ECHELON+ Stapler
ECHELON+ Stapler
The ECHELON+Stapler with GST Reloads advances staple line security to deliver fewer leakage pathways at the staple line, even in challenging conditions.1*
The Dynamic Firing in the ECHELON+ Stapler with GST Reloads slows as it engages thick tissue to optimize compression and audible feedback.2†
ECHELON+ Anvil is designed for consistent compression and to optimally capture and form staples.3 It features wide tapered anvil pockets for optimal capture area3, and atraumatic tapered tip designed to achieve gentle tissue handling and optimized otomy entry.3‡
Advanced staple line security, even in challenging conditions1*
Less malformed staples4§
ECHELON+ Anvil is designed for consistent compression and to optimally capture tissue and form staples.3
Fewer leakage pathways at the staple line5¶
ECHELON+ Stapler delivered fewer leakage pathways at the staple line across a range of physiologic to supraphysiologic pressures5¶ and demonstrated better staple formation in thick tissue compared to Medtronic Staplers with Tri-Staple™ Reloads. 4§
More uniform compression.6β Less tissue slippage7€
The ECHELON+ Stapler with GST Reloads demonstrated 32% more uniform staple line compression6β and delivered 4x less slippage compared to Medtronic Signia with Tri-Staple™ Reloads.8\\
Echelon Plus Stapler Body of Evidence
Since 2017, the use of ECHELON Powered Staplers has demonstrated an association with improved hemostasis-related and economic outcomes¥ – across tissue types, patient populations, and countries—in large-scale, peer-reviewed studies.9-13

* Advancing staple line security with fewer leakage pathways and less malformed staples. Fewer leakage pathways: benchtop testing in porcine tissue ≤ 30mmHg (26mmHG average pressure experienced during typical leak test), comparing Ethicon ECHELON+ Stapler PSEE60A with GST Reloads GST60B to Medtronic Signia™ and Endo GIA™ Staplers with Tri-Staple™ Reloads EGIA60AMT. Cumulative number of leaked tests (0/30), (7/30) & (9/30) respectively, n=30, p < 0.05. Fewer malformed staples: benchtop testing in 3.3mm and 4.0mm porcine tissue comparing malformed staples between ECHELON+ Stapler with GST Reloads (GST60B, GST60T) to Medtronic Signia™ Stapler with Tri-Staple™ Reloads (EGIA60AMT, EGIA60AXT) and Endo GIA™ with Tri-Staple™ Reloads (EGIA60AMT, EGIA60AXT). Percentage malformed results: 1.14% vs 4.28%, p < 0.05
† Dynamic Firing refines the performance of the ECHELON+ Stapler to reduce variation within design specifications. The average transection time difference between 1.0mm and 4.0mm porcine tissue was 4.889 vs 2.992, p-value <0.05
‡The design of the ECHELON+ Stapler is refined with an updated anvil to reduce variation within design specifications.
§ Benchtop testing in 3.3mm and 4.0mm porcine tissue comparing malformed staples between ECHELON+ Stapler with GST Reloads (GST60B, GST60T) to Medtronic Signia™ Stapler with Tri-Staple™ Reloads (EGIA60AMT, SIG60AXT) and Endo GIA™ with Tri-Staple™ Reloads (EGIA60AMT, EGIA60AXT). Percentage malformed results: 1.14% vs 4.28%, p < 0.05
¶ Benchtop testing in porcine tissue ≤ 30mmHg, ≤ 40mmHg, ≤ 50mmHg (26mmHG average pressure experienced during intra-operative leak test), comparing Ethicon ECHELON+ Stapler PSEE60A with GST Reloads GST60B to Medtronic Signia™ and Endo GIA™ Staplers with Tri-Staple™ Reloads EGIA60AMT. Leak results at ≤ 30mmHg, ≤ 40mmHg, ≤ 50mmHg respectively, (0/30, 7/30, 14/30), (7/30, 13/30, 23/30), (9/30, 21/30, 22/30), p < 0.05.
β Benchtop testing in 3.2mm synthetic tissue comparing staple line compression between ECHELON+ Stapler with GST Reloads (PSEE60A, GST60B, GST60G) to Medtronic Signia™ and Endo GIA™ Staplers with Tri-Staple™ Reloads (EGIA60AMT). Resulting in a statistically significant compression uniformity, p<0.05.
€ In benchtop testing in porcine tissue, the ECHELON™ GST System (PSEE60A, GST60G) had less mean longitudinal change in 3.3mm thick tissue, 0.94 vs. 3.65, compared to the Signia™ Stapling System (SIGPHANDLE, EGIA60AMT), p-value <0.05. Based on unchanged design input specifications between ECHELON FLEX™ GST System and ECHELON+ Stapler with GST Reloads, no significant difference in performance is expected.
\\ In benchtop testing in porcine stomach tissue, the ECHELON+ Stapler with GST Reloads (PSEE60A, GST60T) had less mean longitudinal change in 4.0mm thick tissue, 0.79mm vs. 4.09mm, compared to the Signia™ Stapling System (SIGPHANDLE, SIG60AXT), p-value <0.05.
