1. A biocompatible articulated support structure, comprising a tubular support body with a proximal opening, a distal opening, and a lumen and a longitudinal axis between the proximal and distal openings;

  • wherein the tubular support body comprises a plurality of discrete struts coupled by a plurality of rotatable hinge joints, each rotatable hinge joint comprising an axis of rotation with a radial orientation;

    wherein the plurality of rotatable hinge joints comprise;

    a set of proximal rotatable hinge joints configured to reside in a proximal plane with the proximal opening;

    a set of distal rotatable hinge joints configured to reside in a distal plane with the distal opening;

    a first set of middle rotatable hinge joints, located between the proximal plane and the distal plane; and

    at least one commissural point hinge joint distal to the distal plane;

    wherein the plurality of discrete struts and the rotatable hinge joints therebetween intrinsically provide a self-expansion force; and

    wherein the plurality of discrete struts comprise a plurality of inner struts and a plurality of outer struts.
