| 摘要 | A bearing assembly for use in a blood pump includes a first component that has a convex bearing surface and a first outer surface proximate the convex bearing surface. The bearing assembly includes a second component that a concave bearing surface and a second outer surface proximate the concave bearing surface, the concave bearing surface being configured to receive the convex bearing surface. A plurality of grooves are defined through the convex bearing surface and first outer surface or through the concave bearing surface and the second outer surface. | ||
