Dhr (device history records) review (dated may 10, 2020) indicated that the product was supplied meeting specifications.Ifu (instructions for use) review (dated may 27, 2020) indicated that no deviation of ifu was reported.Based on medinol's interventional cardiologist opinion the stent which occluded the tiny branch and narrowed the second larger branch almost certainly was the cause or a contributory cause of the mi.Based on this assumption, the event was related to the device described in this mdr and not to the device detailed in mdr number 3003084171-2020-00003.Final report overall conclusions (dated may 27, 2020): 1.The review of the dhr (device history record) indicates that the product was supplied meeting specifications.2.Myocardial infarction is a well-known potential adverse event that may be associated with the implantation of a coronary stent in coronary arteries and is listed as such in section 8 of the elunir ifu.3.In the opinion of medinol's interventional cardiologist, the occlusion of a tiny branch and narrowing of a second larger branch during implantation of the stent was almost certainly the cause or a contributory cause of the mi.4.The events of this complaint are addressed in the elunir dmfea report and their risks remain low.No new risks were identified.5.The patient recovered.
