1. A method for supporting a stent during a stent coating process, comprising:
- positioning a stent on an apparatus comprising a first arm element for engagement with a first section of a stent and a second arm element for engagement with a second section of the stent, wherein at least one of the first and second arm elements can be pivoted from a first position to a second position so as to have a first angle between the first and second arm elements for supporting the stent and pivoted from the second position to the first position so as to have a second angle between the first and second arm elements for releasing of the stent, wherein at least one of the first and second arm elements are coupled to a mandrel, the mandrel configured to penetrate at least partially in a longitudinal bore of the stent; and
applying a coating material to the stent.

6. A method for supporting a stent during a stent coating process, comprising:
-
positioning a stent on an apparatus comprising a first arm element for engagement with a first section of a stent, and a second arm element for engagement with a second section of the stent, wherein in a natural configuration, the arm elements are in an engaged configuration with the stent and wherein with an application of a force, the arm elements can be biased relative to each other for disengagement of the stent, wherein at least one of the first and second arm elements are coupled to a mandrel, the mandrel configured to penetrate at least partially in a longitudinal bore of the stent; and applying a coating material to the stent. - View Dependent Claims (7, 8, 9)

10. A method for supporting a stent during a coating process, comprising:
-
supporting the stent on a first member, a second member, and a third member, the second member capable of bending between a first position and a second position so as to allow the stent to be releasably supported by the first and second members, the third member capable of bending between a first position and second position to allow the stent to be releasably supported by the first, second and third members; and applying a coating material to the stent. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for supporting a stent during a coating process, comprising:
-
positioning a stent on a first arm element extending from a base member and a second arm element extending from the base member, wherein the second arm element is adapted to be pressed into a depression in the base member, and when pressed into the depression the second arm element flexes from a first position to a second position, the first position for holding the stent on the first and second arm elements, the second position for releasing the stent from the first and second arm elements; and applying a coating material on the stent. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 32, 33)

27. A method for supporting a stent during a stent coating process, comprising:
-
positioning a stent on a device comprising a first arm element for engagement with a first section of a stent and a second arm element for engagement with a second section of the stent, wherein the first or second arm elements is configured to be pivoted or bent from a first position to a second position for penetrating into a gap between a support structure of the stent and pivoted or bent from the second position to the first position for retracting out of the gap between the support structure of the stent, and wherein the first arm element comprises a mandrel for being disposed in a longitudinal bore of a stent and the second arm element is connected to the first arm element; and applying a coating composition to the stent. - View Dependent Claims (28)

29. A method for supporting a stent during a stent coating process, comprising:
-
positioning a stent on a device comprising a first member extending from a base and a second member extending form the base; rotating the base, wherein during the rotation of the base, the stent moves back and forth relative to the first and second members; and applying a coating material to the stent wherein the first member is a mandrel member having a diameter smaller than the inner diameter of the stent as positioned on the device. - View Dependent Claims (30, 31)

34. A method of supporting a stent during a stent coating process comprising:
- positioning a stent on a device comprising;
a first member extending from a base and a second member extending from the base;
rotating the base, wherein during the rotation of the base, the stent moves back and forth relative to the first and second members; and
applying a coating material to the stent, wherein the first member passes through a lateral gap between struts of the stent, wherein the second member passes through another lateral gap between the struts of the stent and the device further includes a third member extending from the base and passing through a longitudinal opening at an end of the stent.
- positioning a stent on a device comprising;
