Bariatric surgery

Tackle variable tissue
with confidence

Bariatric surgery:
The main challenges

In bariatric surgery, particularly in procedures that involve creating a stapled gastric pouch or sleeve, staple line leaks are a known complication. If the staple fails to hold the tissue together, it can result in a potentially life-threatening leak. Patients who experience a staple line leak may require extended hospitalization, additional surgeries, and prolonged recovery times.

Surgeons can be confident in the reliability of their staple lines with support from Tri-Staple™ technology and surgical energy devices from Medtronic.

Minimize complications to
increase confidence

In bariatric surgery, a strong staple line is crucial to minimizing complications. With unique design features, reloads with Tri-Staple™ technology deliver superior performance across a broad range of thicknesses.1-5,†,‡

Products that enhance outcomes

Reinforced reloads with Tri-Staple™ technology

Preload confidence and strengthen staple lines. Reinforced reloads with Tri-Staple™ technology provide:

  • Significantly higher burst pressure compared to nonbuttressed reloads6,§
  • 15 times lower incidence of bleeding compared to nonbuttressed reloads7,Ω
  • More efficiency, saving an average of 7 to 10 minutes8,††
