Abstract

A process for making an endoprosthesis comprising: (a) applying a powder that includes a metal hydride to a surface of a metal endoprosthesis, or precursor tubing thereof; and (b) exposing the powder to a heat source to melt the powder and liberate hydrogen gas, thereby forming a porous coating on the surface of the endoprosthesis, or precursor tubing thereof.
