A stent mounting device and a method of coating a stent using the device are provided.
What is claimed is: 1. A method of coating a stent, comprising: mounting a stent on a support assembly; positioning a shielding member to cover a selected portion of the stent without the shielding member being in contact with the stent, wherein the shielding member is configured to reduce or elimi
What is claimed is: 1. A method of coating a stent, comprising: mounting a stent on a support assembly; positioning a shielding member to cover a selected portion of the stent without the shielding member being in contact with the stent, wherein the shielding member is configured to reduce or eliminate coating material applied to the selected portion of the stent; and applying a coating material to the stent for forming a coating. 2. The method of claim 1, wherein the act of applying comprises spraying the coating material onto the stent. 3. The method of claim 1, wherein the act of applying comprises spraying the coating material onto the stent, the coating material including a polymer added to a fluid and optionally a therapeutic substance added thereto. 4. The method of claim 1, wherein the act of applying comprises applying the coating material to the stent while rotating the stent about a longitudinal axis of the stent. 5. The method of claim 1, wherein the selected portion of the stent is a region of the stent in contact with the support assembly. 6. The method of claim 1, wherein the shielding member is rotatably integrated with the support assembly such that rotation of the shielding member moves the shielding member relative to the support assembly. 7. A method of coating a stent, comprising: mounting a stent on a support assembly; spraying via a spray nozzle a coating composition onto the stent; and positioning a shielding member between the stent and the spray nozzle to shield a selected portion of the stent during the spraying of the coating composition such that the shielding member does not make contact with the stent. 8. The method of claim 7, wherein the selected portion of the stent is the region where the support assembly is in contact with the stent. 9. The method of claim 7, wherein the positioning of the shielding member comprises moving the shielding member along the length of the stent so that the shielding member covers the selected portion of the stent. 10. The method of claim 7, wherein the shielding member is rotatably integrated with the support assembly such that rotation of the shielding member moves the shielding member relative to the support assembly. 11. A method of coating a stent, comprising: positioning a stent on a support assembly such that at least a segment of the stent is inserted into a hollow tubular body that is adjustably integrated with the support assembly, the hollow tubular body adapted to reduce an amount of or prevent a coating composition from being applied to an area of the stent covered by the tubular body; adjusting the position of the hollow tubular body over the stent to an area which a user wants to cover by a means for adjusting the position; and applying a coating composition to the stent. 12. A method of coating a stent, comprising: positioning a stent on a support assembly such that at least a segment of the stent is inserted into a hollow tubular body that is adjustably integrated with the support assembly, the hollow tubular body adapted to reduce an amount of or prevent a coating composition from being applied to an area of the stent covered by the tubular body, wherein the hollow tubular body does not make contact with the stent; adjusting the position of the hollow tubular body over the stent to an area which a user wants to cover; and applying a coating composition to the stent. 13. The method of claim 12, wherein the hollow tubular body is rotatably integrated with the support assembly such that rotation of the hollow tubular body moves the hollow tubular body relative to the support assembly. 14. A method of coating a stent, comprising: positioning a stent on a support assembly; positioning a shield between a nozzle assembly and the stent so that the shield does not make contact with the stent, wherein the position of the shield is adjustable with respect to the support assembly; and applying a coating composition to the stent. 15. The method of claim 14, wherein the shield circumscribes a segment of the length of the stent. 16. The method of claim 14, wherein the shield is adjustably integrated with the support assembly. 17. The method of claim 14, wherein the shield has a hollow tubular body in which the stent can be inserted. 18. The method of claim 14, wherein the shield is rotatably integrated with the support assembly such that rotation of the shield moves the shield relative to the support assembly. 19. A method of coating a stent, comprising applying a coating composition on a stent, positioned on a support assembly, by a nozzle such that a shield member positioned between the nozzle and an outer surface of the stent reduces an amount of or prevents the coating composition from being applied on an outer surface of the stent underneath the shield member, wherein the shield member does not make contact with the outer surface of the stent underneath the shield member during the application of the coating composition. 20. The method of claim 19, wherein the shield member is adjustably integrated with the support assembly. 21. The method of claim 19, additionally comprising rotating the stent during the application of the coating composition. 22. The method of claim 19, additionally comprising moving the shield member to a position prior to application of the coating composition.
