Manufacturer Narrative

Device evaluated by mfr: the product was returned to boston scientific for analysis.Returned product consisted of an ffr comet pressure wire connected to the occ cable.The tip, device shaft, sensor port and the coefficient values were examined for damage or any irregularities.The wire showed 1 kink located 163.5cm from the tip.The tip showed bend damage.There was evidence of peeled coating at the 163.5cm 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.The complaint was not confirmed for signal/equalizing issues.

Event Description

It was reported that a comet wire could not equalize.During preparation and while outside the patient, a comet pressure guidewire could not be equalized with a polaris cart.It was noted that no sedation was given.The device was removed to complete the procedure.No patient complications were reported in relation to this event and the patient was reported to be stable following the procedure.However, device analysis revealed peeled coating.
