Over the last 40 years, digestive endoscopy has moved from purely diagnostic endoscopy to simple therapeutic endoscopy then to more complex surgical endoscopy. Recent progresses are now aiming at specific indications using only natural orifices. This requires medical devices more complex than the ones commonly available today.

To make these treatments possible, a triangulation system (ie: a system that allows to operate with and angle relatively to the axis of the endoscope) within the digestive tract is necessary. Currently, gastroenterologists are limited in their surgical possibilities as traditional endoscopes have their therapeutic channels ‘locked’ in the endoscope axis, making the gastroenterologist one-handed. A triangulation system permits to orient instruments relatively to each other, which provides the degrees of freedom used when a surgeon uses his hands. The gastroenterologist can hence make a stitch or raise a tissue to improve lesion visibility. This permits true transoral surgery and this is why Endomina has been developed.
