Bare-metal tracheal/bronchial stent

A bare-metal tracheal/bronchial stent is a non-bioabsorbable tubular implant designed to be placed in the trachea or bronchi to keep the airway open when it is narrowed or blocked due to disease, trauma, or tumor growth. It maintains luminal patency by providing structural support, allowing airflow and secretion clearance, and is used in patients with malignant or benign central airway obstruction.

These devices are typically made of metals such as stainless steel or nitinol and are delivered via catheter-based systems, often expanding in place through self-expansion or balloon dilation. They are supplied as sterile, single-use implants and may include disposable delivery tools; regulation focuses on their structural integrity, biocompatibility, and performance as implantable airway support devices without drug or biological components.
