Device evaluated by manufacturer: returned product consisted of a solent dista thrombectomy.Visual inspection of the device revealed numerous kinks throughout the shaft of the catheter.Functional testing was performed by placing the device in the angiojet console.The device failed to prime and the check catheter for kinks error was displayed on the screen, meaning that the device over-pressured.The shaft was inspected again by cutting the shaft at some of the more severe kinks but the hypotube had no damage and there was no reason that would have caused an over-pressure alarm.The device was removed from the console and the shaft was inspected again.The tip was cut and the jets were microscopically inspected and it showed that there was dried saline and blood so the device was sonic cleaned for 30 minutes to clear the jet holes.After sonic cleaning the device was ran again and once again over-pressured, so the jets were checked again and it was revealed that a jet hole was plugged, causing the over pressure as the flow was being restricted.Further analysis revealed the obstructed jet hole was plugged with gold, which the jet body material is made of.Inspection of the remainder of the device revealed no damage or other irregularities.
