(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.(b)(4).The device was not returned for analysis.A review of the lot history record and complaint history of the reported lot could not be conducted, because the lot number was not provided.The reported failure to cross and stent dislodgement appear to be related to interaction with the patient calcification.It should be noted that the rx herculink elite renal and biliary stent system instructions for use states: the rx herculink elite renal stent system is indicated for use in patients with atherosclerotic disease of the renal arteries.Additionally, the warning section states that applying excessive force to the stent delivery system can potentially result in loss or damage to the stent and delivery system components.The use of force was likely applied due to case circumstances related to heavy calcification.Based on the information reviewed, there is no indication of a product quality issue with respect to manufacture, design or labeling of the device.
