Abstract
Methods for fabricating a medical device having at least one porous layer include providing a medical device having at least one alloy and removing at least one component of the alloy to form the porous layer. Although methods may be used to make stent devices with porous layers, any other suitable medical device may be made having one or more porous layers. An alloy may include any suitable combination of metals and sometimes a combination of metal and non-metal. In some embodiments, one or more of the most electrochemically active component(s) of an alloy are removed by the dissolving (or 'dealloying') process, to leave a porous matrix behind. The porous matrix layer may then be infused with one or more therapeutic agents for enhancing treatment of a patient.
