This invention is directed to an expandable stent useful for implantation into an artery or the like. The stents are made using electroforming techniques in which an electrically-conductive mandrel is coated with a suitable resist material, af ter which the resist is exposed to an appropriate light pattern and frequency so as to for m a stent pattern in the resist. The mandrel is then electroplated with a suitable stent m aterial. The mandrel is etched away once a sufficient layer of stent material is deposited, l eaving a completed stent.
