Stening® Solid Stent MS03
Solid radiopaque biocompatible silicone device intended for bronchial occlusion in the treatment of bronchopleuropulmonary conditions such as bronchopleural fistula and persistent air leak.
Product code: MS03
Stening® Solid Stent MS03
Code MS03
The Stening® Solid Stent is made of silicone and intended for bronchial occlusion in the treatment of various bronchopleuropulmonary conditions, such as bronchopleural fistula and persistent air leak in cases of pneumothorax that cannot be treated with conventional surgery.
It is available in 3 different units — MS810, MS911 and MS1012 (see sizes). The device is radiopaque (white).

Clinical indications
The Stening® Solid Stent MS03 is indicated for bronchial occlusion in various bronchopleuropulmonary conditions.
- Bronchopleural fistula
- Stump suture failure after pulmonary or lobar resection
- Occlusive bronchial treatment
- Hemoptysis
- Medical-grade silicone
- Beveled edges to prevent granulomas
- Spur system to prevent migration
- Removable
- Maximum-smoothness surface to prevent adhesion of secretions
Available dimensions
The Stening® Solid Stent MS03 comes in three references — MS810, MS911 and MS1012 — allowing selection of the most suitable size for the fistulous orifice or the bronchus to be occluded.
Due to the characteristics of the manufacturing process, device measurements are subject to a variation of +/- 2%. For specific inquiries about instrumentation, bronchoscopes or forceps, contact us at (+54) 11 4553-5070 or (+54) 11 4551-2333.
How to use
The Stening® Solid Stent is implanted with the aid of a rigid bronchoscope, and general anesthesia is required.
Once the placement site and its size have been determined — established by comparison with the known diameter of the endoscopic instrument being used — one or more solid stents of the appropriate provided sizes will be chosen, exceeding the diameter of the fistulous orifice or the bronchus to be occluded, so that it fits the bronchus or stump in which it will be lodged.
The device has a flat tab at its posterior end, from which it is grasped with an alligator-type rigid bronchoscopy forceps.
The forceps-stent assembly is then introduced through the bronchoscope to guide it to its final destination in the bronchus or fistula to be occluded, inserting the Solid Stent into the orifice.
The entire described procedure is performed under direct vision using the bronchoscopy optics.
Removal is carried out by performing the reverse maneuvers.
Due to its radiopaque properties, it can be identified on radiographs.
Post-implant care
Recommendations for the follow-up of the patient with the Stening® Solid Stent MS03.
- Maintain moisture of secretions when present, performing frequent nebulizations with warm isotonic saline solution.
- Periodic monitoring at the physician’s discretion.
Warning
Important
This type of device may undergo unexpected displacement. This will depend on an incorrect choice of stent caliber relative to the bronchial or fistulous orifice in which it has been lodged, as well as the unpredictable individual reaction of the tissue that acts as support in the implant area. A device that has migrated may be expelled by coughing or accidentally lodge in another bronchus of the same lung or the adjacent one, causing an undesired bronchial occlusion that could lead to severe ventilatory failure followed by death.
Displacement of the occlusion device toward the pleural cavity is possible in cases of post-pneumonectomy fistula, as well as its spontaneous expulsion through an existing pleurocutaneous window.
An abnormal position may be suspected by the appearance of sustained coughing. The devices are radiopaque and their position can be identified on chest radiographs. A displaced device must be removed by the interventional physician.
The device must not be reused, in order to avoid causing cross-contamination.
