It was reported that the stent was prematurely deployed when advancing onto the guidewire.An eluvia eu, 7x60, 130 cm was selected for use in the superficial femoral artery (sfa) to treat the patient's stenosis.During device preparation, the eluvia delivery system was attempted to be advanced over the amplatz super stiff guidewire 0.035 in, but resistance was encountered.To facilitate advancement, the physician pushed the catheter from the tip, which resulted in a partial stent deployment outside of the patient.Additionally, a polymer-like material was noted on the table, which was suspected to be from the eluvia.Of note, no foreign matter was noted on the eluvia or in the device packaging.The eluvia and amplatz were both replaced in order to complete the procedure.The procedure was completed and there were no adverse consequences reported for the patient.
