H11: manufacturing review: the device history records have been reviewed, and this lot met all release criteria.Investigation summary: one denali femoral filter kits were received for evaluation.The kit included one pusher catheter, touhy borst adapter loaded onto a filter storage tube and an introducer sheath loaded onto the distal end of the filter storage tube and a dilator.The filter was not returned.Upon visual inspection the complaint sample appeared to have blood residue throughout.The distal end of the sheath was observed to be cut, and the distal segment was not returned.The distal tip of the dilator was observed to be deformed.The pusher catheter was noted to be pushed within the loaded devices.Functional testing an attempt to advance loaded pusher catheter throughout the loaded devices (touhy-borst adapter, filter storage tube and introducer sheath) was performed and small resistance was felt.Filter was noted within the introducer sheath.The attempt was successful when the filter deployed from the distal end of the introducer sheath.Filter limbs were present, and no legs were noted to be crossed.What appeared to be blood tissue, was noted throughout the filter legs.The pusher catheter was offloaded from the touhy-borst adapter, filter storage tube and introducer sheath without issue.No anomalies were noted to the pusher wire.The touhy-borst adapter and the filter storage tube was offloaded from the introducer sheath for further evaluation.The touhy-borst adapter was offloaded from the filter storage tube.Slight skiving was noted throughout the filter storage tube.The distal catheter segment was not returned.Therefore, the investigation is inconclusive for the reported positioning failure as the conditions during use cannot be recreated.Investigation is identified and confirmed for the deformation due to compressive stress as the distal tip of the dilator was noted to be deformed.Investigation is identified and confirmed for the detachment as the distal end of the sheath was observed to be cut.A definitive root cause for the reported positioning failure and identified deformation due to compressive stress and detachment could not be determined based upon the provided information.Labeling review: as the reported event did not allege a labeling or use related issue, a labeling review is not required.Section a through f: the information provided by bd represents all the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
