    Abstract: Rotational shape-memory actuators and associated devices, systems, and methods are disclosed. In some embodiments, a rotational shape-memory actuator includes a first anchor, a second anchor, a spring element extending between the first and second anchors, a first shape memory element extending between the first and second anchors, a second shape memory element extending between the first and second anchors, and a communication line wrapped around the first and second shape memory elements. The first and second shape memory elements are configured to transition between a first configuration in which the first and second shape memory elements are twisted together and a second configuration in which the first and second shape memory elements are less twisted together such that transitions of the first and second shape memory elements between the first and second configurations cause the second anchor to rotate with respect to the first anchor.

    Abstract: The present invention generally relates to methods, devices and systems for determining the rotational orientation of a device. The invention can involve providing a device comprising a plurality of markers, wherein each marker within the plurality of markers differs from an adjacent marker by size, shape, and/or position on the device. The invention can also involve inserting the device into a vessel and imaging the device to capture an image of the device in an imaging plane. The invention can further involve processing the captured image to determine an orientation of the device relative to the imaging plane based on the markers.
