Additional Manufacturer Narrative
(b)(6).Device evaluated by mfr: the returned product consisted of an ffr comet pressure wire connected to the occ cable.The tip, device shaft and sensor port were examined for damage or any irregularities.The wire shaft showed kinks located 43cm and 53cm from the tip.There was peeled coating at these locations.The occ cable was connected to the ffr link for signal verification.The signal was not present as designed.Device analysis was conducted by inspecting the proximal end of the wire for any damage to the fiber optic.No damage was noticed.The sensor was inspected by viewing the sensor port to verify that the sensor was in the correct location.This sensor looked to be too far distal which would give the indication of the sensor being detached from the fiber optic cable.The wire was gently shaken to see if the sensor would move within the sensor housing and the sensor did move which verifies the sensor was detached from the fiber optic.The coefficient values were confirmed to be programmed.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.Device analysis determined the condition of the returned device was consistent with the reported information of a pressure signal issue.The reported complaint of a pressure issue was confirmed.
Event or Problem Description
It was reported that signal issues occurred.During insertion of a comet pressure guidewire, a loss of signal occurred.It was noted that no pressure was displayed during insertion.The procedure was completed with another of the same device.No patient complications were reported in relation to this event.However, device returned and device analysis revealed peeled coating.
