Endo GIA™ Radial Reload

The Endo GIA™ Radial Reload’s design and mechanism of action significantly reduces the likelihood that the staple line will contain “dog ears.” This is due to the following reasons:

• Tissue Compliance: When tissue is allowed to relax during the firing sequence, the result is a straighter staple line. Unlike the Contour®, the Endo GIA™ Radial Reload does not force tissue to comply with the geometry of the stapler. The Contour® utilizes a rigid pin that is deployed to fire the device and forces the tissue to comply with the device. Containing the tissue within the device in this manner can result in excessive tissue compression/stress and poor staple formation that may have a detrimental effect on clinical outcomes.¹


• Tissue Compression: The Endo GIA™ Radial Reload incorporates the same clinically proven I-Beam technology as our linear staplers. During the firing sequence the I-Beam applies progressive compression, with each stroke of the handle. This promotes gradual tissue relaxation and dispersion of interstitial fluids. The Contour® incorporates a “guillotine” like, acute compression along the entire staple line. This acute compression does not allow the tissue to gradually comply with the device and causes high forces/stress within the tissue.^2,3

The “shipping wedge/load lock” is a safety feature of the device that ensures proper loading of the reload onto the handle. It prevents accidental pre-firing of the instrument, which could result in wasting a reload due to lock-out.

The Endo GIA™ Radial Reload has a 60 mm staple line and a 55 mm cut line.

To date, clinical experience with the Endo GIA™ Radial Reload has shown that only one firing has been needed in the majority of cases. For the cases where the tissue is too thick for the reload, a second stapling is required (i.e. single application Endo GIA™ Radial Reload + 30 mm or 45 mm reload of the same color/staple size).

Yes, the Endo GIA™ Radial Reload can be used laparoscopically. To date, surgeons have had clinical success using the Endo GIA™ Radial Reload through an existing trocar incision in the following manner:

1. Surgeon removes port (15 mm standard length trocar)


2. The 15 mm standard trocar is “back-loaded” onto either a standard or XL length Endo GIA™ Ultra handle


3. The Endo GIA™ Radial Reload is then loaded onto the handle and the load lock is removed


4. After properly cycling the instrument, the Endo GIA™ Radial Reload is “horse-shoed through the existing trocar incision


5. Once the Endo GIA™ Radial Reload is in the abdomen, the trocar can be moved back down into the incision


6. After transection of the tissue, the Endo GIA™ Radial Reload is removed from the abdomen with the trocar (the reload and handle still attached)


7. The Endo GIA™ Radial Reload can then be unloaded


8. The surgeon re-inserts the trocar into the abdomen

Note: This technique should not be attempted with a standard length Endo GIA™ Universal handle (legacy handle) – the “unload” button will be covered by the trocar and the surgeon will not be able to unload the Radial Reload after use.

The Endo GIA™ Radial Reload does not have an articulation feature. Itis compatible with our Endo GIA™ Universal and Endo GIA™ Ultra Universal handles. These handles can accommodate all of our reloads (straight and articulating reloads). The articulation knob is meant to work with our articulating reloads only.

The Endo GIA™ Radial Reload does cut and staple simultaneously. By design, staples are always deployed in front of the knife blade to ensure proper hemostasis.

Yes, the Endo GIA™ Radial Reload is compatible with all our Endo GIA™ Universal and Endo GIA™ Ultra Universal handles.

Note: The backloading technique should not be attempted with a standard length Endo GIA™ Universal handle (legacy handle) – the “unload” button will be covered by the trocar and the surgeon will not be able to unload the Endo GIA™ Radial Reload after use.

Yes, the Endo GIA™ Radial Reload is currently indicated for the following applications:

The Endo GIA™ Radial Reload with Tri-Staple™ technology has application in open or minimally invasive general abdominal, gynecologic, pediatric and thoracic surgery for resection and transection of tissue and creation of anastomosis, as well as application deep in the pelvis, i.e. low anterior resection. It may be used for transection and resection of liver substance, hepatic vasculature.

It was designed to maximize control while placing the reload around target tissue. The tissue retaining feature aids in the capture of tissue and prevents it from extruding during placement. It is atraumatic, so if a second firing is required it will not damage tissue.
