Montgomery® Long-Term Cannula
The patented Montgomery® Long-Term Cannula is the result of many years of clinical research and design. Used to replace either the Short-Term Cannula or a standard tracheostomy tube, the cannula features a
27°-angled flange to ensure that the tube rests horizontally when seated in the trachea - nothing protrudes into the trachea.
Made from flexible Implant grade silicone, the tube has a highly polished surface that permits and encourages growth of epithelium between the trachea and the skin. Once inserted, a ring washer is applied, ensuring patient safety. The tube can be trimmed to a low profile. A dual-purpose groove along the axis of the tube rests in the “6 o’clock” position for orientation and serves as a drainage vent.
Long-Term Cannula diameters correspond to standard tracheostomy tube sizes 4, 6, 8, and 10. The stoma length in millimeters is measured along the inferior aspect of the stoma from the anterior tracheal wall to the outside skin. These measurements are made easily using the
STOMEASURE™. There are 24 sizes of Long-Term Cannula to choose from. Each Long-Term Cannula includes the tube, two plug/ring sets, and product information. Also available are 15mm adaptors and additional plug/ring sets. Refer to chart below for corresponding product codes.
