greater perfusion allowed into the staple line2,§,Ω
  • 62% reduction in firing force vs. the Ethicon™* CDH circular staplers7,†
  • The same inner/outer lumen diameters as DST Series™ technology3,†

Made For Your Procedures

Our EEA™ circular stapler with Tri-Staple™ technology was designed to support anastomosis with:

  • A sloped cartridge face,3,† that puts less stress on tissue during compression and clamping6,†,‡‡,§§
  • Louder audible feedback during firing and unclamping compared to Ethicon™* CDH7,8,†,Ω 
  • A Tilt-top™ anvil to facilitate removal

We developed features like those because procedures — and tissue thicknesses — vary. To learn about how to get optimal use from our EEA™ circular staplers in variable tissue, check out our handy guide to choosing staple heights.
