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

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 feedback([FOOTNOTE=Based on internal test report #RE00073061, Tulip formative evaluation summary.],[ANCHOR=],[LINK=]),†,‡‡
  • A Tilt-top™ anvil to facilitate removal
  • 30% more staples than staplers with the same lumen diameters([FOOTNOTE=Zhang J. The use of the language “EEA™ circular stapler with Tri-Staple™ technology has 30 percent more staples in the staplers of the same lumen diameters as compared to two row circular staplers” in marketing materials [memorandum]. North Haven, CT: Medtronic.],[ANCHOR=],[LINK=]),§

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 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,‡‡

  • §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.
