Valve, implant including the valve, fluid transfer arrangement, and method of treatment using the same

A method of dialysis, the method comprising:

• locating a valve disposed within a patient;
• inserting a fluid transfer device in a keyway of the valve;
• rotating the fluid transfer device with respect to a housing of the valve to open the valve;
• and
• communicating a fluid through the fluid transfer device to perform dialysis, wherein the valve comprises
• a housing defining a cavity having at least one connector fluidically connecting the cavity to an outside of the housing,
• a plug being movable within the housing at least between a first position that substantially occludes fluidic communication between the cavity and an outside of the housing through the at least one connector and a second position that allows fluidic communication between the cavity and the outside of the housing through the at least one connector, and
• a septum in operable communication with the housing and being sealingly penetrable by a fluid transfer device, the fluid transfer device being capable of moving the plug between at least the first position and the second position.
