  • Nasal intubation apparatus
    Patent number: 5842973
    Abstract: A nasal intubation apparatus comprises a curved rigid body having a distal end and a proximal end joined by a curved section which approximates the curvature of the transition of the normal human nasopharynx to the oropharynx. The body has provided in it fiberoptic viewing and illumination channels. A working channel is provided to permit use of a flexible guide member to act as a guide for positioning of an endotracheal tube fitted over the intubation apparatus body. A controllable tip section at the distal end of the body is provided.

  • Oropharyngeal stent with laryngeal aditus shield and nasal airway with laryngeal aditus shield
    Patent number: 5791341
    Abstract: An oropharyngeal stent and aditus shield comprises a curved flexible tubular body containing a central airway with a first inflatable cuff surrounding a portion of the body, and a laryngeal aditus shield comprising a generally triangular second inflatable cuff located at the distal end of the body. In a nasal airway embodiment, the airway comprises a body with a laryngeal aditus shield.

  • Multifunctional intubating guide stylet and laryngoscope
    Patent number: 5665052
    Abstract: A multifunctional intubating stylet and laryngoscope, and a method of intubating a patient, comprise a laryngoscope body, and a hollow tubular intubating stylet affixed to and extending generally parallel to the laryngoscope body. An endotracheal tube is mounted on the exterior of the stylet. A guide member is passed through the interior of the stylet and advanced through the patient's vocal cords into the trachea. The endotracheal tube is then advanced along the guide member until it is established in a desired location in the patient's trachea to permit ventilation of the patient.

  • Controlled targeting laryngoscope
    Patent number: 5643221
    Abstract: A laryngoscope having a rigid shaft, an image bundle, and a movable distal end member connected to the distal end of the shaft. The distal end of the image bundle is located in the distal end member such that the field of view can be changed by moving the distal end member without having to move the rigid shaft. The shaft and distal end member can also have a channel for passing a placement device therethrough such that the positioning of an object at a target area can be controlled by moving the distal end member without having to move the rigid shaft.
