Abstract

Various embodiments of methods and devices for drying coated stents in an oven are described herein.

First claim

What is claimed is:

1. A device for drying coated stents, the device comprising:
an oven enclosure including a rotatable dial configured to carry stent supports within the oven enclosure so that stents on the stent supports can be conveyed by rotation of the dial within the oven enclosure to dry a coating on the stents; and
a transfer mechanism including an actuator and a first gripper, the actuator configured to move the first gripper into and out of the oven enclosure, the first gripper configured to remove a stent support from the dial.

2. The device of claim 1 , wherein the dial comprises a lip around a periphery of the dial, the lip including a plurality of holes configured to receive the stent supports.

3. The device of claim 1 , wherein the oven enclosure comprises an opening sized to allow movement of the first gripper into and out of the opening.

4. The device of claim 1 , further comprising a movable door that is movable to cover the opening in the oven enclosure.

5. The device of claim 4 , wherein the door is movable from a bottom of the opening to a top of the opening.

6. A device for drying coated stents, the device comprising:
an oven enclosure; and
a conveyor belt disposed within the oven enclosure,
wherein the conveyor belt is configured to support a plurality of coated stents so that the stents can be conveyed within the oven enclosure to dry a coating on the stents, the stents conveyed through movement of the belt through the oven enclosure.

7. The device of claim 6 , wherein the conveyor belt comprises a plurality of holes sized to receive stent supports for carrying stents.

8. The device of claim 6 , further comprising a first gear for driving the conveyor belt, the first gear disposed in the oven enclosure and engaging perforations in the conveyor belt.

9. The device of claim 6 , further comprising a second gear for driving the conveyor belt, the second gear disposed outside the oven enclosure and engaging perforations in the conveyor belt.

10. The device of claim 6 , wherein the conveyor belt follows a zig-zag pattern within the oven enclosure.

11. The device of claim 1 , wherein the transfer mechanism further includes a second gripper, the actuator is configured to move the first gripper and the second gripper together into and out of the oven enclosure, and the second gripper is configured to place a stent support on the dial while the first gripper removes a stent support from the dial.

12. The device of claim 1 , further comprising a heat source configured to heat the oven enclosure.

13. The device of claim 1 , further comprising the stent supports.

14. The device of claim 6 , further comprising a heat source configured to heat the oven enclosure.

15. The device of claim 14 , wherein the conveyor belt includes a segment outside of the oven enclosure, the segment passes through a first opening of the oven enclosure to transport stents out of the oven enclosure and through a second opening of the oven enclosure to transport stents into the oven enclosure.

16. The device of claim 15 , further comprising a first revolving door at the first opening and a second revolving door at the second opening.

17. The device of claim 15 , further comprising a loading enclosure outside of the oven enclosure, the loading enclosure containing the segment of the conveyor belt that passes through the first opening and the second opening of the oven enclosure.

18. The device of claim 7 , further comprising the stent supports.
