Abstract

A method of treating obstructive sleep apnea according to this disclosure may include: providing an implant comprising a substantially planar central body portion having a top side and a bottom side; at least two adjustable wing portions; and at least two connecting members, each one of the at least two connecting members extending from opposite sides of the central body portion, the each one of the at least two connecting members being configured for flexibly connecting each one of the at least two wing portions at opposite sides to said central body portion; forming a surgical opening to expose a genioglossus muscle; exposing a branch of a hypoglossal nerve for stimulation by the implant at least on one side of the geniouglossus; forming at least one pocket on at least one side of the geniouglossus; such that the pocket dimensions are configured to fit the at least one of the at least two wing portions of the device; inserting an implant device through the surgical opening such that the central body extends over the genioglossus and each one of the wing portions is received in the respective at least one pocket; and securing the implant device to the muscle.

Claims (18)

1. A method of treating obstructive sleep apnea, comprising:

providing an implant device comprising:

a substantially planar central body portion having a top side and a bottom side;

at least two adjustable wing portions; and

at least two connecting members, each one of the at least two connecting members extending from opposite sides of the central body portion, the each one of the at least two connecting members being configured for flexibly connecting each one of the at least two wing portions at opposite sides to said central body portion;

forming a surgical opening to expose a genioglossus muscle;

exposing a branch of a hypoglossal nerve for stimulation by the implant at least on one side of the genioglossus muscle of a patient;

forming at least one pocket on at least one side of the genioglossus muscle such that dimensions of the at least one pocket are configured to fit the at least one of the at least two wing portions of the implant device;

inserting the implant device through the surgical opening such that the central body extends over the genioglossus muscle and each one of the wing portions is received in the respective at least one pocket;

positioning the implant device based on a determination of a relative amount of stimulation potential for both a styloglossus nerve and the hypoglossal nerve by the implant device; and

securing the implant device to the muscle.

2. The method of claim 1 , further comprising determining the relative amount of stimulation potential for both a styloglossus nerve and the hypoglossal nerve by the implant device.

3. The method of claim 2 , wherein determining the relative amount of stimulation potential comprises determining that a stimulation potential for the hypoglossal nerve exceeds a stimulation potential for the styloglossus nerve.

4. The method of claim 1 , further comprising inserting a gauze to keep a mouth of the patient open.

5. The method of claim 1 , further comprising dissecting at least one geniohyoid muscle off of the genioglossus muscle.

6. The method of claim 1 , further comprising dissecting a vein off of the hypoglossal nerve.

7. The method of claim 1 , further comprising holding each of the at least two adjustable wing portions using at least one of non-toothed forceps or fingers.

8. The method of claim 1 , further comprising elevating the genioglossus muscle.
