Stening® Cone MD Stent

Code MD

Description

This stent is especially destined to impede or reduce the oesophageal fluids path to the airway. These fluids pass through the fistulas and communications among the airway and the digestive system. It is especially frequent when the main left bronchus is invaded by an oesophageal carcinoma.

Its distal margin is bevelled at an angle of 45º and the proximal one engrosses into a cone shape, in order to fix in the carinal side and the tracheal wall.

The Stening Cone Stent lacks of anchors. Its smooth walls permit a complete touch with the bronchial mucosa in all its extension.

It is also useful in other affections that take place in the large bronchi, such as scarring stenosis, and those secondary to termino-terminal anastomosis, in bronchial reimplantations and bronchial complications of lung transplantation.

It can be used to replace a straight stent, after the treatment of large bronchi occlusions due to bronchogenic carcinoma or bronchial locations of other carcinomas.

  • Abnormal bronchoesophageal communication due to carcinoma of the esophagus.
  • Bronchoesophageal post-traumatic communication.
  • Bronchial stenosis.
  • After the resection of the carcinoma in a source bronchus.
  • Traumatic bronchial rupture.

The Stening® Cone MD Stent can be inserted with a large bronchoscope or with an applicator.

If an applicator is available, it consists of two telescopic metal tubes of different lengths.

Insert the optics inside the applicator, then collocate the Stening® Cone MD Stent at the end of the applicator, as shown in the photograph. The bevelled end of the Cone should be on a distal position and oriented so that its oblique end faces the entrance of the superior bronchial lobe.

Perform the orotracheal intubation with the optical-introducer-Stening® Cone Stent assembly, under direct endoscopic vision. Move towards the affected source bronchus, guiding the assembly inside the trachea until you reach the source bronchus. When you reach the affected area, advance until you surpass the distal end of the fistula or bronchial injury over one centimetre.

Then, keep the external tube of the introducer immovable and gently remove the internal one together with the optics.

The Stening® Cone Stent will be released inside the bronchus. Remove the applicator and intubate the airway again with a conventional bronchoscope to perform an inspection.
