Abstract
An apparatus and method are provided which utilize either the attracting forces of dissimilar pole magnets, or the repelling forces of similar pole magnets, to keep passageways open in living organisms. These passageways might otherwise collapse and close involuntarily due to dysfunction, thus impeding flow of vital gaseous or liquid fluids. Embodiments are described for both permanently implanted and for removable magnets, which may or may not interact with externally attached magnets, thus maximizing the convenience of utilizing this system for the patient. A method of preventing accidental extubation is also described.
