Devices for diagnosing sleep apnea or other conditions and related systems and methods

A system comprising:

• a sensor device comprising:
• a body configured to be inserted into an airway of a patient;
• and
• multiple sensors mounted in or on the body, the sensors comprising multiple vibrational or acoustic sensors spaced apart along at least part of a length of the body and configured to collect vibrational or acoustic data associated with the airway of the patient at multiple locations along the airway of the patient;
• wherein the sensors in or on the body are configured to be inserted through a mouth or nose of the patient into an esophagus of the patient in order to position the sensors in the airway of the patient;
• and
• a signal analyzer configured to analyze sensor data including the vibrational or acoustic data.

A method comprising:

• placing a patient under sedation;
• inserting a sensor device into an airway of the patient, the sensor device comprising multiple sensors, the sensors comprising multiple vibrational or acoustic sensors spaced apart along at least part of a length of the sensor′ device, the sensors inserted through a mouth or nose of the patient into an esophagus of the patient in order to position the sensors in the airway of the patient;
• collecting sensor data, including vibrational or acoustic data associated with the patient using the sensor device;
• and
• analyzing, using at least one processing unit, the sensor data to determine if the patient suffers from a specified condition affecting the airway of the patient.
