Clinically proven confidence

Tri-Staple™ technology reloads are designed to work in harmony with the natural properties of tissue before, during, and after stapling. Each reload has a stepped cartridge face that delivers graduated compression and three rows of varied height staples

The result of that design is a reload that provides superior strength and leak resistance4,8,Ω,†† across procedures.

Unique design. Universal benefits. No matter your specialty.

No single stapler can address the wide range of tissue management issues faced by surgeons on a daily basis. That’s why we’ve given our entire portfolio the power of Tri-Staple™ technology. So you can have reliable results — no matter your specialty.

Less stress1,2,†,‡

Each Tri-Staple™ reload has a stepped cartridge face that delivers graduated compression and three rows of varied height staples. That design helps generate less stress on tissue during compression and clamping.1,2,†,‡

Greater perfusion3,†

Tri-Staple™ technology’s graduated compression profile and varied height staples allow greater perfusion into the staple line.3,†


Superior performance2,4-7,§,Ω

With unique design features, reloads with Tri-Staple™ technology deliver superior performance across a broad range of thicknesses.2,4,7,§,Ω
