Disclosed herein are medical devices, particularly lumen-supporting devices, which include a biocompatible nanostructured ceramic material configured to be disposed adjacent to a luminal surface and having an average grain size dimension of about 1 nanometer to about 1000 nanometers, a strain to failure of at least about 1 percent, and a cross-sectional hardness greater than or equal to about 350 kilograms per square millimeter. Also disclosed are methods of making and using the lumen-supporting devices.
