H10: manufacturing review: a manufacturing review was not requested as the lot number reported is unknown.Investigation summary: the device was not returned for evaluation.Medical records were provided and reviewed.A new meridian filter was placed, released, and centered around l3.The filter did not completely release initially.This seemed to be related to likely previous thrombus in the vena cava, which had resolved.The balloon was then used to test the filter and as it was pulled proximally, the filter was engaged well in the wall and would not move.Approximately, two years six months of post deployment, computed tomography of abdomen and pelvis with contrast demonstrated an infrarenal inferior vena cava filter which was predominantly collapsed and there was no significant caval lumen.It also demonstrated an occluded inferior vena cava.After, twenty-six days, inferior venacavogram demonstrated an inferior vena cava occlusion started approximately 1 cm above the inferior vena cava filter which was fibrosed down.After, twenty-one days, it was found to have occlusion of common femoral veins to inferior vena cava with shrunken and scarred inferior vena cava filter.Around, eleven months and twenty-two days later inferior venacavogram showed that an inferior vena cava filter was in position below the left renal vein.Around, one year nine months later, inferior venacavogram showed an inferior vena cava occlusion with a shrunken inferior vena cava filter identified.Therefore, the investigation is confirmed for the material deformation, positioning problem and occlusion of the inferior vena cava (ivc).The definitive root cause could not be determined based upon available information.Labeling review: a review of product labeling documentation (e.G., procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.H10: b6, g3, h6 (method).H11: h6 (result and conclusion).H11: section a through f ¿ the information provide 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.
