Abstract
A method and system for an endotracheal tube or tracheostomy a tube formed with a hole, a cuff connected to the tube and formed around the hole, and a skirt connected to the tube above the cuff and draped over the cuff. A coating of a hydrophobic, lipophobic, and oleophobic substance can be disposed on the interior and exterior surface of the tube, the cuff, and the skirt. A stylet and siring may be used to secure the skirt during insertion in a detachable fashion. The string is retractable on withdrawal of the stylet.
Claims20
A system comprising:
- a tube formed with a hole;
- a cuff connected to said tube and sealed around said hole;
- a skirt connected to said tube above said cuff and draped over said cuff;
- and
- a plurality of skirt struts formed in said skirt, each of said plurality of skirt struts comprising a wedge shape with a wider portion of said wedge shape at a bottom of said skirt;
- wherein airflow is provided through said tube and through said hole to inflate said cuff during patient inhalation.

A tracheostomy system comprising:
- a cuff connected to an endotracheal tube;
- an inflation conduit configured to deliver gas to said cuff;
- a skirt connected to said endotracheal tube above said cuff and draped over said cuff wherein inflation of said cuff spreads said skirt and said skirt is configured to be sealed against the patient's trachea with a patient expiration, wherein said skirt and said cuff are located on said endotracheal tube for positioning in a subglottic region of said trachea;
- a plurality of skirt struts formed in said skirt, each of said plurality of skirt struts comprising a wedge shape with a wider portion of said wedge shape at a bottom of said skirt;
- a coating comprising a hydrophobic, lipophobic, and oleophobic substance formed on an interior surface and an exterior surface of said endotracheal tube, said cuff, and said skirt, respectively;
- a Murphy's Eye formed at a distal end of said endotracheal tube;
- a stylet;
- and
- a string connected to said stylet, said string configured to anchor said skirt to said endotracheal tube, wherein said string is configured to traverse said Murphy's Eye.

A ventilation method comprising:
- inserting a device comprising a tube formed with a hole, a cuff connected to said tube and sealed around said hole, and a skirt connected to said tube above said cuff and draped over said cuff, wherein a plurality of skirt struts are formed in said skirt, each of said plurality of skirt struts comprising a wedge shape with a wider portion of said wedge shape at a bottom of said skirt, into a trachea of a patient;
- inflating said cuff with an airflow through said tube and via said hole during said patient's inhalation;
- deploying said skirt via inflation of said cuff;
- and
- sealing said skirt with positive end expiratory pressure from said patient's exhalation.
