A wire-guided cytology brush is disclosed. The brush comprises a flexible outer sheath and a flexible inner sheath. The inner sheath is disposed within the lumen of the outer sheath. A means for collecting a tissue sample is disposed at a distal end of the inner sheath, a first handle is disposed at a proximal end of the inner sheath, and a second handle is disposed at a proximal end of the outer sheath. The inner and outer sheaths are inserted over a guide-wire such that the guide-wire passes through the lumen of the inner sheath. A retainer clip maintains the relative positioning of the inner sheath within the outer sheath during insertion and removal of the brush assembly over the guide wire.
