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 four years post filter deployment, patient presented with chest pain.Subsequent ct revealed that there was thrombus in the sub segmental branches of the left lower lobe, right lower lobe, suggesting acute bilateral pulmonary embolism.Approximately two and half years later, ct revealed ivc filter appeared to be slightly upwardly positioned and the tip appeared to be at the level of left renal vein.There was slight tilting of the filter noted as well.One of the filter legs appear to be outside the vena cava with no evidence of localized hematoma.Therefore, the investigation is inconclusive for filter migration, filter limb detachment, perforation of the ivc and filter tilt.Based on the provided medical records, there is no clear evidence to confirm for perforation of the ivc as it reported that, ¿one of the filter legs appear to be outside the vena cava¿.Based on the provided medical records, there is no clear evidence to confirm for filter tilt as it reported that, ¿there was slight tilting of the filter noted as well.¿ additionally, it can be confirmed that the patient experienced pe post deployment.However, the relationship to the filter is unknown.Based upon 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.(expiry date: 06/2014), (b)(4).

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 four years post filter deployment, patient presented with chest pain and acute bilateral pulmonary embolism.Subsequent ct revealed that there was thrombus in the sub segmental branches of the left lower lobe, right lower lobe, suggesting acute bilateral pulmonary embolism.Approximately two and half years later, ct revealed inferior vena cava (ivc) filter appeared to be slightly upwardly positioned and the tip appeared to be at the level of left renal vein.There was slight tilting of the filter noted as well.One of the filter legs appear to be outside the vena cava with no evidence of localized hematoma.Eventually three months later, filter retrieval was scheduled.Subsequent inferior vena cavogram revealed, inferior vena cava filter was tilted, and apex of the filter was near the left renal vein origin.Multiple attempts were then made to snare the hook with help of straight, angled and trilobed snare but filter was embedded in the wall.Multiple attempts were made unsuccessfully.Therefore, the investigation is confirmed for the filter tilt and retrieval difficulties.However, the investigation is inconclusive for filter migration, filter limb detachment and perforation of the ivc.Based on the provided medical records, there is no clear evidence to confirm for perforation of the ivc as it reported that, ¿one of the filter legs appear to be outside the vena cava¿.Additionally, it can be confirmed that the patient experienced pulmonary embolism (pe) post deployment.However, the relationship to the filter is unknown.Per medical records, multiple attempts were made to engage the hook of the filter using straight, angled and trilobed 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: 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: b7,d11,d4(expiry date: 06/2014),.
