Abstract
A retractable brush structure is attached to a cylindrical rigid rod which in the closed position passes through a channel in an endoscope. After the brush passes through the endoscope, the brush moves against the tissue in order to remove cells from an area under examination. The brush is withdrawn from the endoscope and sample tissue is removed from said brush for examination after it is withdrawn from the endoscope.
