An expandable structure for passive deployment in a well. The structure may be locked in a position determined by the inner dimensions of the well in which it is deployed. Practical uses for the structure may include production tubing or a host of other devices for affixing downhole with a final diameter as determined by the inner diameter of the well. Additionally, the structure may be configured for advancement to a targeted well location while in a collapsed state. Thus, upon deployment, subsequent structures may be advanced through the expanded/deployed structure. As such, affixed structures may be deployed downhole in both top-down and bottom-up fashions without concern over a prior deployed structure obstructing subsequent structure deployment downhole thereof.
