Abstract

See full text

The present technology is directed to adjustable shunting systems having a shunting element, a shape memory actuator, and a lumen extending therethrough for transporting fluid. The shape memory actuator can have a plurality of struts proximate the shunting element and a plurality of projections extending from the plurality of struts. In operation, the shape memory actuator can be used to adjust a geometry of the lumen. In some embodiments, the system is configured such that (a) any strain in the shape memory actuator is concentrated in the struts, and/or (b) the struts experience greater resistive heating than the projections when an electrical current is applied to the actuator.
