Polymeric laryngeal stent

A polymeric laryngeal stent is a sterile, non-bioabsorbable implantable device designed to be placed in the larynx to prevent or treat laryngeal stenosis and chronic aspiration following surgery. It is typically constructed from synthetic polymers such as silicone, shaped as a hollow, semi-soft structure that conforms to the inner surface of the larynx to maintain airway patency and support healing.

Devices in this category are supplied as sterile, single-use implants intended for surgical implantation. Disposable tools or accessories that assist in the placement of the stent may be included within the category definition, but the stent itself is not reusable and does not contain bioactive or drug-eluting components.
