(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.There was no reported device malfunction and the product was not returned.The lot history record (lhr) for this product could not be reviewed because the product was not returned for evaluation and the lot number was not reported.The reported patient effects of neurological deficit/dysfunction, weakness, transient ischemic attack (tia), cerebrovascular accident (cva), and thrombosis are known potential patient effects as listed in the xact carotid stent system instructions for use (ifu).Based on the information reviewed, there is no evidence to indicate the presence of a product deficiency.
