Abstract
A tissue removing device and brush construction, and more particularly, a cytology brush construction which is intended to be utilized in conjunction with a specimen sampling device for the collection of microbiological biopsy specimen from a body cavity. The brush construction is attained by the provision of at least one initially flat element which may have at least one or opposing longitudinal outer edges in either a wavy-linear configuration, rectilinear form, or which may incorporate a multiplicity of closely spaced, parallel slits cut in from at least one longitudinal edge so as to leave a central longitudinal connecting web in the element. The flat element, upon being twisted into a helical configuration or by being interposed between a pair of wires or superimposed wire strands and which are then twisted, will exhibit the desired configuration and properties of a tissue removing device or cytology brush, with the elimination of the multiplicity of separate discrete bristles or filaments heretofore employed. Also disclosed as a brush structure is the use of a flattened plastic tube or the like having a plurality of slits cut into it from both edges thereof and which, upon being deformed into a helical brush-shape, will provide for an improved and enhanced collection of tissue specimen material.
