The AWC® is an endoscopic system for providing an additional working channel for flexible endoscopes.
The AWC® can be used for a variety of applications:
- EMR+: Resection of lesions with a combination of snare and anchor/grasper
- ESD+: Dissection of lesions with a combination of grasper and knife or Coag Dissector
- Clip removal: facilitated removal of OTSC® clips with the help of grasper and DC Cutter
- Bleedings (additional lumen for suction and flushing)
- Additional instrument; interesting for a variety of applications

Positioning of snare and OTSC® Anchor or FTRD® Grasper
Elevation of the lesion and snare closure
Push-back* of the OTSC® Anchor or FTRD® Grasper while snare stays closed and subsequent resection
*Note: Anchor needles must not be captured with the snare during the push-back move. If in doubt, the anchor needles can be closed to avoid a short circuit.
