Manufacturer Narrative

Device evaluated by mfr.: the stent delivery system was returned for analysis.A microscopic examination of the stent struts found no evidence of foreign matter.It was noted that the stent was damaged.The struts from the centre of the stent were severely distorted and were stretched distally towards the tip of the device.The stent length was measured with a calibrated ruler to be 55mm.This type of damage is consistent with the stent encountering resistance possibly during the preparation of the device.The balloon and tip sections of the device were visually and microscopically examined and no issues were noted with their profiles that could have potentially contributed to the complaint incident.The balloon was tightly wrapped and was not subjected to positive pressure.The hypotube was kinked at various locations along its length.This type of damage is consistent with excessive force being applied to the delivery system possibly during packaging for return.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 most probable root cause is considered handling damage as the event occurred without direct patient contact.(b)(4).
