Manufacturer Narrative

Device evaluated by mfr: the delivery system was returned with the stent deployed.The deployed stent was not returned for analysis.A visual and tactile examination identified a severe shaft kinking and stretching damage along the length of the device.The majority of the damage was noted approximately 1260mm distal to the strain relief.Both the inner shaft and outer sheath were severely kinked and stretched.The outer sheath was also noted to be fully retracted and could not be repositioned over the inner shaft during analysis due to the severe shaft damage.The damage identified is consistent with excessive force being applied to the delivery system.No issues were noted with the catheter that could have contributed to the damage identified.A visual and microscopic examination was performed on the stent holder, stent cups and markerbands of the device.No damage or any issues were noted that could have contributed to the complaint incident.A visual and microscopic examination identified that the tip of the device was damaged.A section of the tip approximately 2mm in length was noted to be completely detached from the device.This detached section of tip was not returned for analysis.No other issues were identified during the product analysis.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The investigation conclusion was unable to be determined.(b)(4).
