Abstract

Various embodiments of methods and devices for coating stents are described herein.

First claim

What is claimed is:

1. A support assembly for supporting a stent during coating comprising:
a first support element coupled to a rotatable spindle;
a support wire, wherein a proximal end segment of the support wire extends from and is coupled to the first support element; and
a clamping device supporting a distal end segment of the support wire, wherein the proximal end segment and the distal end segment of the of the support wire are positioned so that the support wire rotates concentrically with the first support element when the first support element is rotated by the rotatable spindle, and wherein the support wire rotates relative to the clamping device wherein the clamping device comprises arms that are movably coupled to each other such that the support wire is secured by the arms when the arms move toward each other.

2. The support assembly of claim 1 , wherein the clamping device comprises arms that are movably coupled to each other such that the support wire is secured by the arms when the arms rotate inward move toward each other.

3. The support assembly of claim 2 , wherein the arms each include a cut-out section, the cut-out sections configured to receive the support wire when the arms move toward each other.

4. The support assembly of claim 1 , wherein a portion of the first support element is configured to support a first end of a stent.

5. The support assembly of claim 4 , further comprising a second support element coupled to the support wire at a location between the first support element and the clamping device, wherein a portion of the second support element is configured to support a second end of the stent.

6. The support assembly of claim 5 , wherein the portion of the first support element is a first cone configured to support the first end of the stent, and the portion of the second support element is a second cone configured to support the second end of the stent.

7. The support assembly of claim 1 , wherein the first support element is movable into and out of the rotatable spindle.

8. The support assembly of claim 6 , wherein the support wire is movable into and out of the clamping device.
