Problems solved by technology

Although the efficacy of this technique has been demonstrated, potential difficulties arise due to: MRI compatibility issues, long wires, need for a lead from the thoracentesis to the submandibular region, and subcutaneous implantation under the subclavian skin Embedded batteries and processors in tissue

Embodiment

[0071] With severe OSA (AHI 73, minimum O 2 Saturation 79%) in a 55-year-old female with intolerance to nasal CPAP. She can only tolerate 1-2 hours of CPAP use per night and suffers from excessive daytime fatigue as a result. Other than that, her overall health is excellent.

[0072] Examination revealed a slender lady with mildly recessive upper and lower jaws and a good nasal airway. She has a Friedman grade 2 tongue position and grade 2 tonsils. Endoscopy revealed AP narrowing of the retropalatal airway, and to a lesser degree narrowing of the retrolingual airway. Lingual tonsil hypertrophy was absent. Jaw extension improves airway at all levels.

[0073] In 2016, she underwent revised UPPP, transpalatal advancement pharyngoplasty and radiofrequency tongue channelling.

[0074] She had an uneventful recovery, and her 3-month post-surgery PSG showed an AHI of 27 (73 pre-surgery), and a nadir Sa02 of 92%. However, her supine AHI was unchanged at 77.8. Although her Epw...

Abstract

A method of treating obstructive sleep apnea according to this disclosure may comprise: 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 of the at least two connecting members extending from opposite sides of the central body portion, each of the at least two connecting members configured to flexibly connect each of the at least two wing portions to the central body portion on the opposite sides; forming a surgical opening to expose the genioglossus muscle; exposing a hypoglossal nerve branch at least on one side of the genioglossus for stimulation by an implant; forming at least one pocket on at least one side of the genioglossus; such that the pocket is dimensioned to mount at least one of the at least two wing portions of the device; inserting the implant device through the surgical opening such that the central body extends over the genioglossus and each of the wing portions is received in a respective at least one pocket; and securing the implant device to the muscle.

Description

technical field [0001] The disclosed subject matter relates to methods and procedures for placing and securing surgical implants for the treatment of sleeping disorders, and in particular sleep apnea. Background technique [0002] Obstructive sleep apnea is a common and heterogenous disorder characterized by repeated partial or complete obstruction of the pharyngeal airway during sleep. In most patients, there is an anatomical predisposition (predisposition) for the disorder. Complicating this may be abnormalities in ventilatory control (eg high loop gain), and elevated arousal threshold during sleep. Pharyngeal muscles respond to input from mechanoreceptors in the airway and blood oxygen and CO 2 respond to changes in levels. The genioglossus is the major dilator of the pharyngeal airway. Inability of upper airway dilator muscles to adequately respond to airflow restriction and / or CO 2 with O 2 Responding to changes in levels can lead to obstructive OSA. [0003] Hyp...
