12820325, 12820315, 12820312, 12820024, 12820014

Abstract:

The present invention includes a transient method of delivering a biological agent in a breathable liquid to a lung of a patient. The present invention includes a steady state method of delivering a biological agent in a breathable liquid to a lung of a patient. The steps of both the transient delivery method and the steady state delivery method can be controlled by a servo-control unit. A supplementary biological agent delivery step can be performed in both the transient method of delivering a biological agent and the steady state method of delivering a biological agent.

US Classification:

602 19, 5630, 600587

Abstract:

A thoracic stabilizer for limiting anterior chest wall collapse includes a platform supporting a patient and a pair of lateral supports contacting opposite sides of the patient's chest wall and applying force to limit collapse of the chest wall. The force applied by the lateral supports is varied depending on the force applied to the platform by the patient. The stabilizer includes a retractometer measuring the collapse of the chest wall. According to one embodiment, the stabilizer includes a controller that varies the force applied to the chest wall in closed-loop fashion based on the chest wall collapse measured by the retractometer using an algorithm of the controller. According to one embodiment, the stabilizer includes motors moving the lateral supports. According to another embodiment, the stabilizer includes a hydraulic system and the lateral supports include expandable fluid-filled members.

US Classification:

12820714, 12820026, 12820418, 12820715

Abstract:

A system for unilateral lung ventilation includes an endotracheal tube and a blocking device for blocking the bronchus of a non-ventilated lung to prevent a ventilation medium from entering the lung. The blocking device includes an inflatable member supported by a catheter having an inflation lumen for inflating the inflatable member. The catheter includes at least one lung treatment lumen for delivering a therapeutic agent to the non-ventilated lung. An inner channel within the main channel and a side branch provide a guideway for the blocking device within the tube. A valve may be included to close the side branch when the blocking device is removed from the inner channel for parallel flow of ventilating gas in the main and inner channels. A method of using the system provides for ventilation/perfusion (V/Q) matching by respectively delivering cooled air and nitric oxide to the non-ventilated and ventilated lungs.

International Classification:

A61M 16/00
A61M 15/00

US Classification:

12820325, 12820315

Abstract:

An open-circuit liquid ventilation system includes a reservoir containing a breathable liquid, a patient interface receiving breathable liquid from the reservoir, a pump directing breathable liquid from the reservoir to the patient, a controller for the pump, and a tank for storing used breathable liquid. The system may be passive regarding expired liquid. Alternatively, the system may be active and include a bypass line connected to the pump such that used breathable liquid is drawn from the patient. The patient interface may be adapted to interface a gas ventilation system to facilitate a rapid conversion from gas to liquid ventilation. The system may include sensors monitoring pressure and volume parameters and may include an output displaying information including schematics and real time tracings regarding a ventilation procedure.
