Overview

Staple line security times three.

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

That means you can have the confidence and security1,2,3,†,‡ of three rows of varied height staples7 while your patients benefit from:

  • Less stress on tissue during compression and clamping([FOOTNOTE=Based on internal test report #PCG-30, Comparison of circular staplers: tissue compression profiles as determine by 2-D static axisymmetric finite element analysis (FEA).],[ANCHOR=],[LINK=]),†,Ω
  • The potential for greater perfusion at the staple line4,5,‡,§

We recommend always stocking both purple medium/thick and black extra-thick staplers so the surgeon can make the appropriate staple height decision in the case. If a black extra-thick stapler is not available, we suggest stocking the 4.8 mm green thick tissue EEA™ circular stapler with DST Series™ technology.

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.  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.

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.7 Together with a sloped cartridge face, it provides less stress on tissue6,†,Ω compared to flat, two-row cartridges.

Tri-Staple™ technology also delivers:

  • Potential for greater perfusion at the staple line4,5,‡,§
  • 30% more security during the critical healing period1,2,3,†,‡,††
  • 60% reduction in firing force vs. the Ethicon™* ILS circular stapler([FOOTNOTE=Based on internal test report #RE00183973, Firing force and audible feedback test report. May 2019.],[ANCHOR=],[LINK=])
  • The same inner/outer lumen as DST™ series technology7

  • †Preclinical results may not correlate with clinical performance in humans.

  • ‡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.

  • ††Refers to the healing period (generally through day 28) that was evaluated in multiple preclinical (canine) survival studies designed to assess device safety and efficacy.
