    • The invention relates to a method and device for recovering therapeutic and diagnostic agents from the venous outflow of a tissue or organ. A method for recovering an agent includes inserting a catheter into a vascular outflow of a tissue or organ, occluding the flow of blood/fluid through the vascular outflow, and withdrawing blood/fluid in the vascular outflow into the catheter to recover at least a portion of the agent administered to the vascular inflow of the organ or tissue. Also provided is a device to capture an agent administered to a vascular inflow, the device having a catheter having an expandable occlusion device to occlude a flow of fluid through the vascular outflow, a pump operably coupled to the catheter for withdrawing from the vascular outflow at least a portion of the agent administered to a vascular inflow of the organ or tissue, and an automated controller in signal communication with the catheter to control the expandable occlusion device and the pump to withdraw at least a portion of the agent from the vascular outflow.
    • 本发明涉及从组织或器官的静脉流出中回收治疗和诊断药物的方法和装置。 用于回收试剂的方法包括将导管插入组织或器官的血管流出物中,阻断通过血管流出物的血液/流体的流动,以及将血管流出物中的血液/流体抽出到导管中以回收至少一部分 的给药剂给予器官或组织的血管流入。 还提供了一种用于捕获施用于血管流入物的药剂的装置,所述装置具有导管,所述导管具有可扩张闭塞装置,以阻塞通过血管流出物的流体流动;泵,可操作地连接到导管,用于从血管流出物排出 施用于器官或组织的血管流入物的药剂的至少一部分,以及与导管信号通信的自动化控制器,以控制可扩张闭塞装置和泵从血管流出物中抽出至少一部分药剂。
