Abstract

A method is disclosed for spin coating a stent. The method comprises conducting the following acts at the same time: applying a coating substance to the stent; rotating the stent about a first axis of rotation; and rotating the stent about a second axis of rotation.

Claims (20)

1. A method of coating a stent, comprising conducting the following acts at the same time:

applying a coating substance to the stent;

rotating the stent about a first axis of rotation; and

rotating the stent about a second axis of rotation,

wherein the first axis of rotation intersects the second axis of rotation at an angle.

2. The method of claim 1 , wherein the first axis of rotation is perpendicular to the second axis of rotation.

3. The method of claim 1 , wherein the first axis of rotation intersects a center of the mass of the stent and the second axis of rotation is along a longitudinal central axis of the stent.

4. The method of claim 1 , wherein the first axis of rotation intersects a part of the body of the stent and the second axis of rotation is along a longitudinal central axis of the stent.

5. The method of claim 1 , wherein the first axis of rotation intersects a center of the mass of the stent, the second axis of rotation is along a longitudinal central axis of the stent, and the first axis of rotation is perpendicular to the second axis of rotation.

6. The method of claim 1 , wherein the stent is positioned off-set, at a distance away from the first axis of rotation.

7. The method of claim 1 , wherein the first axis of rotation is perpendicular to a longitudinal axis of the stent.

8. A method of coating a stent, comprising conducting the following acts at the same time:

applying a coating substance to the stent;

rotating the stent about a first axis of rotation; and

rotating the stent about a second axis of rotation,

wherein the first axis of rotation is not parallel and not perpendicular to the second axis of rotation.

9. The method of claim 1 , wherein the first axis of rotation intersects a center of the mass of the stent and the second axis of rotation is along a longitudinal central axis of the stent.

10. The method of claim 1 , wherein the first axis of rotation intersects a part of the body of the stent and the second axis of rotation is along a longitudinal central axis of the stent.

11. The method of claim 1 , wherein the stent is positioned off-set, at a distance away from the first axis of rotation.

12. The method of claim 1 , wherein the first axis of rotation intersects the second axis of rotation at an angle.
