Manufacturer Narrative

The pusher was returned for analysis, limiting the scope of the investigation.The distal end of the pusher had been broken off and was not returned for analysis.The pusher was found to be bent in multiple locations throughout the hypotube.It cannot be determined if this damage to the hypotube was present prior to the return shipment for investigation.The transition section of the pusher was found to be broken; however, it cannot be determined if this damage occurred during shipment return or during the procedure.The distal side of the returned portion of the pusher was found to have a stretched body coil.The coil was elongated into a single strand.The coil was broken and the distal end missing.The green lead wire was also found to be broken.Based upon the investigation analysis and available information, the reported complaint was able to be confirmed.The pusher was found to be broken upon return from the field.The pusher was found to be stretched at the distal end of the returned portion of the pusher.No definitive root cause can be determined.The microcatheter and caught portion of the pusher were not returned limiting the scope of the investigation.Historically the observed damage is the result of a pusher/implant that is caught in the microcatheter upon retraction.
