Hairpin-trap: A novel stent retrieval technique

We report a novel technique for retrieving lost stents or other equipment from the intravascular space. A hairpin is formed at the distal part of a 0.014 inch coronary guidewire, inserted through the Touhy valve, and used to “hook” the lost stent. The distal tip of the wire is then pulled back into the guiding catheter, where it is trapped by a balloon, forming a “hairpin‐trap.” The entire system is subsequently withdrawn. © 2010 Wiley‐Liss, Inc.
