Stening® Class Stent
The Stening® Class Stent is a device designed to maintain the clearance of the airway in sufficient conditions for ventilation. It has a double conical elastic tubular structure, with non-slip spurs of linear arrangement arranged in several rows and distributed on its diametral and symmetrically opposed surface.
To accompany the functionality of the bronchus and its physiology, the strength of its wall is progressively reduced distally at a rate of 3% per each centimeter of the length of the stent.
Increase in fixing capacity:
Although the increase in the fixing capacity of the Stening® Class Stent can not be precisely determined with regard to its counterpart, this property is benefited by the existence of fixations aligned against the direction of possible unwanted displacement. Their number duplicates the existing ones in the straight stent model.
