The device history records were reviewed with special attention to the raw materials, subassemblies, manufacturing process and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.The device was returned severly damaged with bunching of the outer catheter and guidewire lumen.The outer catheter was torn near the rapid exchange junction and the guidewire was found bent.The guidewire and inner guidewire lumen were protruding out the distal tip of the catheter.After the catheter was straightened out, the guidewire was removed with resistance.The guidewire and inner guidewire lumen of the recanalization catheter were examined under a microscope and no signs of melting were observed.The investigation is inconclusive as functional testing could not be performed due to poor sample condition.Per the related details, the same user experienced 15 events over a short time period where the guidewire and catheters melted during use, therefore, the user's flowmate injector and generator were replaced and the user has not experienced the issue since.It is likely that the injector and/or generator contributed to the reported event, however, based upon the available information the definitive root cause is unk.
