  • Devices, systems, and methods using magnetic force systems in or on tissue
    Patent number: 7721740
    Abstract: Systems and methods include magnetic structures for placement in or on tissues in an airway. The magnetic structures carry sources of magnetism, which generate magnetic fields having directions. The magnetic fields interact to provide magnetic forces that provide a desired therapeutic effect, e.g., maintaining separation between the soft palate and/or tongue and the posterior pharyngeal wall. The systems and methods size and configure the directions of the magnetic fields to provide stability, which makes possible the achievement of the desired therapeutic effect in a straightforward and elegant manner.
