Age of time of event: 18yrs below.Device evaluated by mfr.: returned product consisted of a zelantedvt thrombectomy system.The pump assembly, effluent/supply line, shaft, hypotube, tip, and spike line were visually inspected.Blood was present inside the device and the waste bag was cut-off and not returned for analysis.Inspection of the device revealed that the hypotube was twisted from the hub distally to the proximal markerband.Functional testing was started but the 'onnect saline supply' error was displayed on the console and the device would not prime with fluid filling the boot.The proximal markerband and shaft were cut-off to examine the proximal saddle.There was no damage to the saddle, as it was still intact and attached to the hypotube.But with shaft cut, the hypotube moved and it was revealed through microscopic examination that the hypotube was detached at the jet body.The separated ends of the hypotube appeared to be ovaled, indicating that the hypotube was compressed before separation.It was most likely that the shaft was turned around consistently causing the hypotube to be twisted and eventually break due to the force at the jet body, when the hypotube is separated, the device will not prime and the console will continue to try and prime the catheter, causing the 'connect or check saline supply' error to display on the console and the boot to fill with fluid.

Reportable based on device analysis completed on 29-july-2020.It was reported that an error message occurred.An angiojet zelantedvt catheter was used for a thrombectomy procedure.During the procedure, the device was used for 300 seconds and then system prompted check saline supply error.The procedure was completed with another of the same device.No patient complications were reported and patient's status was stable.However, device analysis revealed a hypotube break.
