1. An adjustable shunting system, comprising:
a body comprising one or more struts at least partially defining an orifice and/or lumen for enabling fluid flow therethrough, the body being formed of a shape memory material;
an outer layer positioned about the one or more struts, the outer layer composed of a conductive material defining a conductive path along a length of the one or more struts; and
at least one interruption in the conductive path resulting in a relatively lower conductivity within the interruption, wherein the body is continuous along the at least one interruption,
wherein, when energy is applied to the body—
a first portion of the shape memory material at the at least one interruption is configured to undergo a shape memory change, and
a second portion of the shape memory material extending along the conductive material is configured to remain substantially unchanged in shape.
