摘要：
The present disclosure relates to a rotary blood pump system. The rotary blood pump system may comprise a double pivot contact bearing system. The rotary blood pump system may also comprise an inflow blood conduit, an outflow conduit, a control system, and a power source. The present disclosure further relates to various inflow conduit assemblies comprising a conduit tip having an undulating opening surface that provides improved blood flow and washing properties while minimizing regions susceptible to stagnation, and a resilient tip protecting cage structure that reduces the risk of conduit tip suction events and suction-related injury of the wall of adjacent blood vessels or other blood containing structures. The present disclosure further relates to various outflow conduit assemblies with a conduit tip wherein the cross-sectional area of the lumen of the conduit or conduit tip is reduced to generate a localized jet-like fluid flow in a blood vessel segment adjacent to the conduit tip.
