1. An apparatus configured to be positioned within a passageway of a living being, the apparatus comprising:

  • a structure configured to be selectively expanded from a first configuration to a second configuration, comprising;

    a first-stage outer wall having a length along a first axis, a depth along a second axis and a height along a third axis; and

    an expandable strut member configured to be selectively expanded along the second axis to a maximum expansion distance that is greater than the depth of the living passageway;

    wherein at the first configuration of the apparatus, the depth and a height of the first-stage outer wall form an outer perimeter of the apparatus that is less than an inner perimeter of the passageway of the living being, such that the length of the first-stage outer wall is configured to be maneuverable along a longitudinal axis of the passageway from a first location to a second location;

    wherein at the second configuration of the apparatus, the expandable strut member expands along the second axis until it reaches an interior surface of the passageway or a physical structure to form two opposing outer surfaces separated by a first inner diameter, wherein the first inner diameter is a distance that is less than the maximum expansion distance and further comprises a first plurality of markers that are each separated by a predetermined distance along the first inner diameter of the apparatus; and

    wherein the first plurality of markers are configured to be detected by an imaging device to allow an indication of an orientation of the apparatus and a diameter of the passageway.
