The DISPOSABLE CYTOLOGY BRUSH BC-202D/203D Series is intended to be used to collect tissue specimens in the tracheobronchial tree in combination with a bronchoscope.

The DISPOSABLE CYTOLOGY BRUSH BC-202D-1210/2010/3010/5010, BC-203D-2006 have been designed to collect specimens or cells endoscopically for cytologic examination in conjunction with bronchoscopes. The Subject Device (SD) is inserted into the bronchoscope through a biopsy valve to reach the target area, where, by rubbing the brush on the target area, specimens or cells can be collected. The Subject Device is then withdrawn from the bronchoscope channel with the collected samples. The Subject Device consists of: - Handle - Insertion portion The handle consists of a ring and a grip. The insertion portion consists of a plastic tube, stainless steel wire, nylon brush (length 6mm or 10mm, diameters 1.2 – 5 mm) and stainless steel distal tip. The grip is attached to the tube and the ring is attached to the wire. The user can move the brush at the tip of the wire back and forth by holding the grip and moving the ring back and forth. The distal tip is designed to prevent damage to the inside of the tube and/or bronchial wall.

The Pulmonary Cytology Brush is intended to allow brush sampling of tissue or cells from the upper or lower respiratory tract and/or to perform surveillance cultures

The cytology brush has been specifically designed to collect specimens or cells endoscopically for cytologic examination in conjunction with Olympus bronchoscopes with channel φ1.7mm or larger.

The single use cytology brush BC-205D has been designed to collect specimens or cells endoscopically for cytologic examination in conjunction with bronchoscopes. Identical to the predicate device, the subject device is inserted into bronchoscope channel to collect specimens with the brush which is equipped at the distal end of the subject device. Then users withdraw the subject device from bronchoscope channel and collect samples for cytology examination.

To be utilized through a flexible endoscope or the superDimension system by physicians who are trained in endoscopic techniques for retrieving specimens from patients with endobronchial lesions, peripheral lung nodules, or lung masses.

The superDimension® Triple Needle Cytology Brush is designed to obtain tissue samples for biopsy from endobronchial lesions, peripheral lung nodules, or lung masses. The superDimension® Triple Needle Cytology Brush is an endoscopic catheter comprised of an outer Ethylene Tetrafluoroethylene (ETFE) sheathing and an inner catheter assembly. The inner catheter assembly consists of a thumb ring at the proximal end and a twisted wire shaft to connect to the distal end. The distal end terminates in three connected brushes available in two lengths: 10 mm and 15mm. The brushes have sharpened ends, referred to as needle-tipped, that can be used to rough up tissue to obtain a sample of tissue or cells. When the catheter is inserted into a channel such as a bronchoscope or superDimension Extended Working Channel (EWC) with the distal brush in a retracted position inside the outer sheath. When the catheter is in position, the brushes can be extended into the tissue to obtain tissue samples by advancing the proximal thumb ring. When the physician believes that an adequate sample has been taken, the brushes are retracted back into the sheath and then the entire catheter is withdrawn from the channel The superDimension® Triple Needle Cytology Brush is for standard tissue analysis. similar to currently marketed cytology brushes except that it has three smaller brushes in place of one larger brush.
