1. A method of adjusting an implanted shunt fluidly coupling a first body region and a second body region, the method comprising:
advancing an elongated body through the patient's vasculature and toward the implanted shunt;
positioning the elongated body within a lumen extending through the shunt or proximate to an inlet orifice or an outlet orifice of the lumen;
temporarily reducing a flow of fluid through the lumen using one or more flow obstruction elements coupled to the elongated body; and
after temporarily reducing the flow of fluid through the lumen, and while the flow of fluid remains temporarily reduced, heating a shape memory component of the shunt, wherein heating the shape memory component transforms the shunt from a first configuration to and/or toward a second configuration,
wherein transforming the shunt from the first configuration to and/or toward the second configuration alters an inner dimension of the shunt associated with the lumen without substantially altering an outer dimension of the shunt.
