Cuffed nasal airway and anesthetic wand system
First Claim
1. A cuffed nasal airway comprising:
- a flexible tube having a first end and a second end, a length, and an opening extending from the first end to the second end, the length of the flexible tube being such that upon insertion into a nasal cavity of a patient, the second end is in substantial alignment with a soft palate and a lateral pharyngeal wall of a patient;
an inflatable cuff positioned at the second end of the tube;
means for inflating the cuff after alignment of the flexible tube in a patient to, in turn, provide a seal with the soft palate, the lateral pharyngeal wall, and a tongue of a patient.

Abstract
A nasal airway system.comprising a cuffed nasal airway and a nasal wand. The cuffed nasal airway includes a flexible tube, an inflatable cuff and a member for inflating the cuff. The flexible tube includes a first end and a second end, a length, and an opening extending from the first end to the second end. The length of the tube is such that upon insertion into a nasal cavity of a patient, the second end is in substantial alignment with a soft palate and a lateral pharyngeal wall of a patient. The inflatable cuff is associated with the second end of the tube. The inflating member inflates the cuff after alignment of the flexible tube in a patient to, in turn, provide a seal with the soft palate, the lateral pharyngeal wall, and the base of the tongue of the patient. The nasal wand includes a housing, a flexible wand and a fluid delivery member. The housing includes an inner chamber with a fluid. The flexible wand is substantially soft and substantially bendable, and, includes a plurality of openings along the length thereof. The fluid delivery member capable of delivering the fluid through the openings in the wand.
