Manufacturer ref# (b)(4).Summary of investigational findings: it was reported that the filter was repositioned by retrieval device after a difficult filter release, as the hook was against the wall.A single poor quality image submitted for review demonstrates a celect platinum ivc filter with 16° rightward tilt resulting in the hook abutting the right lateral wall of the ivc.The complaint report states "filter would not release properly".There was no elaboration or description of what was meant by this statement.The ifu for the celect platinum ivc filter states slight back tension needs to be applied to the filter when pressing the release mechanism to allow the filter hook to detach from the deployment mechanism.If excessive back tension is applied, the filter will not release from the detachment hook.If this scenario was encountered, while attempting to release the filter, the physician tried to push the entire device caudally, in attempts to disengage the hook, this action could have resulted in the filter tilt.Unfortunately, without further information regarding the actual difficulties encountered when deploying the ivc filter, this is only speculation.The complaint report also states "the retrieval device used to reposition the ivc filter" suggests the deploying physician retrieved the ivc filter or at least repositioned it in such a way that the filter no longer exhibited a significant tilt.There are no images confirming this statement.There are adequate controls in place to ensure the device was manufactured to specifications.The device history record was reviewed with no evidence to suggest that the device was not manufactured according to specifications.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.
