Oesophageal stent for the dynamic treatment of benign oesophageal strictures.
Dynamic Stent is the ideal device for the dynamic conservative treatment of the benign esophageal stenosis particularly in those generated by in those cases caused by ingestion of caustic substances or when is presence the outcome of esophageal surgery. Its particular function is represented by the maintenance of the patency of the oesophageal lumen, suitably dilated. This situation favors the esophageal peristalsis and therefore the dynamic movement of the esophageal wall.

Dynamic conservative treatment of benign oesophageal strictures
This device is intended to be used for the conservative dynamic treatment of benign esophageal stenosis. In particular, it is indicated for the treatment of esophageal stenosis due to caustic ingestion and surgically-induced esophageal stenosis. Its particular function is to maintain the patency of the oesophageal lumen, appropriately dilated. This situation favors the esophageal peristalsis and therefore the dynamic movement of the esophageal wall.
Continuous mobility of the esophagus
Its configuration, once positioned at the level of the already dilated stenosis, allows the transit of food and saliva, in the circular corona between the outer wall of the stent and the inner wall of the esophagus. This condition, innovative if compared to other current devices act by compressing the esophageal wall. It promotes the continuous mobility of the esophagus, allowing a “training” of the scar tract. The probe also avoids the displacement of the stent itself, while allowing the necessary mobility during swallowing. If necessary in a first phase Through the nasogastric probe it is possible to give nutritional solutions following the standard protocols.
Silicone nasogastric probe
As shown by the drawings, the device is characterized by a silicone nasogastric probe 11 or 14 Fr, equipped with radiopaque line over the entire length and adequate holes for the passage of nutrition. The tapered distal end is absolutely atraumatic. The device needs a special guide wire, necessary for correct positioning. The stent is firmly fixed, at a suitable distance from the distal end, to the probe itself. Its particular configuration ensures adequate flexibility, avoiding possible trauma to the esophageal wall. The visualization of the stent, with respect to the esophageal tract, both in the phase of positioning and in the subsequent phase of permanence in site, is allowed by the presence of the radiopaque markers.
