1. An adjustable flow shunt for treating a human patient, the shunt comprising:
a drainage element having a lumen extending at least partially therethrough and an opening in fluid communication with the lumen;
a control element configured to interface with the opening; and
a shape memory actuation element operably coupled to the control element, wherein the shape memory actuation element is transitionable between a first material state and a second material state via application of energy, and
wherein transitioning the shape memory actuation element between the first material state and the second material state changes a position of the control element to (a) make the opening more accessible, or (b) make the opening less accessible.
