The device history record (dhr) review confirmed that the device met all material, assembly and performance specifications.Only the delivery wire was returned without the coil.Visual examination of the returned device revealed that target coil delivery wire was kinked/bentlikely due to handling.In addition, the main coil appeared to have physically detached from the delivery wire.Functional testing could not be performed on the returned device due to the condition in which it was returned.Follow up attempts were made to the customer to obtain additional information associated with the returned device; however, no further information is available.Information available indicated that the coil could not be advanced through the microcatheter (unknown manufacturer).Based on the information available and analysis of the returned device, the exact cause for the observed detachment of the coil from the delivery wire cannot be determined.
