This device is used for treatment not diagnosis.The ventricular assist system is indicated for use as a bridge to cardiac transplantation and destination therapy in patients who are at risk of death from refractory end-stage left ventricular heart failure.The system is designed for in-hospital and out-of-hospital settings.Product event summary:a controller with unknown serial number was not returned for evaluation.The reported event could not be confirmed as the device was not returned for analysis.Applicable risk documentation and experience with events of similar circumstances were considered; a possible root cause of loose power port connectors may be attributed to inadequate thread lock, an inconsistent thread lock cure time and an inadequate torque application during the assembly process.This event was reported in the intermacs data registry that tracks clinical outcomes of patients on ventricular assist device (vad) support.The data registry does not contain device identifying information or event date and therefore cannot be correlated to any previously received report of the event.Based on the provided data, device analysis will not be possible and no further information will likely be made available concerning the event.If information is provided in the future, a supplemental report will be issued.
