An euphora balloon was attempted to be inserted over the fractional flow reserve (ffr) wire with inability to advance the balloon.When provider pulled back on ffr wire, he noted fraying of the wire.This portion of the wire was external to the patient.But the provider did not continue use of the wire due to the fray.Provider used a different wire and procedure was completed without issue.There was not patient harm to that occurred.Manufacturer response for pressure wire, pressure wire aeris agile tip (per site reporter).The st.Jude representative replaced our lot and that he would follow up with his reporting process.
