3. Either manually advance the retaining pin using the actuator button on top of the handle to capture the tissue

within the jaw opening (A), or automatically advance the retaining pin by partially squeezing the closure
trigger (B). In the intermediate position, the retaining pin is fully seated in the anvil capturing the tissue, and the
jaws are partially open, allowing for desired placement of tissue. Note that there is an audible click halfway
through the closure stroke indicating that the device is in the intermediate position.

Device preparation and placement

1. Remove the staple retainer from the instrument

by pushing on the pad labeled “Push to Remove.”

2. Position tissue to be cut and stapled between the anvil and the cartridge. If the tissue doesn’t it comfortably

within the jaws, you should consider two irings.

Device is reloadable to complete a single transection with multiple irings when needed. Any tissue covering
the hole in the anvil will be pierced by the retaining pin. The knife extends to the retaining pin and the staple
line extends beyond the pin supporting multiple irings.

Caution: To prevent premature iring, do not grasp the iring trigger.

4. Squeeze the closure trigger until latched, listening

for an audible click. After closing, holding the jaws
in place for 15 seconds prior to iring may result in
better tissue compression and staple formation.

To reposition tissue, open the jaws by squeezing
the handle and closure trigger together slightly,
and push the release button.
