About Sleep Apnea

Obstructive sleep apnea is often caused by a blockage in the airway by the tongue and soft palate during sleep. This can lead to snoring, insufficient air supply to the lungs, and ineffective sleep. Obstructive sleep apnea can contribute to other issues such as hypertension, heart attack, stroke and a higher risk for early death.

The LinguaFlexTM Solution*

The LinguaFlex is a soft and flexible investigational device placed in the underside of the tongue. This simple device prevents the tongue from relaxing backwards as you sleep, so your airway remains open. Once placed, the device is entirely discreet, comfortable, and does not interfere with talking or eating.

A Simple Procedure

The LinguaFlex can be placed in a 10-minute outpatient procedure using light sedation. General anesthesia is not required. If desired, the LinguaFlex can be removed by a doctor at anytime without anesthesia.

*Note: The LinguaFlex is an investigational device only, and has not been cleared by the FDA for use in the U.S.

Our Clinical Study is Now Enrolling

Do you have obstructive sleep apnea? Have you found CPAP machines difficult to use regularly?
You may be eligible to try the LinguaFlex as part of our clinical study!


The LinguaFlex Study is a one-year US study to evaluate the effectiveness of the LinguaFlex for patients with Obstructive Sleep Apnea. Two sites across the U.S. are currently enrolling patients:

  • St Elizabeth’s Medical Center (Boston, MA)
  • West Virginia University (Morgantown, WV)

The LinguaFlex has been tested in a previous clinical trial outside the United States but has not yet received FDA clearance for use in the US. You may or may not experience a reduction in your sleep apnea symptoms and/or a reduction in snoring. Learn more at


All enrolled patients will receive the investigational LinguaFlex device at no cost at the beginning of the study. The device will be placed during a 10-minute procedure under light sedation, and you will go home that same day.

Patients in the study will be asked to take overnight sleep studies or Home Sleep Tests periodically throughout the study, as well as return for approximately 6 follow-up visits. After the study ends at one year, you may choose to keep the device in place or have it removed. If elected, the device can be removed in the doctor’s office without the need for anesthesia.
