Product complaint # (b)(4).Section b5: additional information received indicated that the final placement of the detached pulserider adequately covered the neck of the aneurysm and kept the coils inside the aneurysm sac.The device(s) were used and prepped as per the instructions for use.Section e1-- initial reporter phone: (b)(6).A supplemental report will be submitted if new facts arise which materially alter information submitted in a previous mdr report.Complaint conclusion: as reported by the filed, a pulserider t aneurysm neck reconstruction device (4mm, 8mm arch) was used with a prowler select plus microcatheter (mc) for bifurcations of the internal carotid aneurysm.At the end of the procedure, it was attempted to be detached with a cable (prdsace 30393939).The proper indicator for detachment was confirmed and the complaint device was retracted slowly but the complaint device was fallen drop approximate 1 or 2 mm and it was detached at the same time.This complaint device seemed not to have been detached completely.The procedure was completed by making body filling.The coil was coved the blood vessel of the bifurcation slightly but there were no complications.The pulserider was used as per the instructions for use (ifu).Additional information received indicated that the final placement of the detached pulserider adequately covered the neck of the aneurysm and kept the coils inside the aneurysm sac.The device(s) were used and prepped as per the instructions for use.The device remains implanted; therefore, it is not available for analysis.A review of manufacturing documentation associated with this lot w3382-04 presented no issues during the manufacturing or inspection processes related to the reported complaint.With the information available and without the product available for analysis, the reported customer complaint of ¿failure to detach¿ could not be confirmed.Based on the device history record review, there is no indication that the event is related to the device manufacturing process.Failure to detach is a known potential issue associated with the use of this device.The instructions for use (ifu) contains several precautions related to this issue and includes instructions for troubleshooting the situation should it be encountered during use.Assignment of root cause for the event remains speculative and inconclusive, based on the limited information provided and without the return of the complaint device; however, it is possible that clinical and procedural factors, including device manipulation / interaction, vessel characteristics, device selection, and the concomitant microcatheter, may have contributed to the reported issue.As part of the post market surveillance program, information from this complaint is trended to identify statistical signals for consideration of further correction action.Since there was no evidence to suggest the event was related to a manufacturing or design issue, no corrective actions will be taken at this time.
