Abstract
A wireless implantable system is provided that is externally powered and comprises of a closed-loop feedback for treating both patients with obstructive and central sleep apnea. A method is provided for treating sleep apnea using an implantable device. The method comprises sensing an inspiration (IN) signal representative of inspiration experienced by a patient from a respiratory surrogate signal and sensing a respiratory effort (RE) signal representative of an amount of effort exerted by the patient during respiration. The method also comprises analyzing the inspiration signal relative to an IN baseline, that corresponds to normal respiratory behavior, to identify an IN indicator, analyzing the RE signal relative to an RE baseline, that corresponds to a normal amount of respiratory exerted by the patient, to identify an RE indicator, declaring a central sleep apnea (CSA) state or an obstructive sleep apnea (OSA) state based on the IN and RE indicators, and delivering at least one of a CSA therapy when the CSA state is declared or an OSA therapy when the OSA state is declared.
