Event or Problem Description
An orsiro mission drug-eluting stent system was selected for treatment of a moderately calcified lesion (stenosis degree: 80 percent) in the mildly tortuous proximal l peroneal.The lesion could not be crossed with the device.The stent was removed, and it was noted that the stent was bent on the delivery system and was unable to be re-inserted.
Additional Manufacturer Narrative
Combination product: yes.The returned product was subjected to a technical analysis and the corresponding production documentation was reviewed to establish whether a deviation from the manufacturing process could be the cause for the reported event.The technical investigation of the returned device revealed that the stent is deformed at its proximal end.Several stent struts are bent outwards.Microscopic analysis revealed stent imprints on the exposed balloon surface, indicating that the bent struts were initially crimped on the balloon.Outside of the deformed zone the crimped diameter of the stent complies with the specification.Review of the production documentation confirmed that the product was manufactured according to specifications and passed all in-process and final inspections.During final inspection, every stent system undergoes visual inspection to ensure correct stent embedding and homogeneous crimping of the stent.Based on the conducted investigations of the device being subject to this complaint, no material or manufacturing related root cause could be determined.It should be noted that the ifu states that the orsiro mission is indicated for improving coronary luminal diameter in the native coronary arteries.
