Event or Problem Description
An orsiro drug-eluting stent system was chosen to treat a pre-dilated severely calcified lesion (70 percent stenosis degree) in a severely tortuous distal cx.While trying to cross an previously implanted stent, the orsiro stent dislodged proximal to the lesion.The stent was attached inside the previous stent.
Additional Manufacturer Narrative
Neither the complaint instrument nor the angiographic material was provided for analysis.Therefore no technical investigation on the subject could be performed.The production documentation was reviewed to establish whether a deviation from the manufacturing process could be the cause for the reported event.Review of the production documentation of the product detailed above did not reveal any non-conformity.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.The device in question was manufactured according to specifications and successfully passed all inprocess controls as well as the final inspection.Based on the conducted investigations no manufacturing related root cause was determined.The root cause is most likely related to the previously implanted stent.
