Manufacturer Narrative

Device evaluated by mfr: a visual and microscopic examination was performed on the returned device which revealed a section of one of the blades, approximately 3mm in length was partially detached from the proximal end of the balloon material and lifted distally.The remaining section of blade measuring approximately7mm in length was undamaged and fully bonded to the balloon material.The entire 10mm of blade was accounted for.The entire blade pad remained fully bonded to the balloon material.The damage identified can potentially be a result of the resistance encountered during the withdrawal of the device.All other blades were intact and fully bonded to the balloon material.No issues were noted with the blades or pads that could have contributed to the complaint incident.A visual and microscopic examination of the balloon noted that the balloon was unfolded and had been subjected to positive pressure.A balloon longitudinal tear was identified beginning approximately 4mm distal to the distal edge of the distal markerband and extending approximately 8mm proximally across the balloon material.An examination of the balloon material and distal markerband identified no issues which could potentially have contributed to this complaint issues were noted with the balloon material that could have contributed to the complaint incident.No issue was observed with the tip or markerbands of the device which could have contributed to the complaint incident.A visual and tactile examination identified no kinks or issues along the length of the device.No other issues were identified during the product analysis.
