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.After one month and six days of post filter deployment, computed tomography (ct) scanning was revealed that inflammation and blood along the right side of the inferior vena cava filter which was placed over l2, had migrated down to l4 with a couple of the legs outside the vena cava with some retroperitoneal bleeding.Subsequent impression from ct was revealed the tilt of the filter and two or three of the tines were outside of the inferior vena cava.One day later, on 12-apr-2010 an retrieval attempt was made with the right internal jugular vein with bard retrievable device, but it was not successful the retrieval was very difficult.An second attempt made with variety of sizes of gooseneck snares and an ensnare but still not able to retrieve the filter.The filter appeared to be embedded in the wall.The left common femoral vein was cannulated, the filter was retrieved entirely.Therefore, the investigation is confirmed for perforation of the ivc, filter migration, filter tilt and retrieval difficulties.However, the investigation is inconclusive for filter limb detachment.Per medical records, multiple attempts were made to engage the filter using snare but were unsuccessful due to filter tilt and embedment.This could have contributed to the retrieval difficulties.However, the definitive root cause is unknown.Labeling review: instructions for use: warnings: the safety and effectiveness of this device has not been established for morbidly obese patients.Open abdominal procedures such as bariatric surgery may affect the integrity and stability of the filter 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.
