Lung-Selectable Endotracheal Aspiration System and Methods for Draining a User-Selected Lung

An endotracheal lung suction system, comprising:

• an endotracheal tube defining a tube lumen and comprising:
• a distal tube end defining a distal opening of the tube lumen;
• a proximal tube end defining a proximal opening of the tube lumen;
• an inflation connector;
• and
• an implantation balloon fluidically connected to the inflation connection and through which the implantation balloon is inflated, the implantation balloon disposed adjacent the distal tube end;
• a suction assembly comprising:
• a distal endotracheal tube connector at the proximal tube end and defining a tube opening fluidically connected to an interior of the tube lumen through the distal opening of the tube lumen;
• and
• a proximal valve defining a proximal valve catheter opening fluidically connected through the suction assembly to the interior of the tube lumen;
• and
• an inner suction catheter shaped and sized to pass through and slide within the suction assembly from proximal of the proximal valve, distally through the tube opening of the endotracheal tube connector, and through the tube lumen to extend slidably out from and back into the proximal opening of the distal tube end, the inner suction catheter comprising:
• a proximal portion comprising a proximal catheter end;
• a distal portion comprising a distal catheter end;
• an inflatable, hollow, inner-suction-catheter securing device at the distal portion and comprising an inflation interior defining an inflation interior opening;
• and
• a catheter body defining:
• a main lumen extending through the inner suction catheter from the proximal catheter end to the distal catheter end;
• and
• a catheter-securing inflation lumen extending through the inner suction catheter parallel to the main lumen from the proximal portion distally to the inflation interior opening.
