Claims20
A method of creating structural features on a surface of an article, comprising the steps of:
- a. Coating at least the surface of the article with photoresist;
- b. Processing the photoresist so as to make it photosensitive;
- c. Mounting the photoresist coated article on a mount surface having a photomask disposed thereon, the mount surface disposed between a source of exposing radiation and the article;
- d. Applying the exposing radiation through the photomask onto the photoresist coated article;
- e. Removing the article from the mount surface;
- f. Developing the photoresist to reveal the pattern imparted by the photomasked surface;
- and
- g. Machining the exposed pattern on the article.

A method of creating topographical features on the inside surface of a stent, comprising the steps of:
- a. Coating at least the inside surface of the stent with photoresist;
- b. Processing the photoresist so as to make it photosensitive;
- c. Mounting the photoresist coated stent on a mandrel having a photomask disposed thereon, the mandrel disposed between a source of exposing radiation and the stent;
- d. Applying an exposing radiation through the photomasked mandrel onto the photoresist coated stent;
- e. Removing the stent from the photomasked mandrel;
- f. Developing the photoresist to reveal the pattern imparted by the photomasked mandrel;
- and
- g. Machining the exposed pattern on the stent.
