1. A method of treating an upper airway tissue collapse condition of a patient, comprising:
- Implanting at least one tissue engagement member in the patient'"'"'s upper airway tissue to improve a coupling between the patient'"'"'s genioglossus muscle and a portion of the patient'"'"'s upper airway tissue; and
providing a stimulation therapy that delivers an electrical stimulation to a hypoglossal nerve of the patient to cause an advancement of the patient'"'"'s genioglossus muscle and/or an anterior movement of the patient'"'"'s tongue, the stimulation therapy having an efficacy in the treatment of the upper airway tissue collapse condition, wherein the at least one tissue engagement member improves the efficacy of the stimulation therapy.

Abstract
Devices and methods for improving the coupling between the soft palate and the genioglossus. This may be accomplished, for example, but shortening or stiffening the palatoglossal arch. Improved coupling between the soft palate and the genioglossus may be beneficial to a patient suffering from obstructive sleep apnea (OSA) as a stand-alone procedure, or in combination procedures and devices that cause anterior displacement of the tongue such as hypoglossal nerve stimulation, genioglossus advancement surgery, mandibular advancement surgery, mandibular advancement (oral) appliances, etc.

9. A method of treating an upper airway tissue collapse condition of a patient, comprising:
-
modifying a first length of the patient'"'"'s palatoglossus to a shortened second length by implanting at least one tissue engagement member in a first portion of tissue disposed at the patient'"'"'s palatoglossus to improve a coupling between a movement of the patient'"'"'s tongue and a corresponding movement of a second portion of tissue disposed in the couplings upper airway; disposing a stimulation device configured to electrically stimulate the patient to move the patient'"'"'s tongue anteriorly, the patient'"'"'s tongue being coupled to the second portion of tissue via the first portion of tissue; and maintaining the corresponding movement of the second portion of tissue when delivering an electrical stimulation. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method of treating an upper airway tissue collapse condition of a patient, comprising:
-
Implanting at least one tissue engagement member in the patient'"'"'s upper airway tissue to tighten the patient'"'"'s upper airway from a first condition of the patient'"'"'s upper airway tissue to a second condition of the patient'"'"'s upper airway tissue that has a greater stiffness than the first condition. the patient'"'"'s upper airway issue in the second condition conveying anterior movement of the patient'"'"'s tongue to maintain a patency of the patient'"'"'s upper airway; and disposing a stimulation device configured for delivering an electrical stimulation to a nerve innervating a tongue protruder muscle of the patient to cause an anterior movement of the patient'"'"'s tongue, wherein the at least one tissue engagement member improves an efficacy of the electrical stimulation. - View Dependent Claims (21, 22, 23, 24)

25. A method of treating an upper airway condition of a patient, the method comprising:
- implanting a first device in the upper airway of the patient, the first device having a first end secured to a first portion of upper airway tissue coupled to the tongue of the patient and an opposing second end secured to a second portion of upper airway tissue coupled to at least one of the patient'"'"'s soft palate, palatopharyngeus, and palatoglossus; and
implanting a second device in the patient, the second device disposed to deliver an electrical stimulation signal to the patient'"'"'s hypoglossal nerve to move the second portion of upper airway tissue via the first device.
- implanting a first device in the upper airway of the patient, the first device having a first end secured to a first portion of upper airway tissue coupled to the tongue of the patient and an opposing second end secured to a second portion of upper airway tissue coupled to at least one of the patient'"'"'s soft palate, palatopharyngeus, and palatoglossus; and

26. A method of treating an upper airway condition of a patient, the method comprising:
- implanting first and second devices in the patient'"'"'s neck to treat a collapsed portion of the patient'"'"'s upper airway, the second device being a stimulation delivery device disposed and configured to deliver an electrical stimulation signal to cause a movement of the patient'"'"'s tongue, the first device disposed and configured to convey the stimulated movement of the patient'"'"'s tongue to the collapsed portion of the patient'"'"'s upper airway, wherein to open the collapsed portion of the patient'"'"'s upper airway; and
maintaining the delivery of the stimulation signal during an inspiration cycle of the patient.
- implanting first and second devices in the patient'"'"'s neck to treat a collapsed portion of the patient'"'"'s upper airway, the second device being a stimulation delivery device disposed and configured to deliver an electrical stimulation signal to cause a movement of the patient'"'"'s tongue, the first device disposed and configured to convey the stimulated movement of the patient'"'"'s tongue to the collapsed portion of the patient'"'"'s upper airway, wherein to open the collapsed portion of the patient'"'"'s upper airway; and
