Device is a combination product.Device returned to manufacturer: the agent drug-coated balloon was received and analysis was completed.The outer shaft, inner shaft, balloon and tip were visually and microscopically examined.Visual examination revealed that the tip was separated and did not return for analysis.The location of separation appears to have been stretched.Microscopic examination revealed buckling to the guidewire lumen approximately 17mm from the separation and is approximately 9mm long.The balloon is deformed at the buckling section.The guidewire lumen is stretched 64mm from the separation.There is a hole in the guidewire lumen 65mm from the separation and it appears to have been made by a guidewire puncturing it.Product analysis confirmed that the damage found to the device would have caused difficulty to load or track a wire.
