Manufacturer Narrative

The pipeline pushwire was returned for evaluation without the pipeline braid.The pushwire was observed and found to have a bend within the capture coil and at 25.0cm from the distal tip coil.No other anomalies were observed.Based on the analysis findings the clinical observation could not be confirmed.The pipeline braid was not returned for evaluation, therefore any contributing factors from the pipeline braid could not be assessed.We are unable to definitively determine the cause for the reported experience.It is possible that the "pushwire bend" within the capture coil may have contributed to the reported experience.However, the cause for the damages could not be determined.Per the pipeline instructions for use (ifu): ¿detachment can be facilitated by slowly rotating the delivery wire in the clockwise direction and/or manipulating the microcatheter by locking down the delivery wire and moving both as a system.If the capture coil tip of the delivery system becomes stuck in the mesh of a delivered ped, rotate the wire clockwise while advancing the wire to try to release it, then slowly pull back on the delivery wire in addition, the lot history record of the reported lot number has been reviewed.The lot history record review showed no discrepancies that would have contributed to the reported experience.All products are 100% inspected for damage and irregularities during manufacture.
