Manufacturers ref# (b)(4).Summary of investigational findings: the filter got stuck and would not pass through the delivery system during the filter placement procedure, so the filter was not deployed in the body.No adverse effects on the patient has been reported due to this occurrence.An introducer dilator, a jugular filter introducer, an introducer sheath and a celect-pt filter was returned for evaluation.Two small dents were found 5.3 and 5.5 mm from the hub at the introducer sheath, which could possibly be caused by an unknown tool.Furthermore, two narrowing were found on the introducer sheath, which could be due to the kinks.It was only possible to advance the introducer 73mm through the sheath, which is where the legs of the filter in the introducer passes through the first narrowing of the sheath.Ifu states that excessive force should not be used, however, the likely cause for the reported event is most likely due to the kinks on the introducer sheath.There are adequate controls in place to ensure the device was manufactured to specifications.It was assessed that because any discovered non-conformances were properly dispositioned before qc release, 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.
