As reported, the palmaz genesis 6.0 x 15 stent mounted on a 142 cm.Rx amiia stent delivery system (sds) was delivered to the lesion but its distal stent edge got frayed.It was removed from the patient and there was no reported patient injury.It is unknown how the procedure was completed.The target lesion was the renal artery and was reported to be: heavily calcified and heavily tortuous and rate of stenosis was (b)(4).The product was clinically used and it will not be returned for analysis.Additional information has been received.The procedure was completed successfully.There is no reported information to explain how the procedure was completed or with what devices.The product was stored and handled according to the instructions for use (ifu).The product was inspected and prepped according to the instructions for use.There was nothing unusual noted about the device prior to use.The following information was reported as unknown: if there was any stent strut uplift noted; if it appeared to have moved on the delivery system; if there was any other product issue noted either at the account or after the procedure; if the device passed through any acute bends; if any difficulty was encountered while advancing/tracking the device towards the lesion; if there was any unusual force used at any time during the procedure; or if there was thrombus present prior to, at, or after the lesion site.
