The device history record review confirms that the device met all material, assembly and performance specifications.During visual inspection, the proximal contact wire was intact.The coil delivery wire was intact.The coil was stuck in the catheter hub and couldn't be removed.The detachment area can be seen.No other anomalies were noted.Functional testing could not be performed due to the condition of the returned device.Based on device analysis, the coil was found jammed and prematurely detached.In the case of this complaint, it is most likely that anatomical or procedural factors resulted in the target coil becoming jammed in the micro catheter and eventually detached when trying to remove.Therefore, an assignable cause of procedural factors has been assigned to this investigation.
