The Tao Brush is a medical instrument used to perform an alternative method of endometrial biopsy.
The traditional method of endometrial biopsies uses a specialized catheter (the Pipelle) to suction away a portion of the uterine lining. The Tao Brush method instead uses a small, flexible brush to gently brush the entire inside of the uterus. The Tao Brush is theoretically able to gather a more complete sampling of the uterus lining, removes less tissue, and some reports suggest that it is less painful than the traditional method.

Famous quotes containing the word brush:
“Poverty is the result of bad adjustment between the soul and its desires.... In the days of great poverty, I did not mind the sensation of hunger.... But ... to be deprived of tooth paste, to brush the teeth without it, was a dreadful thing, a daily discomfort.”
—Alice Foote MacDougall (1867–1945)
