Abstract

The present technology provides adjustable shunting systems with actuation assemblies that can be selectively adjusted to change a level of therapy provided by the shunt. The actuation assemblies can include a shape memory actuator having a plurality of leaflets or projections forming a conical shape with openings on both ends of the cone. The actuation assemblies can further include one or more membranes that individually jacket or cover individual projections of the plurality of projections to form a lumen extending through the conical shape.
