Stent retrieval device

Abstract

Abstract This invention is a device (50) and method for retrieving partially deployed balloon expandable stents. A shaft (54) has a grasping device (52) at its distal end and includes a mechanism for opening and closing the grasping device. The grasping device may include a reinforced tube (52) having a bound outer inflatable sleeve (76) and a longitudinal slit (58). The grasping device is inserted over a guiding balloon catheter (22) and inflated to grasp the end of a stent. The stent can then be retracted into the guide catheter. The grasping device may alternatively include fingers (202) with distal end attached to an inner shaft (212) and proximal ends attached to an outer shaft (214).The fingers open by relative sliding of the two shafts.
