Manufacturer Narrative

Combination product: yes the returned product was subjected to a detailed technical analysis and the corresponding product release documentation was reviewed to establish whether a deviation from the manufacturing process could be the cause for this event.The technical investigation revealed that the hypotube has fractured at the distal end of the kink protector.The cross-section of the hypotube at the fracture sites is no longer circular but compressed into an ellipse.The polymer coating is plastically deformed.The hypotube is also strongly kinked about 171 mm distal to the fracture site.The findings indicate that the hypotube most probably fractured as a result of significant bending outside of the patients body.In addition, the stent was found mildly deformed in its center (i.E.Few struts are slightly bent outwards).The crimped diameter of the stent does not comply anymore with the specification.Review of the product release documentation confirmed that the instrument was manufactured according to specifications and passed all in-process and final inspections.Based on the conducted investigations of the device being subject to this complaint, no manufacturing or material related root cause could be determined.The root cause for the complaint event is most likely related to the handling during the preparations for the intervention.
