Abstract: Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

Abstract: A battery management circuit provides an implantable medical device with power management that allows safe and efficient use of a rechargeable battery. Various ways of monitoring the energy level of the rechargeable battery and controlling the battery recharging process for user convenience and safety are provided.

Abstract: An electrical neuro-stimulator which operates using pulse generators for providing a master frequency, a carrier frequency, a first modulation frequency and a second modulation frequency. The pulse width and pulse rate are adjustable, and a pair of multivibrators produces a pulse train output with an adjustable number of impulses by adjustment of the carrier frequency, which also increases the average applied power and the penetration factor. The master and carrier oscillators of the pulse generator operate asynchronously, and a digital mixer is provided for combination of these frequencies with a slightly random appearance, thus avoiding accommodation or adaptation while maintaining a constant energy at any frequency. The first modulation frequency provides a triangular form of amplitude modulation of the pulse train waveform envelope. A 180 degree shift in this waveform is provided by a time lag introduced on the second channel, such that accommodation of the nerves is avoided.
