H10: manufacturing review: a manufacturing review was not requested as the reported lot number is unknown.Investigation summary: the device was not returned for evaluation.Medical records were provided and reviewed.During deployment, repeat angiography demonstrated the filter was not satisfactory position.In fact, it was located in the sidewall of the inferior vena cava and did not open well, tried then to retrieve and reposition from the jugular vein approach.Jugular access was gained and passed a wire into distal inferior vena cava.A snare was deployed; it was not in the same plane as the filter and unable to retrieve the filter.Examination with fluoroscopy has been done, and do not believe that it was harmful, so we chose to leave it in place.I did not want to place another due to the difficulties and unlikelihood that we would attempt further procedures on the left leg.Therefore, the investigation is confirmed for the reported positioning failure, activation failure during expansion and difficult to remove.Based upon the available information, the definitive root cause is unknown.Labeling review: as the reported event did not allege a labeling or use related issue, a labeling review is not required.H11: 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.H3 other text : device not returned.
