摘要：
An embodiment in accordance with the present invention provides a device and method for hemodialysis including a needle access port having a housing defining a septum, wherein the septum is configured for needle access. Generally, the needle access port will have three septa for communication with valves configured to be anastomosed to a large-diameter blood vessel. The valves are in fluid communication with a flow of blood through the large-diameter blood vessel. The device also includes an elongate tube having a first and a second elongate lumen, wherein a first end of the tube is coupled to the needle access port and a second end of the tube is coupled to the valve. The device can be cleaned by injecting a cleaning fluid into a first septum of the needle access port and extracting it though the second septum of the needle access port.
