Abstract
Methods, systems and probe devices for detecting EMG activity are used in aiding the diagnosis of Obstruction Sleep Apnea (OSA). A probe comprises an elongated member configured with a size and shape for placement adjacent at least one of the soft palate and pharyngeal wall of the patient after insertion of the probe into the patient. The probe includes at least one sensor configured to sense at least EMG activity of muscle layers of at least one of the soft palate and pharyngeal wall and output sensor signals corresponding thereto.
Claims12
A system for assessing a patient, the system comprising:
- a plurality of sensors, each sensor comprising a bipolar electrode, the plurality of sensors being configured for placement on a tissue surface of the patient and configured to produce signals responsive to at least EMG activity of at least one muscle proximate the tissue surface;
- and
- a probe configured with a size and shape to effect placement of at least one sensor of the plurality of sensors proximate at least one of the soft palate, pharyngeal wall and tongue such that the plurality of sensors can detect EMG activity of the at least one muscle, the probe comprising:
- a proximal handle;
- and
- a distal curved end with a convex upper surface and a concave lower surface, and wherein the plurality of sensors are located on the distal curved end;
- wherein at least some of the plurality of sensors are located on the upper convex surface and a greater number of the plurality of sensors is located on the convex upper surface than the concave lower surface.
