| 摘要 |
The invention relates to a method of coating a surface of a stent by contacting the stent with a coating solution containing a coating material, insenrting a thread through the lumen of the stent, and producing relative motion between the stent and the thread to substantially remove coating material located within the openings of the stent. Eliminating or minimizing coating material located within the openings preserves the functionality of the stent. The method can be used to apply a primer layer, a polymer, either with or without a therapeutic agent, and/or a top layer on the stent.
