The event was reassessed as an mdr following the device analysis report (dated nov.28, 2019), the event classification was updated from: "tracking difficulty over guidewire" to "tracking difficulty over guidewire, damaged spring tip - in patient, stent strut uplift- in patient".Ifu review was conducted and indicated that no deviation of ifu were reported.Overall conclusions from the final report (dated dec.02, 2019): the review of the dhr (device history record), along with the information from the customer and the device analysis report indicate that the product was supplied meeting specifications.According to the device analysis report, the customer complaint was confirmed.It seems that a kink on the guidewire caused the system to lock on the guide wire at the distal fuse.Excessive forces exerted on the system, evidently in attempts to free it from the guidewire, resulted in stent deformation, tip extension and other anomalies.There was no injury to patient.
