Airway stents.
Considerable progress has been made since the initial stents were manufactured. Despite the reported side effects, cumulative evidence suggests beneficial effects in properly selected patients. The technology is still in evolution, and design modifications strive to find the perfect stent. The Dumon stent remains the gold standard against which the functions of all other stents are being measured. Unfortunately requirement for the RB for deployment has restricted widespread application at least in the United States. The Wallstent can be inserted using FB and has a great potential among the metal stents. Its biggest drawback is that once inserted it is difficult to remove. Studies with the nitinol Ultraflex and the polyester/silicone Polyflex prototype stent also show promise, although extensive experience and long-term follow-up data are still not available. It is possible that combining the strength of the tube stents with the flexibility of the metal stents may one day help to develop the ideal stent.
