Manufacturers ref# (b)(4).Summary of investigational findings: the filter would not detach after pressing the blue button to release.When it did detach, the placement was not acceptable, so the physician used a retrieval set to reposition.No patient harm and no further action needed.Three images from the time of ivc placement were provided for clinical assessment.Per clinical assessment, first image demonstrates an inferior venacavogram performed via a jugular approach with a flush catheter positioned at the confluence of the iliac veins.There is no scale to determine the exact diameter of the ivc but using the spine hardware as a frame of reference, the infra-renal ivc measures ~13mm.The infrarenal ivc does appear small in caliber supporting this calculation.Per clinical impression, the 2 fluoroscopic images demonstrate a celect platinum ivc filter in the infrarenal ivc without evidence of significant tilt or any other issue.It is presumed this is the final position of the ivc filter after repositioning the filter.A curved jugular introducer with protection sheath was provided for product evaluation.Blood/biological matter was present.Because of the blood/biological matter it has no release function.Therefore, it has to be soaked and then after it was possible to attach and release a filter.Per the product evaluation, the likely cause is that excessive tension during deployment may prevent the filter from releasing when the release mechanism is activated.Review of device history record showed no evidence to suggest that the device was not manufactured according to specification.According to instruction for use excessive tension during deployment may prevent the filter from releasing when the release mechanism is activated.Based on the provided information, clinical assessment and product evaluation a likely cause is that tension during deployment prevented the filter from being released.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.
