It was reported that the procedure was to treat an 80% stenosed lesion distal to a previously deployed supera stent in the superficial femoral artery (sfa).Pre-dilatation was performed with a 5.0x40mm unspecified balloon dilatation catheter (bdc) for two minutes.The 4.5mmx40mmx120cm supera self-expanding stent system (sess) was successfully advanced to the target lesion and the stent was deployed.However, during withdrawal of the delivery catheter, resistance was met and the tip separated.When the delivery catheter was removed, it was noted that the stent elongated and was explanted from the patient's anatomy.The separated tip was successfully retrieved using a snare device.Due to the clinically significant delay in the procedure, the decision was made to stop the procedure at that time.Future treatment of the vessel is planned; however, an exact date for the planned treatment is not known.There was no reported adverse patient sequela.There was no additional information provided.
