The device was not returned for evaluation.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.The investigation determined that the reported difficulties and subsequent treatment appear to be due to operational context of the procedure.It is likely that the clearance between the inner diameter of the sheath and the absolute pro self expanding stent system (sess) shaft was reduced, likely due to kink or anatomical conditions, and as a result, the stent was unsheathed resulting in deployment.Additionally, the difficulty removing, and stent separation was the result of pulling the sess back into the introducer sheath with the stent partially expanded against the vessel wall.The absolute pro instruction for use (ifu) warns: should unusual resistance be felt at any time during lesion or stricture access or delivery system removal, the introducer sheath / guiding catheter and stent system should be removed as a single unit.Applying excessive force to the stent delivery system can potentially result in loss or damage to the stent and delivery system components.In this case, the resistance was related to procedural circumstances and the force required to remove the delivery system was required.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.Exemption number e2019001-permits numbering sequence to begin with 10000, to avoid duplication of report numbers due to process transition.There may be gaps in numbering for reports submitted during the transition period.
