Abstract

An airway stent with an integral suture anchor is used to prevent migration of the stent within the airway. The suture anchor is incorporated by percutaneous placement of a suture through the neck and into the stent. The distal end of the suture includes an anchor element to secure the suture to the stent. The opposite end of the suture is tensioned and held in place by a suture clamp and a pledget routed over the stent and placed against the neck. Airway stents such as tracheal stents are effective at maintaining airway patency however; a common complication is stent migration. The integral suture anchor provides a reliable, economical, and non-intrusive solution to stent migration.
