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 devices shaft showed one kink located 126.5cm from the tip.The tip showed a bend.The occ handle was connected to the ffr link to verify the signal strength.The signal was present as designed.The sensor port showed no residue of body fluids.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 was confirmed to be in specification.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.The wire was inserted into the test pressure chamber and the wire transferred a pressure waveform to the polaris which indicated a functioning wire.The wire was removed from the occ handle with no issues.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.Because there was no evidence of any product quality deficiencies, it was considered likely that the kink and tip damage were attributable to handling issues.
