Apical aortic blood pump preclinical assessment for long‐term use: Durability test and stator topology to reduce wear in the bearing system

This study presents an assessment for long‐term use of the apical aortic blood pump (AABP), focusing on wear reduction in the bearing system. AABP is a centrifugal left ventricle assist device initially developed for bridge to transplant application. To analyze AABP performance in long‐term applications, a durability test was performed. This test indicated that wear in the lower bearing pivot causes device failure in long‐term. A wear test in...
