Manufacturer Narrative

Device evaluated by mfr.: stent delivery system was returned for analysis.A visual examination of the stent found no issues on the stent.There were no signs of damage, stretching or lifting of the stent struts.The stent showed no signs of movement and was set equidistant between the proximal and distal markerbands.The crimped stent od (outer diameter) was measured and the result was within the maximum crimped stent profile measurement.A visual examination of the bumper tip showed no signs of damage.The balloon cones were reviewed and no issues were noted.The balloon wings were tightly wrapped and evenly folded and were not subjected to positive pressure.A visual and tactile examination found multiple kinks along several locations of the hypotube shaft.This type of damage noted most likely occurred due to excessive forces that could have been applied on the delivery system.A visual and tactile examination of the inner and outer lumen and mid-shaft section found no issues with the extrusion shaft.The bicomponent bond showed no signs of damage or strain.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 is not confirmed - returned as there was no evidence of either the alleged issue(s) or any defect which could have contributed to the event.(b)(4).
