Manufacturers ref# (b)(4).Summary of investigational findings: the filter would not release from the delivery system.Device was retrieved and another filter was successfully placed.No harm to patient reported.The jugular introducer inside the sheath was returned with the detached tulip filter.On the jugular introducer the red safety button was pressed down, ie the system was unlocked, but no nonconformances were noted.Some dents were noted in the most distal sheath tip.The filter was found according to specifications and could be attached to the jugular introducer and released from same without difficulties.Based on these findings the exact reason for the difficulties encountered when attempting to release the filter cannot be determined, but the ifu caution that excessive tension during deployment may prevent the filter from releasing, when the release mechanism is activated.It was assessed that because any discovered non-conformances were 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.
