SYSTEM AND METHOD FOR PREVENTING
CLOSURE OF PASSAGEWAYS
This application is a divisional of Canadian patent application Serial No. 2,500,855 filed internationally on October 6, 2003 and entered nationally on April 1, 2005.
BACKGROUND OF THE INVENTION
Field of the Invention Embodiments of the present invention generally relate to prevention of abnormal breathing sounds (e.g., snoring), adverse consequences, illness or death in persons due to partial or complete blockage of the upper airway.
Description of the Related Art A common and potentially serious disorder in humans involves involuntary closure of the airway during sleep. This disorder is known as "sleep-disordered breathing" or "obstructive sleep apnea" (OSA). In persons with OSA, there is involuntary closure or reduction in caliber of a portion of the airway that connects the atmosphere to the lungs. The upper portion of the airway (the "upper airway") consists of two passageways, the nasal airway and the oral airway.
These two passageways merge to become a single passageway. Portions of the upper airway just behind the tongue are known as the soft palate, the pharynx, the hypopharynx, etc.
In persons affected by OSA, closure, reduction in patency or increased airflow resistance of the upper airway occurs during sleep, due to a combination of physiological changes associated with sleep (including relaxation of muscles) and the anatomy of the upper airway (which is generally smaller or more crowded than in normal individuals). In persons prone to sleep apnea, a portion or portions of the muscular walls of the upper airway may become narrow or collapse, leading to reduction in airflow ("hypopnea"), cessation of airflow ("apnea"), increase in airflow turbulence or increased resistance to airflow within the airway. In the instance of collapse, the upper airway is blocked, breathing stops, air movement to the lungs ceases, and the oxygen level in the blood tends to decrease. As a response to this process (or to less severe manifestations, such as hypopneas or increased airway resistance), a brief arousal usually occurs in the brain. As a consequence of the brief arousal, the muscle tone in the walls of the upper airway returns to waking levels, and the airway abnormality is corrected - i.e. airway resistance and patency return to normal levels.
Generally, following each event, the patient returns to sleep, until another partial or complete upper airway collapse occurs and the process repeats itself.
Depending on the severity in an individual case, the number of events may range from a few per hour of sleep to more than 100 events per hour of sleep. This process disrupts normal sleep. As a consequence, patients typically suffer from the effects of sleep deprivation. Such effects may include daytime drowsiness, tiredness or fatigue, difficulties with mental concentration or memory, mood changes, reductions in performance or increases in mistakes, and increased risk of accidents. Additionally, OSA is known to increase the risk of development of other medical problems Snoring is a mild form of sleep-disordered breathing in which increased airflow turbulence occurs. The snoring sounds result from tissue vibration within the nasal or oral airway. While snoring has been traditionally regarded as a social or cosmetic problem, recent studies suggest that snoring may be linked to the development of health problems, including high blood pressure.
Airway closure during sleep generally occurs at one or both of two levels in the upper airway: the soft palate and the hypopharynx (base of the tongue).
At either level, the anterior tissue can collapse against the posterior pharyngeal wall, which makes up the rear wall of the throat. Additionally, the side (lateral) walls of the upper airway can collapse inward partially, or completely against each other.
The lateral walls of the airway are susceptible to collapse in many patients with obstructive sleep apnea and other forms of sleep-related breathing disorders.
In these cases, prevention of collapse of the airway only in the anterior-posterior dimension is insufficient to maintain normal airway patency. Even after extensive airway surgery for sleep apnea (which primarily addresses the anterior-posterior dimension of the airway), the patient may continue to have problems with breathing during sleep, due to lateral wall collapse or dysfunction.
Several types of treatment are available for obstructive sleep apnea and other sleep-related breathing disorders. The most common treatment consists of an air pressure delivery system that applies greater than atmospheric pressure to all walls of the upper airway to reduce the potential for full or partial collapse.
Many people have difficulty using this device or prefer not to use it for various reasons. Also, surgical reconstruction of the airway or dental devices may be used. These treatments, however, often fail to treat the problem adequately.
Accordingly, a need exists in the art for an improved method and system for treating sleep apnea and other sleep-related breathing disorders.
SUMMARY OF THE INVENTION
Embodiments of the present invention are generally directed to uses of a system of magnets for treating sleep-related breathing disorders and for opening airway passages. In one embodiment, the system includes a first magnet attached to a first lateral pharyngeal wall, and a second magnet attached to a second lateral pharyngeal wall. The second magnet is positioned opposite the first magnet across an upper airway.
In another embodiment, the system includes a first magnetically susceptible material attached to a first lateral pharyngeal wall and a second magnetically susceptible material attached to a second lateral pharyngeal wall.
The second magnetically susceptible material is positioned opposite the first magnetically susceptible material across an upper airway. The system further includes a first magnet disposed outside the body and lateral to the first magnetically susceptible material, and a second magnet disposed outside the body and lateral to the second magnetically susceptible material.
In yet another embodiment, the system includes a first magnet attached to a first lateral pharyngeal wall and a second magnet attached to a second lateral pharyngeal wall. The second magnet is positioned opposite the first magnet across an upper airway. The system further includes a third magnet disposed inside the upper airway directly across from the first magnet and a fourth magnet disposed inside the upper airway directly across from the second magnet.

DETAILED DESCRIPTION
Figure 1A illustrates a coronal view of an upper airway 100 having a system for treating sleep apnea (and other sleep-related breathing disorders, e.g., snoring) in accordance with one embodiment of the invention. The upper airway 100 is generally defined by the anterior pharyngeal wall 110, two lateral pharyngeal walls 120, 130 and the posterior pharyngeal wall 140. The lateral pharyngeal walls 120, 130 generally include lateral pharyngeal tissue extending superiorly to the velopharynx and inferiorly to the epiglottis. The posterior pharyngeal wall 140 generally includes posterior pharyngeal tissue extending superiorly to the velopharynx and inferiorly to the epiglottis. The anterior pharyngeal wall 110 generally includes a base portion of the tongue 150, the soft palate 210 and the uvula 220 (shown in Figure 2). Magnetically susceptible material 115 is attached to the anterior pharyngeal wall 110, magnetically susceptible material 125 is attached to the lateral pharyngeal wall 120, and magnetically susceptible material 135 is attached to the lateral pharyngeal wall 130. In one embodiment, magnetically susceptible materials 115, 125, 135 are attached to the respective pharyngeal walls by surgical sutures or bonding material, such as surgical glue. Other means for attaching the magnetically susceptible materials to the pharyngeal walls are also contemplated by embodiments of the invention described herein. In another embodiment, the magnetically susceptible materials 115, 125, 135 may be implanted inside, or embedded beneath the surface of, the respective pharyngeal walls, as shown in Figure 1 B. In yet another embodiment, the magnetically susceptible materials 115, 125, 135 may be coated on the surfaces of the respective pharyngeal walls.
The magnetically susceptible materials 115, 125, 135 may be materials, which are not magnets, but are susceptible to magnetic fields, such as ferromagnetic materials. As such, magnetically susceptible materials 115, 125, 135 would not interact with each other in the absence of a magnetic field, such as, during daytime, as opposed to permanent magnets that would potentially interact with each other at all times, which may be inappropriate or even deleterious (e.g., during speaking or swallowing) to a person's health. Magnetically susceptible materials 115, 125, 135 may be in the form of plates, discs, spheres, bars, multiple small pieces, mesh and the like. In an alternate embodiment, the magnetically susceptible materials 115, 125, 135 may be replaced with magnets, such as permanent magnets with magnetic fields of fixed strength or variable magnets (e.g., electromagnets) with magnetic fields of variable strength (including zero if not activated).
Magnet 160 is positioned outside the body and lateral to magnetically susceptible material 125, while magnet 170 is positioned outside the body and lateral to magnetically susceptible material 135, and magnet 180 is positioned outside the body and anterior to magnetically susceptible material 115.
Magnets 160, 170, 180 may be attached or placed adjacent to the outer skin 151 of a patient with means, such as a neckband or a chin strap. In one embodiment, magnets 160, 170, 180 may be implanted beneath the outer skin surface, such as, beneath the front skin 211 of the cheek 266 for magnet 160, as shown in Figure 2.
Magnet 160 is configured to attract magnetically susceptible material 125 toward magnet 160 so that movement of the lateral pharyngeal wall 120 toward closure of the upper airway 100 may be opposed. Magnet 170 is configured to attract magnetically susceptible material 135 toward magnet 170 so that movement of the lateral pharyngeal wall 130 toward closure of the upper airway 100 may be opposed. Magnet 180 is configured to attract magnetically susceptible material 115 toward magnet 180 so that movement of the anterior pharyngeal wall 110 toward closure of the upper airway 100 may be opposed. In this manner, the cross sectional dimensions (e.g., the length or width) of the upper airway 100 may be increased or prevented from decreasing, thereby allowing patency of the upper airway 100 to be maintained.
Force fields between magnet 160 and magnetically susceptible material 125 and between magnet 170 and magnetically susceptible material 135 act to keep the soft tissue of the lateral pharyngeal walls 120, 130 from collapsing.
Force fields between magnet 180 and magnetically susceptible material 115 act to keep the soft tissue of the anterior pharyngeal wall 110 from collapsing toward the posterior pharyngeal wall 140.
Figure 3 illustrates a coronal view of an upper airway 300 having a system 350 for treating sleep apnea (and other sleep-related breathing disorders, e.g., snoring) in accordance with another embodiment of the invention. The system 350 includes magnet 315 attached to an anterior pharyngeal wall 310, magnet 325 attached to lateral pharyngeal wall 320, magnet 335 attached to lateral pharyngeal wall 330, and magnet 345 attached to posterior pharyngeal wall 340. In one embodiment, magnets 315, 325, 335, 345 are attached to the respective pharyngeal walls by surgical sutures or bonding material, such as surgical glue. Other means for attaching the magnets to the pharyngeal walls are also contemplated by embodiments of the invention described herein. In another embodiment, magnets 315, 325, 335, 345 may be implanted inside (e.g., embedded beneath the surface of) the respective pharyngeal walls. In yet another embodiment, magnets 315, 325, 335, 345 may be coated on surfaces of the respective pharyngeal walls.
Magnets 315, 325, 335, 345 may be permanent magnets with magnetic fields of fixed strength or variable magnets, such as electro-magnets, with magnetic fields of variable strength (including zero if not activated).
Magnets 315, 325, 335, 345 are oriented such that the same magnetic poles of the magnets 315, 325, 335, 345 face each other, e.g., north poles facing other north poles. In operation, magnets 315, 325, 335, 345 are configured to repel each other, thereby opposing closure of the upper airway 300 without the use of external magnets.
Figure 4 illustrates a coronal view of an upper airway 400 having a system 450 for treating sleep apnea (and other sleep-related breathing disorders, e.g., snoring) in accordance with yet another embodiment of the invention. The system 450 includes magnet 425 attached to lateral pharyngeal wall 420 and magnet 435 attached to lateral pharyngeal wall 430. In one embodiment, magnets 425, 435 are attached to the respective lateral pharyngeal walls by surgical sutures or bonding material, such as surgical glue. Other means for attaching the magnets to the lateral pharyngeal walls are also contemplated by embodiments of the invention described herein. In another embodiment, magnets 425, 435 may be implanted inside (e.g., embedded beneath the surface of) the respective lateral pharyngeal walls. In yet another embodiment, magnets 425, 435 may be coated on surfaces of the respective lateral pharyngeal walls.
Magnets 425, 435 may be permanent magnets with magnetic fields of fixed strength or variable magnets, such as electro-magnets, with magnetic fields of variable strength (including zero if not activated). Magnets 425, 435 are oriented such that the same magnetic poles of the magnets 425, 435 face each other, e.g., north pole facing other north pole. In operation, magnets 425, 435 are configured to repel each other, thereby opposing closure of the upper airway without the use of external magnets.
