Abstract
A scrubber pad for a rotating epithelial removal tool is made of a single piece of substantially rigid plastic which has formed thereon a scrubbing surface equipped with a radial channel or channels to retain cell debris and lubricating fluid. An eccentrically located fluid supply conduit can provide additional fluid and can also serve with the radial channels as a visual centering indicator to the patient. The edges of the scrubbing surface can be undercut to give them a desired flexibility.
