摘要： A tracheostomy is performed using an access device and a separate ventilation device. The access device is introduced through a surgical opening in the tracheal wall and has an anchor which is expanded in situ to hold the access device in place. The ventilation device is introduced through a passage in the access device and has an expandable cuff which is oriented above the access point through the tracheal wall. A concavity in the expandable cuff collects body secretions, and other materials from the oral and nasal cavities and/or gastro-intestinal reflux into the trachea, and the collected secretions are removed by aspiration through a lumen provided in the ventilation device. A one-way valve may be provided in the expandable cuff in order to permit exhalation through the larynx to assist in speech.
