Endotracheal Lung Suction System for Selective Lung Drainage
Summary
The USPTO published patent application US20260097175A1 assigned to Roberts Innovations, LLC covering an endotracheal lung suction system for selective lung drainage. The system includes an endotracheal tube with an implantation balloon, a suction assembly with proximal valve, and an inner suction catheter with an inflatable securing device. The invention enables selective drainage of user-selected lungs through a dual-lumen catheter design.
What changed
The USPTO published patent application US20260097175A1 for an endotracheal lung suction system invented by John R. Roberts and Timothy D. Roberts of Roberts Innovations, LLC. The system comprises an endotracheal tube with an implantation balloon, a suction assembly with proximal valve and distal connector, and an inner suction catheter featuring an inflatable hollow securing device. The catheter includes a main lumen and a parallel catheter-securing inflation lumen.
Manufacturers of medical suction and endotracheal devices should monitor this patent for potential licensing implications or design considerations. The dual-lumen catheter design with selective lung drainage capability represents a specialized area of respiratory care technology.

Abstract
An endotracheal lung suction system includes an endotracheal tube defining a tube lumen, a suction assembly, and an inner suction catheter. The endotracheal tube comprises an inflation connector and an implantation balloon adjacent the distal tube end and fluidically connected to the inflation connection and through which the balloon inflates. The suction assembly comprises a proximal valve and a distal endotracheal tube connector fluidically connected to an interior of the tube lumen. The inner suction catheter passes through and slides within the suction assembly, the endotracheal tube connector, and through the tube lumen to extend slidably out from and back into the distal tube end. The inner suction catheter comprises a distal, inflatable, hollow, inner-suction-catheter securing device and a catheter body defining a main lumen extending through the inner suction catheter and a catheter-securing inflation lumen extending through the inner suction catheter parallel to the main lumen.
