Abstract

An endotracheal tube airway patency system and method are provided. The system includes an endotracheal tube having a tube body having a proximal end, a distal end, an inner surface, a distal opening disposed at the distal end of the tube body, a proximal opening disposed at the proximal end of the tube body, and an airflow-effacing surface disposed within the tube body. The airflow-effacing surface includes a telescoping inner sleeve configured to be removed from the endotracheal tube body. The system further includes a tool for removal of the telescoping internal sleeve from the endotracheal tube body. The tool includes an elongated body having a proximal end and a distal end; a handle located at the proximal end of the elongated body; and at least one extension member disposed at the distal end of the elongated body. The at least one extension member is configured to couple to the telescoping internal sleeve for removal of the telescoping internal sleeve from the endotracheal tube body.

Claims (23)

1. A tool for removal of a telescoping internal sleeve from

an endotracheal tube, the tool comprising:

an elongated body having a proximal end and a distal end;

a handle located at the proximal end of the elongated body; and

at least one extension member disposed at the distal end of the elongated body, the at least one extension member comprising a coupling portion at a distal end of the at least one extension member, the coupling portion comprising a magnetic attachment configured to couple to a magnetic receiving tab of the telescoping internal sleeve of the endotracheal tube for removal of the telescoping internal sleeve from the endotracheal tube.

2. The tool of claim 1 , wherein the at least one extension member comprises three extension members.

3. The tool of claim 1 , wherein the handle comprises a dial configured to rotate, wherein rotation of the dial in a first direction causes the at least one extension member to be moved into an open position and wherein rotation of the dial in a second direction causes the at least one extension member to be moved into a closed position.

4. The tool of claim 3 , wherein in the open position, the at least one extension member is configured to initiate coupling to the telescoping internal sleeve.

5. The tool of claim 3 , wherein when the dial is rotated from the open position to the closed position, the at least one extension member is configured to retain the telescoping internal sleeve to retract the telescoping internal sleeve from the endotracheal tube.

6. The tool of claim 1 , wherein the at least one extension member comprises a hook extending from a distal end of the at least one extension member.

7. The tool of claim 6 , further comprising a protrusion extending from the distal end of the at least one extension member, wherein the hook extends from the protrusion.

8. The tool of claim 6 , wherein the hook is configured to couple to a receiving tab of the telescoping internal sleeve.

9. The tool of claim 6 , wherein the hook comprises a magnetic hook.

10. An endotracheal tube airway patency system comprising:

an endotracheal tube comprising a tube body having a proximal end, a distal end, an inner surface, a distal opening disposed at the distal end of the tube body, a proximal opening disposed at the proximal end of the tube body, and an airflow-effacing surface disposed within the tube body, wherein the airflow-effacing surface comprises a telescoping internal sleeve configured to be removed from the endotracheal tube body, the telescoping internal sleeve having a magnetic receiving tab; and

a tool for removal of a telescoping internal sleeve from the endotracheal tube body, the tool comprising:

an elongated body having a proximal end and a distal end;

a handle located at the proximal end of the elongated body; and

at least one extension member disposed at the distal end of the elongated body, the at least one extension member comprising a coupling portion at a distal end of the at least one extension member, the coupling portion comprising a magnetic attachment configured to couple to the magnetic receiving tab of the telescoping internal sleeve of the endotracheal tube for removal of the telescoping internal sleeve from the endotracheal tube.

11. The system of claim 10 , wherein the telescoping internal sleeve comprises one or more layers which are independently removable from the endotracheal tube body.

12. The system of claim 10 , wherein the telescoping internal sleeve is collapsible.

13. The system of claim 10 , wherein the telescoping internal sleeve is disposed adjacent to or in contact with the inner surface of the endotracheal tube body to maintain patency of the endotracheal tube.

14. The system of claim 10 , wherein removal of the telescoping internal sleeve exposes a sterile surface on the inner surface of the endotracheal tube body.
