MONTGOMERY® Long-Term Cannula


Product Description

Montgomery® Long-Term Cannula

The patented Montgomery Long-Term Cannula is the result of many years of clinical research and design. Used to replace standard tracheostomy tube, the cannula features a special angled internal flange to ensure that the tube rests horizontally when placed in the trachea. With the Montgomery Cannula, no tube protrudes into the trachea! Made from flexible medical grade silicone, the tube has a highly polished surface that helps maintain a healthy and comfortable tracheostoma. After insertion, a ring washer is slid up to the skin to help ensure patient safety. The tube can be trimmed to a low profile. A groove along the length of the tube confirms the correct position (rotation) of the flange inside. A cleaning and care video is available.

Montgomery Long-Term Cannula diameters correspond to standard tracheostomy tube sizes 4, 6, 8, and 10. There are six different lengths to choose from for each diameter (24 total sizes). The stoma length is measured (in millimeters) along the bottom of the stoma from the inside tracheal wall to the outside skin.
