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 post filter deployment, computed tomography angiogram (cta) revealed that partially occlusive eccentric pulmonary embolism was visualized extended from the distal portion of the right main pulmonary artery and into the right lower lobe branch.
The basal branches were sub optimally opacified and therefore difficult to accurately access.
There was no pleural or pericardial effusion.
Lung windows demonstrated 2 separate, 5 mm nodules in the right middle lobe.
Approximately sixteen days later, computed tomography (ct) revealed that an infrarenal inferior vena cava filter was stable in position and appearance.
However, no device deficiencies were identified in the provided medical record.
Therefore, the investigation is inconclusive as no objective evidence has been provided to confirm any alleged deficiency with the filter.
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.
