Esophageal stent for the dynamic treatment of benign esophageal stenosis

Dynamic Stent is the ideal device for the dynamic conservative treatment of benign esophageal stenosis. Particularly in esophageal stenosis generated by ingestion of caustic substances or outcome of oesophageal 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 STENT FEATURES

Applications

Dynamic conservative treatment of benign esophageal stenosis

Applications

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. It is used to maintain a patent esophageal lumen after an adequate dilation has been obtained. This facilitates the esophageal peristalsis and hence the dynamic movement of the esophageal wall.

Advantages

Continuous mobility of the esophagus

Advantages

Thanks to its unique design, once placed in the stenosis already dilated, the stent enables the transit of food and saliva through the circular chamber between the outer wall of the stent and the inner wall of the esophagus. Innovatively designed compared with other stents currently available which all apply a pressure on the esophageal wall, this device promotes a continuous motility of the esophagus including its dilated scarring portion. Avoiding the compression of the esophageal wall, the OPBG dynamic stent™ prevents the risk of disepithelization and mucosal overgrowth resulting in stent occlusion, as frequently observed with those stents compressing the esophageal wall. As shown in the figures, the stent is coaxially mounted on a nasogastric tube which is properly fixed to a nostril by means of an atraumatic flange. The nasogastric tube prevents the displacement of the stent yet enabling its mobility during swallowing and allowing patient movements. If needed in an early stage, nasogastric part tube can be used to administernutritional solutions using standard, universal protocols.

Description

Nose-gastric silicone probe

Description

As shown in the figures, the stent kit includes a IIFr or |4Fr silicone nasogastric tube featuring a radiopaque line along its whole length and multiple adequately sized holes for delivering nutrition. Its hemispherical distal, tapered end, is completely atraumatic. The device is equipped with a guide wire which allows stent positioning. The stent is firmly secured to the nasogastric tube at a suitable distance from its distal end. Its special design ensures an adequate flexibility in order to avoid the risk of traumatic injuries of the esophageal wall. Thanks to the radiopaque markers, it is possible to monitor the exact position of the stent with respect to the esophageal stenosis, both throughout the positioning procedure and during the permanence in situ of the stent
