An orsiro drug-eluting stent system was chosen for treatment of a severely calcified lesion (80 percent stenosis degree) in a tortuous lad.During attempt to cross a previous implanted stent resistance was felt.Upon removal it was noticed that the stent dislodged from the system.The stent was retrieved with a snare.
Additional Manufacturer Narrative
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 this event.The technical investigation of the returned delivery system revealed that the balloon is still folded and does not show any signs of inflation.Microscopic analysis of the balloon surface revealed clear visible stent imprints, indicating that the stent was properly crimped in between the two radiopaque markers at the time of delivery.The stent was returned separately and severely deformed at both ends.Review of the manufacturing history 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 be 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 of the device being subject to this complaint, no material or manufacturing related root cause was determined.
