H10: manufacturing review: the device history records have been reviewed with special attention to the raw materials, subassemblies, manufacturing process, and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Investigation summary: the device was not returned for evaluation.Medical records were provided and reviewed.Approximately twelve years and seven months of post deployment, a computed tomography of abdomen and pelvis was performed for abdominal pain.The study showed that inferior vena cava filter was positioned below the level of renal veins.Some of the filter struts have penetrated through the wall of the inferior vena cava into the mesenteric fat.One of the arms penetrates into the aorta.A filter arm on the left side was fractured and was outside of the inferior vena cava lying adjacent to the aorta with its long axis parallel to the inferior vena cava.No filter tilt and migration were noted.Therefore, the investigation is confirmed for perforation of the inferior vena cava (ivc) and filter limb detachment.Based on the available information, the definitive root cause is unknown.Labeling review: a review of product labeling documents (e.G.Procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, and unit label) showed that the product labeling is adequate.H10: d4 (expiry date: 01/2008), g3, h6 (method).H11: h6 (result and conclusion).H11: section a through f - the information provided by bd represents all of 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.
