摘要：
The present disclosure relates to a rotary blood pump system. The rotary blood pump system may further comprise a double pivot contact bearing system with an operating range between about 50 mL/min and about 1500 mL/min. 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 comprised of metal or polymer having an undulating opening surface that provides improved blood flow and washing properties while minimizing regions susceptible to stagnation, and optionally 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 comprised of metal or polymer 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.本發明係關於一種旋轉血泵系統。該旋轉血泵系統可進一步包括具有介於約50 mL/min與約1500 mL/min之間之一操作範圍之一雙樞軸接觸軸承系統。該旋轉血泵系統亦可包括一流入血液導管、一流出導管、一控制系統及一電源。本發明進一步係關於各種流入導管總成,其等包括:一導管端部,其包括金屬或聚合物,且具有一波狀開口表面以提供經改良血液流量及清洗性質同時最小化易於停滯之區;及視情況一彈性端部保護籠結構,其降低鄰近血管或其他含血結構之壁之導管端部吸入事件及吸入相關損傷之風險。本發明進一步係關於各種流出導管總成,其等具有包括金屬或聚合物之一導管端部,其中減小該導管或導管端部之內腔之橫截面積以在鄰近於該導管端部之一血管段中產生一局部噴射狀流體流。1000‧‧‧流入導管端部/流入端部/導管/引流端部1100‧‧‧管狀本體1200‧‧‧近端1300‧‧‧遠端1302‧‧‧遠端開口1304‧‧‧遠端表面1308‧‧‧峰部分/峰區
