1. An adjustable shunt assembly, comprising:
a self-expanding shunting element configured to extend through a tissue wall between a first body region of a patient and a second body region of the patient, wherein the shunting element comprises an artificial lumen through the tissue wall to shunt fluid between the first body region and the second body region of the patient; and
a shape memory actuation element coupled to the shunting element and configured to adjust a geometry of the artificial lumen, wherein the shape memory actuation element is mechanically adjustable at body temperature and thermally adjustable when heated above a transition temperature greater than the body temperature,
wherein the shunt assembly is configured such that mechanically adjusting the shape memory actuation element induces a first change in a dimension of the artificial lumen and thermally adjusting the shape memory actuation element induces a second change in the dimension of the artificial lumen.
