1. An implantable device for shunting fluid within a patient, the device comprising:
a drainage element having a lumen extending therethrough;
a flow control element moveable between at least a first position and a second position and configured to change a flow resistance through the device;
an actuation element, wherein at least a portion of the actuation element is transitionable from a first material state to a second material state when heated above a transition temperature, and wherein the actuation element is configured to move the flow control element from the first position toward the second position when heated above the transition temperature; and
a deflective element configured to direct energy received at the deflective element toward the actuation element to heat at least the portion of the actuation element above the transition temperature; wherein the deflective element is configured to direct energy received in the form of visible and/or infrared radiation toward the actuation element to heat at least the portion of the actuation element; and
wherein the device is configured such that energy can be delivered directly to the actuation element in addition to being delivered to the actuation element via the deflective element.
