Pma/510(k)#: p100022/s001.The ziv6-35-125-6-80-ptx device of unknown lot number was implanted in the patient and is therefore unavailable for evaluation.With the information provided a document based investigation was carried out.According to information provided, the stent was implanted 2 days past the expiry date.Additional information was requested but no information has been received to date.There is no evidence to suggest that this event did not occur, therefore the complaint is confirmed based on customer testimony.All zilver ptx devices are shipped with a product label placed on the outer zilver ptx carton box and product label placed on the inner pouch.Both labels contain information with manufacturing and expiration dates.In addition, the following is stated in the instructions for use provided with each ptx device: ¿do not use the stent after the ¿use by¿ date specified on the package¿.Based on the above, the most likely cause of this complaint can be attributed to customer error as zilver ptx devices should not be used beyond the date specified on the product label.As the lot number of the complaint device is unknown, a review of the relevant documentation cannot be conducted.However, prior to distribution all zilver ptx devices are subject to visual inspection and functional checks to ensure device integrity.In addition, 100% inspection is carried out on all labels.No adverse effects have been reported for this patient.Quality engineering will continue to monitor complaints of this nature for potential emerging trends.
