Attorney, Agent or FirmInternational ClassA61B 005/02AbstractAn endotracheal tube and inflatable cuff assembly that allows medical instrumentation to be positioned in the trachea. The device remains securely placed in the trachea and allows the passage of gases to the lungs to be controlled. It also provides means for containing various medical instrumentation in a hermetically sealed environment. The device is used during surgery for placement of medical instrumentation, such as heart monitors and electrodes for atrial pacing, inside a hermetically sealed inflatable cuff such that the instrumentation can be appropriately positioned inside the trachea. In another embodiment, no instrumentation is employed so that the inherent limitations of instruments are avoided. | |
