(b)(4).Internal file number - (b)(4): during processing of this complaint, attempts were made to obtain complete event, patient and device information.Date of event: estimated.In the absence of a reported part number, the udi cannot be calculated.Implant date: estimated.The device was not returned for evaluation.A review of the lot history record and complaint history of the reported devices could not be conducted because the part and lot numbers were not provided.The reported patient effects of myocardial infarction and thrombosis, as listed in the bioresorbable vascular scaffold (bvs) system, absorb, instructions for use are known adverse events associated with the use of a coronary scaffold in native coronary arteries.The investigation was unable to determine a conclusive cause for the reported scaffold malposition and patient effects.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.The absorb device is currently not commercially available in the u.S; however, it is similar to a device sold in the u.S.Literature attachment: an observational study of clinical outcomes of everolimus-eluting bioresorbable scaffolds comparing the procedural use of optical coherence tomography against angiography alone.
