Method and apparatus for coating of substrates
First Claim
1. An apparatus for coating a surface of a rollable medical device comprising:
- a device rotator comprising at least one pair of rollers, said at least one pair comprising a first roller and a second roller separated by a gap;
wherein the device rotator is configured to hold the device within the gap such that the device contacts the first and second roller;
a spray nozzle able to produce a spray of a coating material, wherein the spray nozzle is arranged to direct the spray at the gap;
anda device retaining member disposed at a distance from at least one of the rollers that is less than the diameter of the rollable medical device, the device retaining member comprising a wire disposed in a plane that is substantially parallel to at least one of the rollers.
