METHOD TO CREATE MICROPATTERNS ON AN INSIDE SURFACE OF A STENT

摘要

A method for manufacturing a tubular medical device having a micropatterned inner surface is disclosed. A glass tube having an optical mask on an outer surface thereof may be placed within a lumen of a tubular medical device, wherein the optical mask forms a pattern of shapes. An ultraviolet light source may be advanced within a lumen of the glass tube. The inner surface, including a photoresist coating, of the tubular medical device may be illuminated with ultraviolet light through the glass tube. The optical mask may block ultraviolet light from passing through portions of the glass tube. The inner surface of the tubular medical device may be etched to create a plurality of protrusions.

1. A method for manufacturing a curved medical device, the method comprising:
placing a glass tube having an optical mask on an outer surface thereof adjacent to a concave surface of a curved medical device, wherein the optical mask forms a pattern and the concave surface of the curved medical device having a light sensitive photoresist layer disposed thereon; advancing an ultraviolet light source within a lumen of the glass tube; illuminating the concave surface of the curved medical device with ultraviolet light through the glass tube, wherein the optical mask blocks ultraviolet light from passing through portions of the glass tube; and etching the concave surface of the curved medical device to create a plurality of protrusions.
