It was reported that the procedure was to treat a lesion located in the superior mesenteric (sm) artery that was mildly calcified, heavily tortuous and 70% stenosed.While advancing the 6.0x29mm omnilink stent delivery system over a non-abbott wire, resistance from the tortuous anatomy was noted and the stent dislodged from the delivery system.The devices were removed and the stent snared and removed from the anatomy.There was no adverse patient sequela and no clinically significant delay.A 7x29mm omnilink elite stent was then deployed to complete the procedure.No additional information was provided.

A visual inspection was performed on the returned device.The reported difficult to advance could not be tested due to the device condition.The reported device dislodge or dislocated was confirmed.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 incidents/complaints from this lot.The investigation determined the reported difficulties and subsequent treatment appear to be related to the operational context of the procedure.Additionally, the reported removal of foreign body was due to a dislodged stent removed from the anatomy.There is no indication of a product quality issue with respect to manufacture, design, or labeling; therefore, no product-related corrective action will be implemented in this case.
