The DST Series™ EEA™ OrVil™ 21 mm device is a DST Series™ EEA™ 21 mm anvil assembly, and the DST Series™ EEA™ OrVil™ 25 mm device is a DST Series™ EEA™ 25 mm anvil assembly, both with the anvil head secured in the tilted position.

The anvil assembly is mounted on a 90cm long PVC delivery tube and is secured to the tube with a suture. When used with the DST Series™ EEA™ XL 21 or 25 mm stapler, a circular, double staggered row of titanium staples is placed. Immediately after staple formation, the stapler knife blade resects the excess tissue, creating a circular anastomosis. The diameter of the staple line is 21 mm or 25 mm, depending on the device selected.

The EEA™ OrVil™ anvil is permanently affixed to the center rod and cannot be removed from the center rod.
