Device evaluation: the complaint was confirmed as the inability to load was due to the broken endoanchor found within the tip of the applier.The exact cause of the broken endoanchor cannot be conclusively determined.Based on historical analysis of similar broken endoanchor complaints, there is no evidence of a material defect that would have been contributory.Conditions during the procedure that have historically been identified as causes of deployment resistance include difficulty positioning the heli-fx applier within highly angulated anatomy as well as calcified plaque or thrombus with more than 2mm of thickness within the deployment zone.In addition, encountering a stent strut may have also contributed to the event.

Heli-fx endosystem was prophylactically used during an endovascular procedure.The heli-fx endosystem was used with a medtronic stent graft.There was no calcification present.It was reported that during the index procedure, the physician was able to implant three endoanchors, but while loading the fourth one, the applier stopped working.The fourth endoanchor was loaded with half of it sticking outside of the applier d-drive.The physician attempted to reload the endoanchor but was still seeing the same issue.As a result, the physician used another applier and the procedure was successfully completed.Per the physician, the cause of the event was related to the device.No clinical sequelae were reported and the patient is fine.
