Bronchial blocker endotracheal apparatus
First Claim
1. An endotracheal apparatus for insertion through the mouth and into the trachea of a patient for ventilating one lung and blocking the other lung comprising:
- a first elongated flexible tube having an external wall portion, a proximal end and a distal end, the distal end being positioned in the trachea when in use and adapted for ventilating air;
a second elongated flexible tube, separate from the first tube, having a proximal end and a distal end, an external wall portion of the second elongated flexible tube being closely joined in a side-by-side relation to said external wall portion of the first elongated flexible tube, the second elongated flexible tube for receiving an endobrochial blocker;
a first inflatable and deflatable cuff extending about the first and second elongated flexible tubes toward the distal ends of the first and second tubes, the first inflatable and deflatable cuff being positioned and operable when inflated to engage the trachea;
an endobronchial blocker comprising an elongated catheter having a proximal end and a distal end, being slidably receivable in the second elongated flexible tube, the elongated catheter having an inflatable and deflatable cuff disposed about the distal end of the elongated catheter; and
,an air passage defined in a wall of the first elongated flexible tube and terminating within the first inflatable and deflatable cuff.

Abstract
An endotracheal tube (12) ventilates air from the lungs of a patient when inserted into the trachea. A second flexible tube (14) is closely joined to the endotracheal tube (12) in a side-by-side relation. The second flexible tube (14) slidably receives a catheter or endobronchial blocker (16) which has an inflatable cuff (32). The cuff (32) is maneuvered into the right or left bronchus of the patient by sliding and rotating the catheter or bronchial blocker (16) into a position to occlude the selected bronchus. A tracheal cuff (18) is disposed around the endotracheal tube (12) and the second flexible tube (14). When inflated, the tracheal cuff (18) engages the walls of the trachea to reduce passage of air and to secure the position of the endotracheal tube (12).

10. An endotracheal apparatus for insertion through the mouth and into the trachea of a patient for ventilating at least one lung comprising:
-
a first flexible tube having a sufficient length to extend from the mouth to a position near the carina of the trachea, the first flexible tube being adapted to communicate air; a second flexible tube separate from the first flexible tube and having a length substantially equal to he length of the first flexible tube, the second flexible tube having a portion of an outer surface wall closely joined in a side-by-side relation with a portion of an outer surface wall of the first flexible tube, the second flexible tube being adapted to slidably receive an elongated instrument; and, an elongated instrument having a bronchial blocking cuff sealed to a distal end of the elongated instrument, the elongated instrument being slidably received into the second flexible tube such that the distal end extends beyond a distal end of the second flexible tube and into the selected bronchus. - View Dependent Claims (11, 12, 13, 14, 15, 20)

16. A method of using an endotracheal apparatus for ventilating one lung and blocking the other lung of a patient comprising the steps of:
-
providing separate first and second flexible tubes closely joined in a side-by-side relation along their external walls, each of the first and second flexible tubes having a length sufficient to extend from the patient'"'"'s mouth and into the patient'"'"'s trachea, the second flexible tube being configured to receive an elongated catheter having a bronchial blocking cuff; inserting the first and second flexible tubes through the mouth and into the trachea with a distal end of the first and second flexible tubes being at a position near the carina; providing an elongated catheter having a bronchial blocking cuff disposed toward a distal end of the catheter; inserting the distal end of the elongated catheter into the second flexible tube and maneuvering the bronchial blocking cuff into a bronchus; and
,inflating the bronchial blocking cuff to occlude the bronchus. - View Dependent Claims (17, 18)
