Additional Manufacturer Narrative
(b)(6).Returned product consisted of an ffr comet pressure wire connected to the occ handle.The tip, device shaft, sensor port and the coefficient values were examined for damage or any irregularities.The wire showed a kink located 147.5cm from the tip.There was also peeled coating at this location.The occ handle was connected to the ffr link to verify the signal strength.The signal was present and showed green lights as designed.The occ handle was then connected to the bench top testing equipment and the wire was inserted into the pressure chamber.The pressure was increased to verify the sensor was indeed reacting to the pressure increases and decreases.The pressure sensor functioned as designed.The coefficient values were confirmed to be programmed.The occ handle was again connected to the ffr link.The device was then connected to the polaris (ilab) test equipment via bluetooth signal.The wire communicated to the polaris system and zeroed as designed.With the wire inserted into the test pressure chamber, the wire transferred a pressure waveform to the polaris which indicates a functioning wire.The wire was removed from the occ handle with no issues.The sensor port showed no residue of body fluids.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.
Event or Problem Description
Reportable based on analysis completed on 12may2020.A percutaneous coronary intervention was being performed on a 90% stenosed, moderately calcified and moderately tortuous lesion.The comet pressure guidewire was advanced but could not cross the lesion.The procedure was successfully completed with a different device without issue or patient injury.However, returned device analysis revealed peeled coating.
