Manufacturer ref# (b)(4).Summary of investigational findings: while the physician was advancing the filter catheter out of the sheath and retracting it into the sheath to adjust the filter position, the filter became detached from the filter catheter, then placed in an undesired site.Therefore, the filter was retrieved with a snare device.The physician considered to replace the filter though, he decided to abandon filter placement itself due to the amount of thrombus and its location.The procedure was finished without placing the filter.The jugular introducer was returned for device evaluation.Per device evaluation: the jugular introducer was curved, and the red safety button was pressed down.No damage was observed on the sheath tip.It was observed that the grasping hook has been straightened.A test filter could be attached and detached from the jugular introducer, but the straightened grasping hook did not grasp the filter hook completely.The cause for the reported failure cannot be determined, based on the device evaluation.The observation that the grasping hook has been straightened is seen before, if the filter is pulled back during attempts to resheath it.According to the instruction for use excessive force should not be exerted in placement of the filter and ifu also describes: if the filter is not in the desired position, carefully advance the introducer sheath over the filter until right before the anchors.Reposition the system as desired, and again withdraw the introducer sheath and protection sheath until the protection sheath and jugular introducer handle are in contact with one another, completely exposing the filter.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 final inspection, there is evidence that the dhr was fully executed.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 21 cfr 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.
