Manufacturer Narrative

Combination product: yes the complaint instrument was not returned for a technical investigation.Therefore, no technical investigation on the subject could be performed.The corresponding production documentation was reviewed to establish whether a deviation from the manufacturing process could be the cause for this event.In addition, the angiographic material provided was reviewed.Review of the production documentation for the product detailed above verified that the instrument was manufactured according to specifications and fulfilled all the requirements of in-process and final inspection.During final inspection, every stent system undergoes visual inspection to ensure correct stent embedding and homogeneous crimping of the stent.Further, the stent outer diameter is verified to 100 percent and the stent retention force of a defined amount of samples is tested from every lot.Review of the angiographic material showed the dislodged complaint stent which is entangled with its distal end at the proximal end of a previously implanted stent over the bifurcation towards the target lesion.The actual complaint event has not been recorded.Based on the conducted investigations of the device being subject to this complaint, no material or manufacturing related root cause could be determined.The root cause for the reported complaint event is therefore most likely related to the patients anatomy (previously implanted stent).
