Intelligent Compression - Optimized

Covidien's Tri-Staple™ technology portfolio represents a comprehensive set of endostapling reloads designed to work in harmony with the natural properties of tissue. And now that performance can be optimized with the only fully-powered endostapler, Covidien's reusable iDrive™ Ultra powered stapling system. With one-handed, push-button operation, it enables an unprecedented level of precision, even in challenging variable tissue. This is intelligent compression…optimized by power.

Tri-Staple™ technology reloads are designed to work in harmony with the natural properties of tissue to optimize performance before, during and after stapling. With its stepped cartridge face, Tri-Staple™ technology delivers graduated compression, optimizing interaction between the tissue and stapler because it:

The improved design of the stronger fixed anvil and I-beam incorporated into the Tri-Staple™ technology reload results in improved staple line strength, leak resistance and hemostasis when compared to the Universal Reloads3.

No single stapler can address the wide range of tissue management issues surgeons face on a daily basis. That's why Covidien has developed a portfolio of specialty stapling solutions within the Tri-Staple™ Technology portfolio to provide the right tool to meet each specific challenge.

Below and Beyond in LAR

Setting new standards for access, maneuverability and staple line security in LAR procedures, the Endo GIA™ Radial Reload with Tri-Staple™ technology allows surgeons uncompromised access and visibility in the deep pelvis. Surgeons can operate with confidence across a broader range of tissue thickness and lower in the pelvis compared to Ethicon Contour®*1

Access Without Compromise


  • The Endo GIA™ Radial Reload with Tri-Staple™ technology delivers unprecedented access and ease of use.
  • It has the potential to get 1-2 cm lower in the pelvis compared to the Ethicon Contour®*1

Facilitation of Better Distal Margins


  • The narrow profile and unique geometry improves visualization in the pelvis when compared to Contour*.

1. Pelvic depth, access, and rectal transection comparative human cadaver study sponsored by Covidien in May 2010 comparing the performance of the Endo GIA™ Radial Reload with Tri-Staple™ technology to the Ethicon Contour® Curved Cutter Stapler. Statistically significant results in both coronal and sagittal planes (data on file).

In Extra-Thick Tissue, Anything Less Just Comes Up Short

Consistent staple formation can be challenging, especially in thick tissue bariatric and thoracic applications, such as laparoscopic sleeve gastrectomies or wedge resections. The Endo GIA™ Black Reload with Tri-Staple™ technology was designed to provide superior staple formation1 and strength2 in thick tissue applications.

Superior Staple Formation1

Excellent Staple Formation

  • The only 5.0mm staple height - tallest on the market
  • In head-to-head comparisons, the Endo GIA™ Black reload with Tri-Staple™ technology outperformed the Echelon Flex™ Green in thick tissue1

Consistent Performance in Thick Tissue

Strength Test

  • Thickest indicated tissue range for any stapler on the market (2.25 mm – 3.00 mm)3
  • A new knife blade with every firing ideal for thick tissue applications
  • Designed to handle variable tissue thicknesses

Superior Staple Line Strength2

Strength Chart

  • Superior staple line strength compared to Echelon™ and Endo GIA™ Universal™ stapling products2
  • More than double the strength compared to the Echelon™* green reload4

1. Staple line evaluation of two staple designs (Endo GIA™ Black 60mm reloads with Tri-Staple™ technology and Echelon Flex™* Green 60mm reloads) in explanted porcine stomachs.
2. Tri-Staple Technology Bench Top Testing; Tyvek Pull Apart Testing; Data on file.
3. Indicated tissue thickness range: Endo GIA™ black reload (2.25mm to 3.00mm) vs. Echelon Flex™ green reload (2.00mm)
4. Staple lines were fired into Tyvek® media and pulled apart until failure (n=10). These tests demonstrated that the Endo GIA™ with Tri-Staple™ technology provides superior staple line strength compared to Echelon™ and Endo GIA™ Universal™ stapling product. The Endo GIA™ axt black reload with tri-staple™ technology has more than double the strength compared to the Echelon™ green

When Challenging Anatomy Throws You a Curve, Respond with Your Own

The unique Endo GIA™ Curved Tip Reload with Tri-Staple™ Technology is the only stapler designed with a curved tip at the distal end of the anvil to provide enhanced visibility and maneuverability around target tissues and vessels.

Visualization, Dissection & Manipulation

  • Gold curved tip provides enhanced visualization of anvil.
  • Atraumatic curved tip can be used for blunt dissection
  • Radiopaque Flexible Introducer* designed to guide the fixed anvil around target tissues/vessels

Potential for O.R. Time Savings

Clinical Paper

  • In a retrospective study of 45 patients, the curved tip was associated with better time savings during thoracoscopic lung resection procedures1.

It Comes Up Big when You're Working In Tight Spaces

The 30 mm Reload with Tri-Staple™ technology is the only reload designed specifically for use in situations where space is limited. Its extra-short design provides unprecedented access and maneuverability in the tightest of cavities while still delivering the performance of Tri-Staple™ technology.

  • The 30 mm length was designed to provide ease of use in MIS procedures and enables improved access and maneuverability in tight cavities.
  • The 30 mm reload is also available in a curved tip option, facilitating improved access to vessels and anatomical structures in small cavities, such as vascular applications.

Endo GIA™ Ultra Universal Handle: One Size Fits All Reloads

Benefit from inventory efficiencies and an improved user experience delivered from the universal handle platform. Endo GIA™ Ultra Universal staplers can be used with all existing Endo GIA™ Universal reloads and Endo GIA™ reloads with Tri-Staple™ technology. Three shaft lengths deliver greater flexibility for procedure-specific use.

Delivering Results to the Bottom Line: Achieve SKU Standardization

According to a 2010-2011 IMS database analysis, the Covidien stapling platform provides significant opportunities to drive efficiency, resulting in SKU standardization and reduced carrying costs.

Universal Platform and Tri-Staple™ Technology Efficiencies:

  • 14% fewer handles used when compared to Ethicon1
  • 69% total SKU reduction2
  • 37% reduction in stocking levels3
  • 37% reduction in inventory footprint2
  • 54% reduction in excess waste2

1. Handle waste reduction calculation based on number of handles used for 500 total cases between July 2010 – July 2011 for Ethicon and Covidien respectively. Assumes 1 = Covidien handle needed per case.
2. Total SKU reduction, inventory and waste based on national annual Covidien and Ethicon reload and handle usage reported by IMS (July 2010-2011)
3. Assumes a 2-5 day supply of product in storage, based on focus group research findings during the August 2011 meeting of The Association of Healthcare Resource and Materials Management (AHRMM).
