Evaluation of the Effects of Hypoglossal Nerve Stimulation in Humans With Obstructive Sleep Apnea

This proof-of-concept study is being performed to evaluate whether the hypoglossal nerve can be stimulated using a small series of electrodes placed surgically via a percutaneous approach. Minimally invasive off the shelf medical devices will be used and observation of the characteristic physiological responses to stimulation of the HGN, will be assessed.

Treatment and study plan

Hypoglossal Nerve Stimulation

Device

Device stimulation of the hypoglossal nerve

Primary outcomes

  1. Target identification and access outcomes

    Time frame: Day 0

    Identification of and access to the target stimulation location aligned with the medial branch of the Hypoglossal Nerve

  2. Tongue protrusion outcomes

    Time frame: Day 0

    Visual verification of protrusion of the tongue during stimulation at the target stimulation location with a representative electrode array.

  3. Characterization of lead placement outcomes

    Time frame: Day 0

    Spatial characterization of the orientation of the electrode array and lead body to the target stimulation location considering suitable chronic anchoring locations.

  4. Lead placement and removal outcomes

    Time frame: Day 0

    To demonstrate the ability to safely place and remove the electrode array, per protocol instructions.

  5. Safety outcomes

    Time frame: Day 30

    To evaluate and report all observed adverse events, serious adverse events, unanticipated adverse events and adverse device effects observed during the study
