Stening® ROLL Conical stent for minor bronchi
The Stening® ROLL is the Stening response to the clinical need on carrying out diseases treatments for small bronchi, but that are still capable of providing ventilation to its distal segments. This can be seen in the neoplastic infiltrations in the lower lobar bronchi both right and left ones.
In this way, the interventionist and therapeutic bronchoscopy extends its scopes and Stening accompanies it with the development of devices that can be applicable in minor bronchi. As well as in peripheral ones and those with low resistance on their thin walls. These force the experts’ skills to increase the scopes of the intravenous surgical treatments of the airway.
The Stening® ROLL is a special stent for common trunk of the basal segments of the lower lobes (left and right).
Due to this, the stent possesses smaller anchors and a larger distribution that provide a smooth support and with more distribution points of its loads. So that, its short dimensions make possible its fitting inside the bronchus that is going to be treated. Its anatomic shape copies the bronchus’ conical shape, avoiding the distortion produced by the classical stents with a cylindrical shape.
The measure of preference is detailed on the ROLL911, with a distal external diameter of 9 mm and a proximal one of 11 mm. The length is 20 mm.
For the individual anatomic variations we have two more types: the ROLL810, with a length of 20 mm and the ROLL1012, with a length of 25 mm. The last one is a special one for the intermediate bronchus. It permits the air flux without occluding the apical entrance of the lower one, when this segment is unscathed. In this way, it is possible to effectuate treatments on the intermediate bronchus without interfering with the ventilation of other segments.
The Stening® ROLL can be cut on their margins to fit the length of the bronchus where they are implanted. Effectuate the section on its proximal margin, because this one does not confront any bronchial spur during the respiratory dynamic.
A stent implant inside the common trunk of the lower lobar can end in an occlusion on the entrance of the apical segment. The doctor must evaluate the benefits of restoring the ventilation of the basal ones in spite of the loss of the apical from the lower one. This must be done when this last one would not be affected by the neoplastic disease.
Stening® provides detailed instructions for use with each device, including insertion and removal techniques, precautions, and postoperative care.
