  • Snoring is a typical nocturnal manifestation of Obstructive Sleep Disordered Breathing (OSDB).
  • OSDB encompasses a wide range of psychological effects, including upper airway resistance syndrome, non-obstructive and obstructive sleep apneas and nocturnal Cheyne-Stokes breathing. While snoring is often characterized by partial occlusion of the upper airway passage during sleep, sleep apnea and Cheyne-Stokes breathing is normally characterized by intermittently complete occlusions and/or temporary cessation of breathing.
  • sleep apnea One cause for sleep apnea can be an obstruction of the airway when the muscles of the tongue or uvula relax. Obesity and an abnormal amount of fat in the throat area can contribute to this condition.
  • Another possible cause of apnea is a temporary cessation of the message from the brain that tells the diaphragm to breathe.
  • sleep apnea with each period of breathlessness, which can be as many as twenty or more in an hour, the carbon dioxide level in the blood can rise and fall to extreme levels, with a corresponding periodic decrease in the blood oxygen levels.
  • sleep apnea can cause a patient to develop high blood pressure and other cardiovascular disease, memory problems, weight gain, impotency, and headaches.
  • the sleep apnea is diagnosed and treated sooner during the degenerative cascade, the effects of such physiological problems might be avoided in some cases, or at least the damage might be reduced.
  • Polysomnography is a commonly accepted diagnostic approach to detecting the presence of sleep apnea in an individual. This approach requires the patient to stay overnight in a hospital or sleep clinic for monitoring and observation.
  • a polysomnographic procedure involves tethered connections and monitoring of many parameters while the patient sleeps, typically rendering this procedure quite invasive and uncomfortable for the patient, as well as intensive, site dependent, and costly. In many cases, such an approach is not practical for screening a large number of patients, and thus the majority of patients suffering from OSDB often remain undiagnosed and untreated.
  • a CPAP device employs a face or nasal mask connected to a small air compressor or fan that desirably forces enough air through the nasal passages to maintain the nasal passages open during the night. While such systems can often alleviate some apnea conditions and allow the wearer a good night's sleep, it is also common for such masks to be uncomfortable for the wearer (including restricting the wearer's movements and/or comfortable sleeping positions) and potentially to disrupt the sleep patterns of the user and/or the user's sleeping partners. Moreover, such systems are also often bulky and difficult to transport, typically require a fixed power supply, and are often relatively expensive. Moreover, the long term use of such devices can make the user prone to nasal congestion and infections. In many cases, such devices are not well-tolerated by patients, and compliance rates are low.
  • Another approach to treating breathing disorders of this type is to pace the heart at a faster rate, which can stimulate the sleeper's breathing.
  • a treatment typically requires a surgical procedure to implant a pacemaker or other heartbeat regulating device, a procedure that itself can cause significant
  • Another approach to treating breathing disorders has been to pace or stimulate the muscles of the tongue or uvula, desirably preventing these muscles from relaxing and maintaining the patency of the open airway.
  • Such an approach can reduce constriction of the airway and allow a sleeper to maintain and/or resume their breathing.
  • Such approaches also typically require an implantable nerve or muscle stimulator, which can involve a costly surgical procedure with the attendant risks of surgical complications.

  • apnea is usually assumed to be caused primarily by some obstruction of the air passageways to the lungs. For this reason, treatments have long focused on either reducing the obstructive elements by various means or by forcing air into the lungs to overcome the obstruction. Many devices have emerged to alter the air passageways in attempts to create an unobstructed path for breathing. Often, these devices and methods have failed to alleviate the problem or been too obtrusive to sleep themselves and fallen out of favor. Also, such devices fail to treat central sleep apnea that results from neurological dysfunction rather than airway obstruction. Such dysfunction occurs in many sleep apnea patients as well as heart failure patients suffering from Cheyne-Stokes breathing.
  • SIDS Sudden Infant Death Syndrome
  • CPAP has been utilized very successfully in many patients to force air into the lungs even with some airway obstruction, but suffers from a high incidence of noncompliance.

  • this activity will reduce one or more outer dimensions of the distal portion of the device, thereby facilitating placement of the device 10 into the ear canal and other ear structures of the user (with the distal portion of the device sliding at least partially within the ear canal 30 of the user).
