4. Key Differences Between CDH29P and TRIEEAXL28XT
A. Lumen diameter
The CDH29P has a published lumen diameter of 29 mm, while the TRIEEAXL28XT has a 28 mm lumen size.
Although these nominal sizes are close, the devices should not be treated as identical. Buyers should confirm the exact manufacturer reference and device dimensions rather than relying on the difference being only 1 mm.
B. Shaft length and configuration
One of the clearest differences is the shaft length.
-
CDH29P: 24 cm shaft.
-
TRIEEAXL28XT: 35 cm XL shaft.
The TRIEEAXL28XT is specifically an extended-length configuration. The distinction matters when checking the exact device configuration required by a purchasing specification.
C. Staple technology
The two devices use different manufacturer technologies.
Ethicon CDH29P
-
Gripping Surface Technology.
-
3D Staples.
-
Powered device technology.
-
Two-row staple configuration.
Medtronic TRIEEAXL28XT
-
Tri-Staple technology.
-
Three rows of varied-height staples.
-
Black Extra Thick XL configuration.
-
Three published staple heights: 4.0 mm, 4.5 mm, and 5.0 mm.
These are different design configurations, not interchangeable specifications.
D. Staple-height specifications
Ethicon publishes a closed staple height range of 1.5–2.2 mm for its ECHELON CIRCULAR Powered Stapler portfolio.
Medtronic publishes open staple heights of 4.0 mm, 4.5 mm, and 5.0 mm for the TRIEEAXL28XT.
These figures describe different measurement references. They should not be compared directly to determine clinical suitability or device equivalence.
5. Important Product Identification Checks
Before sourcing either product, purchasing teams should verify the following information:
-
Manufacturer reference: Confirm CDH29P or TRIEEAXL28XT from the original product label.
-
Lumen size: Check the specified 29 mm or 28 mm configuration.
-
Shaft length: Distinguish the standard-length CDH29P from the extended-length TRIEEAXL28XT.
-
Staple configuration: Confirm the relevant manufacturer technology and staple-row specifications.
-
Tissue classification: Check the exact model's documented product configuration, including the Extra Thick designation where applicable.
-
Packaging quantity: Confirm whether the listing is sold as a single device or an outer box quantity.
-
Condition and expiration: Verify packaging integrity, sterility information, lot details, and expiration date.
-
Manufacturer documentation: Consult the current regional IFU and applicable product documentation.
Are CDH29P and TRIEEAXL28XT interchangeable?
They should not be assumed to be interchangeable. The devices have different lumen sizes, shaft lengths, staple technologies, and staple-row configurations.
A product comparison or size reference does not establish clinical equivalence. Always follow manufacturer instructions and institutional procurement requirements.
