ETHICON Circular Stapler
The Ethicon Circular Stapler with its Controlled Tissue Compression and Adjustable Height Staple technology is designed to deliver the desired compression necessary for a strong anastomosis and effective perfusion.1,2*
Features & Benefits
Reduced Force to Break Through the Cutting Washer4‡
The Ethicon Circular Stapler, with up to 35% reduced cutting force to break through the washer compared to the previous circular stapler, enabled users to more easily complete the firing sequence.4‡
Less Tension on Tissue During Closure and Opening5§
The Ethicon Circular Stapler, with its fixed anvil design and continuously smooth anvil shaft, produced significantly less tissue displacement during closure and tissue strain during opening than the Medtronic DST Series™ EEA™ Stapler with its tilting anvil.5§
More Device Feedback When Firing6¶
With its breakaway washer, the Ethicon Circular Stapler created more audible and tactile feedback than the Medtronic DST Series EEA.6¶

* In a porcine model maximum intraluminal pressure of an anastomosis correlated most strongly with the compression of the tissue involved in the anastomosis.
† In-vitro collagen tissue model with Ethicon Circular Staplers, 19 out of 232 collagen tissues exhibited unacceptable tissue damage with adjustable compression (CDH29A), vs. 29 out of 88 with Medtronic fixed compression (EEA28 with green cartridge). Unacceptable injury was defined as cases where the damage exceeded half of the collagen thickness.

§ Benchtop testing on porcine colon, comparing means of 1.214mm for Ethicon CDH29B (n=23) to 10.240mm for Medtronic EEA28 (n=23), p<0.001 for tissue displacement, resulting in 8.4 times less longitudinal displacement during closure for CDH29B, and comparing means of 0.022 for Ethicon CDH29B (n=23) to 0.081 for Medtronic EEA28 (n=23), p=0.0016 for tissue strain, resulting in 3.7 times less circumferential strain during opening for CDH29B.
