| abstract |
A repositionable medical tube, such as an endotracheal tube, a nasogastric tube, or a nasojejunal tube, having an inflatable cuff with at least one divot region therein, the divot region having an outer diameter sufficiently smaller than an outer diameter of both a proximate cuff region and of a distal cuff region as to produce a discernibly-distinct ultrasonic image when scanned by an ultrasound sensor. The medical tube may be further provided with an ultrasonically-detectable coil or one or more ultrasonically-detectable markers having an identifiable geometric shape when the marker is visible using an ultrasonic probe. |
