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.([FOOTNOTE=Based on internal test report #RE00069039, EEA™ circular stapler with Tri-Staple™ technology design verification report.

  • Greater leak protection1,†,‡
  • Less stress on tissue during compression and clamping([FOOTNOTE=Based on internal test report #RE00200393 rev 2, Comparison of circular staplers: tissue compression profiles as determined by 2-D static axisymmetric finite element analysis (FEA). June 17, 2021.],[ANCHOR=],[LINK=]),†,‡‡
  • 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,†,‡‡.

Tri-Staple™ technology also delivers:

  • 44% fewer leaks1,†,††
  • Greater perfusion allowed into the staple line2,§,Ω
  • 62% reduction in firing force([FOOTNOTE=Based on internal test report #RE00183973_B, Firing force and audible feedback test report. July 2020.],[ANCHOR=],[LINK=]),†
  • 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 unclamping7,([FOOTNOTE=Based on internal test report #RE00073061, Tulip formative evaluation summary. Nov. 25, 2016.],[ANCHOR=],[LINK=]),†,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.
