Abstract
An inflatable balloon cuff may be adapted to seal a patient's trachea when associated with an endotracheal tube. These cuffs may include features that facilitate detection or visualization of the cuff, for example with ultrasound devices, to ensure proper placement of the cuff and the tube. Such surface features may include particular types of materials or shaped or protruding features that may be detected in the environment of the trachea.
Claims19
A tracheal tube comprising:
- a conduit;
- and
- a balloon cuff associated with the conduit, wherein the balloon cuff comprises an inflatable region and wherein a portion of a balloon wall of the inflatable region is configured to contact a trachea when inflated comprises a surface feature configured to be detected by an ultrasound transducer located outside a patient's body, wherein the surface feature comprises an anti-reflective material disposed on the balloon wall.
A medical device comprising:
- a conduit;
- a first balloon cuff associated with the conduit;
- and
- a second balloon cuff associated with the conduit, wherein the second balloon cuff comprises an inflatable region and wherein a portion of a balloon wall of the inflatable region capable of contacting a trachea when inflated comprises a surface feature capable of being detected by an ultrasound transducer located outside a patient's body.
