Abstract
A method for treating upper respiratory obstructions in a patient by electrical stimulation of muscles of the upper airway including surgically implanting a impedance sensing circuit into the patient such that the impedance sensor is capable of providing a signal characteristic of transthoracic impedance in the patient. The implanted impedance sensing circuit allows the inspiratory phase of the patient's respiratory cycle to be identified and electrical stimulation to be reliably applied during the inspiration phase.
