摘要：
A fluid agent is delivered to the renal system using an abdominal aortic flow isolation assembly. In certain aspects, a tubular member (13) extends within the aorta (31) across the renal ostia, with a radially expandable interior passageway (18) separating aortic blood flow into outer (33) and inner streams. A radially expandable member (14) on the tubular member (13) is located down-stream of an agent delivery port (25) coupled to the outer stream, with an expanded configuration having an outer diameter larger than the tubular member (13) and that inhibits the outer blood flow stream (33) from flowing downstream of the branch vessel (32). One or more fluid agents such as Papaverine, a calcium-channel blocker, Nifedipine, Verapamil, Fenoldapam, or a dopamine DA
摘要（中）：
使用腹主动脉血流隔离组件将流体药物递送至肾脏系统。 在某些方面，管状构件（13）在主动脉（31）内延伸穿过肾口，具有径向可扩张的内部通道（18），其将主动脉血流分离成外部（33）和内部流。 管状构件（13）上的可径向扩张的构件（14）位于与外流联接的药剂输送口（25）的下游，其膨胀构型具有比管状构件（13）更大的外径， 其阻止外部血液流（33）从分支容器（32）的下游流动。 一种或多种流体剂，例如罂粟碱，钙通道阻滞剂，硝苯地平，维拉帕米，芬诺达帕或多巴胺DA
