Overview

80% fewer leaks vs. Echelon™* Circular Powered stapler 1,†,‡

EEA™ circular stapling now comes with 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 versus the Ethicon Echelon Circular™* Powered stapler1,†,‡
  • Less stress on tissue during compression and clamping6,‡‡,§§,ΩΩ
  • 140% greater Prefusion vs Ethicon Circular™* Powered Stapler2,†,Ω

Fewer leaks.1,†,‡ No batteries required.

Take a look at how the EEA™ circular stapler with Tri-Staple™ technology compares with Ethicon's Echelon Circular™* Powered stapler.

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 face, Tri-Staple™ technology also delivers:

  • 80% fewer leaks versus Ethicon Echelon Circular™* Powered stapler1,†,Ω
  • 140% greater perfusion allowed into the staple line2,†,§
  • 60% reduction in firing force versus Ethicon™* manual 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, that puts less stress on tissue during compression and clamping6,‡‡,§§,ΩΩ
  • Louder audible feedback during unclamping compared to Ethicon™* manual CDH7,‡‡,‡‡‡
  • A Tilt-top™ anvil to facilitate removal

We developed features like those because procedures—and tissue thicknesses—vary.
