Additional Manufacturer Narrative
The tip, device shaft, sensor port and the coefficient values were examined for damage or any irregularities.The wire showed 2 kinks located at 128.5cm from the tip and at the occ handle.Peeled coating was noticed at the 128.5cm location.The tip showed tip damage.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.The device was confirmed for tip and shaft damage.
Event or Problem Description
Reportable based on device analysis completed on 23 jun 2020.It was reported that the was difficulty crossing the lesion and the tip became damaged.It was reported that this comet gen 1 pressure guidewire was selected for a percutaneous coronary intervention.The 75% stenosed target lesion was located in the moderately tortuous vessel and severely calcification right coronary artery.The lesion was predilated with an emerge balloon catheter.While advancing the comet pressure wire the physician could not pass through the angle due to the resistance.Upon removal tip damage was noticed.The procedure was completed with another of same device.No patient complications were reported and the patient status was stable.Device analysis revealed peeled coating.
