Manufacturing date ¿ added.Device evaluated by mfg ¿updated.Summary attached - updated.Expiration date - added.Product available to stryker ¿ updated.Returned to manufacturer on ¿updated.The device history record (dhr) review confirms that the device met all material, assembly and performance specifications.Visual inspection revealed that the delivery wire was kinked/bent most likely due to the handling of the device.The main coil was not returned for analysis and the main coil was found to be detached due to a physical break at the detachment zone.There was procedural fluid was noted on the device as well.Functional testing could not be performed due to the damaged condition of the returned device.Information available indicated that continuous flush was not maintained during the procedure.It is likely that insufficient flush contributed to the damage noted to the device and to the reported issue.As per the device direction for use(dfu), "in order to achieve optimal performance of the target detachable coil system and to reduce the risk of thromboembolic complications, it is critical that a continuous infusion of appropriate flush solution be maintained between a) the femoral sheath and guiding catheter, b) the 2-tip microcatheter and guiding catheters, and c) the 2-tip microcatheter and stryker neurovascular guidewire and delivery wire.Continuous flush also reduces the potential for thrombus formation on, and crystallization of infusate around, the detachment zone of the target detachable coil." based on the information available, an assignable cause of use error was assigned to this event.
