It was reported that the procedure was to treat a moderately calcified lesion in the moderately tortuous iliac artery.A 7.0x39mm omnilink elite balloon expandable stent system (bes) was advanced to the lesion with resistance due to the stenosed anatomy, when the stent was noted to be dislodged from the balloon but not completely separated.The bes was removed, a snare was used to ensure the removal of the partially dislodged stent and the procedure was abandoned.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

The device was returned for evaluation.Visual analysis was performed on the return device.The reported stent dislodgment was confirmed.The difficult to advance was not confirmed as it was related to procedural conditions.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other complaints reported from this lot.Based on the information provided, the reported difficulties appear to be due to procedural circumstances.The resistance during advancement was likely due to interaction with the anatomy.Advancing against resistance likely caused the stent to dislodge.The additional treatment to snare the dislodged stent was due to case circumstances.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
