Animal Health / Covidien Products / Veterinary Surgical Stapling / EEA™ Circular Stapler with Tri-Staple™ Technology

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

Made For Today’s Procedures

Introduce next-gen circular stapling to your OR

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,†,Ω
  • Improved audible feedback7,†,‡‡
  • A Tilt-top™ anvil to facilitate removal
  • 30% more staples than staplers with the same lumen diameters8,§

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

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 staplers9,†
  • The same inner/outer lumen diameters as DST Series™ technology3,†

  • ‡Based on the addition of a third row of staples in the EEA™ circular stapler with Tri-Staple™ technology, as compared to predicate two row device designs.
  • §Compared to two-row staplers.
  • ΩFinite element analysis (FEA) was used to determine the strain profiles of three circular staplers during clamp-up. The EEA™ circular stapler with Tri-Staple™ technology demonstrated a graduated compression profile upon clamping.
