ECHELON CONTOUR™ Curved Cutter
Stapling deep within the pelvis creates challenges with achieving good staple formation, increasing the risk of leaks. The ECHELON CONTOUR™ Curved Cutter is engineered to address the difficulties of access and varying tissue conditions. It's designed to reduce leak risks1-3A through gentle tissue handling and a strong staple line, without compromising healing.3-5B

Less tissue trauma
Gripping Surface Technology (GST)—a proprietary ridged surface on the staple reload—precisely compresses tissue only where needed for 31% reduced compressive forces on tissue and 37% less tissue trauma compared to traditional flat deck staplers.3-5B

Reduced potential leak pathways
With a gentler curved design, 3D Stapling Technology minimized high stress points throughout the staple line and evenly distributed compression throughout the staple line to reduce potential leak pathways.1C

Deep pelvic access
Designed for increased visibility and optimal use in the narrower male pelvis, the unique curved head design of the ECHELON CONTOUR™ Curved Cutter gives low pelvic access and enhanced visibility of anatomic structures.8

ECHELON CIRCULAR™ Powered Stapler
Leaks during surgery can lead to serious complications, especially in challenging cases. The ECHELON CIRCULAR™ Powered Stapler significantly reduced leaks at the staple line and produced greater perfusion compared to the Medtronic EEA™ Circular Stapler with Tri-Staple™ Technology.1,2A The device combines two breakthrough innovations—3D Stapling and Gripping Surface Technologies—on one consistent and reliable powered platform.

ECHELON LINEAR™ Cutter
Leaks can have a devastating impact for patients and hospitals. Compounding this challenge, increasing patient complexity in some open procedures further elevates the risk of leaks. The ECHELON LINEAR™ Cutter provided 47% fewer staple line leaks compared to the PROXIMATE™ Linear Cutter and GIA™ Stapler with Tri-Staple™ Technology.1A
