Abstract: The present invention has several plausible embodiments. In one embodiment an apparatus for coating a medical device is provided. This apparatus includes a coating chamber, a vibrating structure within the coating chamber the vibrating structure capable of suspending a medical device positioned in the coating chamber, and a coating source, the coating source positioned to introduce coating into the coating chamber. In another embodiment a method of coating a medical device is provided. This method includes moving a medical device into a predetermined coating area, vibrating a structure below the medical device, the vibration of the structure forcing the medical device away from the vibrating structure, and coating at least a portion of the medical device that has moved away from the vibrating structure.

Abstract: There are described novel photographic processing compositions, film units and processes for use in diffusion transfer photographic systems. More particularly, there is described a method for forming a diffusion transfer image photographic processing of diffusion transfer photographic film units in the presence of hypoxanthine and inosine. Diffusion transfer photographic systems utilizing the novel photographic element or method of the present invention exhibit substantially fewer, if any, crystals on the final image of the finished photograph post-processing.
