[Methodological Study of Reliability Test of Percutaneous Ventricular Assist Device].

Prior to clinical application, reliability of percutaneous ventricular assist devices(pVAD) requires to be tested systematically. Currently, there's a lack of dedicated reliability testing equipment and methodologies for pVAD. Considering the structural and functional aspects of percutaneous ventricular assist devices, this study conducts research on pVAD reliability test engineering. Test setups, clinical conditions, failure modes, effects analysis, and evaluation models have been investigated. A highly feasible methodological approach for percutaneous ventricular assist device reliability assessment has been formed. This study offers valuable insights into standardizing their reliability evaluation in clinical settings.
