The Stening® Class LSD Stent is a device designed to maintain the clearance of the airway in sufficient conditions for ventilation. It has a side hole that allows ventilation of the right upper lobe.
It has a conical elastic tubular structure, with non-slip spurs arranged in several rows and distributed symmetrically along its 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 LSD 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.
Neoplasms in right or intermediate source bronchus that do not affect the upper lobe
Neoplasms that invade tracheal carina or its slopes
Following laser photorecorder, cryotherapy or electrocautery, to maintain the opening of the airway
Postinfectious stenosis (tuberculosis, histoplasmosis with mediastinal fibrosis, herpes virus, diphtheria)
Post-terminal surgical bronchial anastomosis stenosis
Excessive dynamic compression of the airway
Invasion of bronchial sources by esophageal carcinoma
After endoscopic resection of bronchial metastases
