  • Patent number: 6792948
    Abstract: The disclosed laryngeal mask airway device includes an inflatable cuff and an airway tube. The inflatable cuff defines a central opening at least when inflated. The cuff is insertable through a mouth of a patient to an inserted location within the patient. The cuff surrounds a glottic opening of the patient when the cuff is inflated and at the inserted location. The airway tube extends from a proximal end to a distal end. The airway tube defines an internal passage, an anterior portion, a posterior portion, a left portion, and a right portion. An airway passage extends from the proximal end of the tube through the internal passage to the glottic opening when the cuff is inflated and at the inserted location. The anterior portion is characterized by a thinner wall thickness than the left and right portions. The posterior portion is characterized by a thinner wall thickness than the left and right portions.

  • Patent number: 6766801
    Abstract: An aerosol delivery system includes an endotracheal tube with a sub-port having a sufficient diameter to permit the passage of a sub-port tube therethrough. The sub-port tube passes within the interior of the endotracheal tube via the sub-port and includes a passageway that terminates in an atomizer nozzle at the distal end of the sub-port tube. The atomizer nozzle and the endotracheal tube are integrally connected to one another at a distal end base outlet of the endotracheal tube. A delivery conduit having an atomizer connector at its distal end is adapted to be connected to a canister for delivering fluid under pressure. The delivery conduit has a sufficient length to pass within the sub-port tube to lockingly engage the atomizer nozzle atomizer, whereby fluid delivered under pressure from the canister flows to the atomizer nozzle causing an aerosol mist to be dispensed outwardly from the base outlet of the endotracheal tube.
