Abstract
A bidirectional thermally actuated component includes a heating element and wax material provided in an enclosed housing wherein the heating element is activated to melt the wax which expands to cause movement of the housing or an element mounted therein. When the heating element is deactivated, the was hardens and constricts to allow for movement in the opposite direction based on application of a force in the opposite direction, which may be provided by a biasing spring or a second actuator. An adjustable medical device may include the thermally actuated component to control adjustment of the device.
