It was reported that the procedure was to treat a lesion located in the superficial femoral artery.The vessel reference diameter was measured to be 6.0; therefore, a 6.5 supera stent was used.Pre-dilatation was performed with a 7 mm balloon catheter and the vessel was appropriately sized prior to deployment of the supera stent.After successful deployment of the supera stent in the vessel, during retraction of the device from the anatomy, the tip of the catheter became caught on the edge of the deployed stent.The tip separated from the catheter inside the patient and attempts to retrieve the tip were unsuccessful; therefore, the tip was stented against the vessel wall.The patient outcome was good.There was a two plus hour delay in the procedure due to the device issue.No additional information was provided.
