Manufacturers ref# (b)(4).Summary of investigational findings: based on the event description, it is assumed that the medical staff loaded the femoral filter introducer with the filter into the introducer sheath, where they met resistance and could not advance the filter.The medical staff pulled therefore the introducer with the filter out and the hook, which is assumed to be a hook of a secondary filter leg, was straight.The procedure was completed with a new set of the same type device.No adverse effects on the patient have been reported due to this occurrence the complaint device was not returned and no photos are available.It is was therefore not possible to conduct a device failure analysis for this investigation.A kinked introducer sheath can lead to difficulty in advancement of filter introducer through the sheath, however, it is unknown if the sheath of the complaint device was kinked.Furthermore, ifu states that the preloaded filter should not be rotated inside the introducer system, and that excessive force should not be exerted to advance the filter through the introducer system.It could be possible that the user exerted excessive force and rotated the preloaded filter inside the introducer, when resistance was met, which could have led to the reported event where the hook straightened.However, this is not clear or described in the event description, and the cause for the reported event can therefore not be established due to insufficient/limited information.There are adequate controls in place to ensure the device was manufactured to specifications.It was assessed that because no non-conformances were detected, there is evidence that the dhr was fully executed.In addition, no other lot related complaints have been received from the field.It is therefore concluded that there is no evidence that nonconforming product exists in house or in field.Cook medical will continue to monitor for similar events.This report is required by the fda under 21cfr part 803.This report is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement made in it is intended to be an admission that any cook device is defective or malfunctioned; that a death or serious injury occurred; or that any cook device caused or contributed to; or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
