Abstract: The invention provides a device for holding a substrate during deposition processes that includes a rotation member rotatable about a first, central axis, and a plurality of substrate holders positioned on the rotation member, the substrate holders being rotatable about second axes. In another aspect, the invention provides a method of applying a substantially uniform coating on a substrate including the steps of providing a device of the invention; mounting a substrate onto the substrate mounts; providing at least one substrate coating station in spaced relation to the substrate mounts; rotating the rotation member about a central axis to position one or more of the substrate mounts at the substrate coating station; supplying the coating through the nozzle; moving the nozzle of the coating station in a direction parallel to the substrate at a predetermined rate to apply a uniform coating on the substrate; and rotating the substrate mounts about the second axes during the coating process.

Abstract: A process and apparatus for dip-coating intermediate and/or discrete discontinuous portions of longitudinal devices, including medical devices such as catheters and guidewires. The apparatus provides a chamber in which both the desired portion(s) of the device and the coating solution can be controllably contacted. A controlled coating can be achieved within the chamber by providing and controlling one or more of the following relationships: a) the manner in which a chamber (containing solution) is itself moved with respect to a static device, b) the manner in which the device is moved with respect to a fixed chamber position containing a fixed volume of solution, and/or c) the manner in which both the chamber and device are fixed in position, and the coating is achieved by adding and removing a volume of solution from the chamber. The resultant movement of solution and device is intended to mimic or replicate the relative movements involved in a conventional dip-coating procedure, at least along the length of device to be coated.
