Abstract: The system includes an air flow generator configured to deliver an air flow at a positive therapeutic pressure during the treatment, and an expiratory valve with an open pressure connected to the air flow generator. The open pressure is dependent on the therapeutic pressure from the air flow generator. The expiratory valve further exerts a back pressure upon each exhalation from the patient sufficient to create a pneumatic splint in the patient's respiratory tract. The exhalation from the patient has a first half followed by a second half, and the back pressure is varied such that during the start of the first half, the back pressure is between 0 and 50% of a peak back pressure, and increases to a peak back pressure in the second half.

Abstract: A device for treating a patient suffering from obstructive sleep apnea or snoring can include an expiratory valve connected to a manifold. The expiratory valve can include a body portion including a feedback port configured to be connected to an air flow generator. The expiratory valve can include a plunger at least partially disposed in the body portion. The expiratory valve can include a pressurizing chamber positioned between an end of the plunger and an end of the expiratory valve. The pressurizing chamber can be configured to receive air from the air flow generator through the feedback port.

Abstract: A nasal pillow system for treating sleep apnea is disclosed that may include a nasal pillow. The pillow has a cavity wall that defines a cavity, and two nasal interface structures connected to and extending away from the cavity wall. The nasal interface structures are in fluid communication with cavity. Each nasal interface structure includes a conical nasal interface, a cylindrical trunk structure connected to conical nasal interface and an annular relief pocket connected to the cylindrical truck structure and the cavity wall. The connection between the annular relief pocket and the cavity wall defines substantially a plane, and a first portion of the annular relief pocket extends away from the plane and a second portion extends towards the plane.
