The objective of the study is to assess the effectiveness of the Aspire Medical Advance System in obstructive sleep apnea by demonstrating a statistically significant mean reduction in the apnea-hypopnea index (AHI) from baseline to 6 months, measured by polysomnography (PSG).
Obstructive sleep apnea (OSA) is a major health problem in the United States and can result in excessive daytime sleepiness and cardiovascular problems. The primary treatment for OSA today is continuous positive airway pressure (CPAP). Many patients however are unable to tolerate sleeping with a CPAP machine. Surgery is one of the main treatment options available today to these CPAP-intolerant patients. However, current methods of sleep surgery are painful, morbid, and/or lack decent effectiveness.
This trial will measure the effectiveness of the Advance System, an implantable medical device to treat OSA. In the trial, patients who meet the study entry criteria receive a baseline sleep study (PSG). The Advance System is then implanted and 6 months after implantation, another PSG is performed. The trial will compare the baseline and the 6 month apnea-hypopnea indices

This is a prospective, multi-center, single arm, feasibility study to evaluate the safety and effectiveness of the ReVENT Sleep Apnea System for the treatment of Obstructive Sleep Apnea.
The primary objective of this study is to confirm the safety and clinical effectiveness of the Genio™ system, used according to its instructions for use, in moderate to severe Obstructiv...
Obstructive sleep apnea is the most common type of sleep apnea, which is caused by complete or partial obstructions of the upper airway. Nasal obstruction is also considered as one of the independent ...
Obstructive sleep apnea is an underdiagnosed sleep-related breathing disorder affecting millions of people. Recurrent episodes of apnea/hypopnea result in intermittent hypoxia leading to oxidative str...
Obstructive sleep apnea (OSA) is a common sleep disorder; however, most patients are undiagnosed and untreated because it is difficult for patients themselves to notice OSA in daily living. Polysomnog...
Obstructive sleep apnea (OSA) and systemic hypertension (SH) are common and interrelated diseases. It is estimated that approximately 75% of treatment-resistant hypertension cases have an underlying O...
To elucidate current knowledge on the potential association and causality between sleep bruxism (SB) and obstructive sleep apnea (OSA) using full-night polysomnography.
A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)
Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)
HYPOVENTILATION syndrome in very obese persons with excessive ADIPOSE TISSUE around the ABDOMEN and DIAPHRAGM. It is characterized by diminished to absent ventilatory chemoresponsiveness; chronic HYPOXIA; HYPERCAPNIA; POLYCYTHEMIA; and long periods of sleep during day and night (HYPERSOMNOLENCE). It is a condition often related to OBSTRUCTIVE SLEEP APNEA but can occur separately.
Sleep disorders disrupt sleep during the night, or cause sleepiness during the day, caused by physiological or psychological factors. The common ones include snoring and sleep apnea, insomnia, parasomnias, sleep paralysis, restless legs syndrome, circa...
