A covering can be sized to fit at least partially over or upon a tongue of a patient, where the covering has an engagement mechanism positioned thereon. A retaining device, sized to fit within a mouth of the patient, may be positioned upon the teeth and have a corresponding engagement mechanism positioned thereon for temporarily coupling with the engagement mechanism on the covering. Such a system can be used to maintain or hold a natural position of the tongue within the mouth of the patient to maintain patency of the airway passages. ## Claims ### Claim 1 A method of treating sleep apnea, comprising: positioning a covering at least partially over or upon a tongue of the patient, wherein the covering has a first engagement mechanism positioned on or near an end of the covering such that the first engagement mechanism is positioned to lie upon or near an anterior portion of the tongue; positioning a retaining device within the mouth of the patient, wherein the retaining device has a second engagement mechanism thereon for coupling with the first engagement mechanism; and engaging the first engagement mechanism with the second engagement mechanism whereby axial tension imparted upon the covering by the tongue urges the covering to conform more closely against the tongue to maintain a secure attachment thereto such that an airway is unobstructed by a base of the tongue. ### Claim 2 (depends on 1) The method of claim 1 wherein positioning a covering comprises positioning the covering over at least the anterior portion of the tongue. ### Claim 3 (depends on 1) The method of claim 1 wherein positioning a covering comprises positioning a mesh covering over or upon the tongue. ### Claim 4 (depends on 1) The method of claim 1 wherein positioning a retaining device comprises positioning a mouthguard within the mouth. ### Claim 5 (depends on 1) The method of claim 1 wherein positioning a retaining device comprises positioning the retaining device such that the retaining device is contained completely within the mouth of the patient. ### Claim 6 (depends on 1) The method of claim 1 wherein engaging comprises magnetically coupling the first and second engagement mechanisms to one another. ### Claim 7 (depends on 1) The method of claim 1 wherein engaging comprises mechanically coupling the first and second engagement mechanisms to one another. ### Claim 8 (depends on 1) The method of claim 1 wherein engaging comprises retaining a natural position of the tongue within the mouth. ### Claim 9 A tongue retaining system, comprising: a covering sized to fit at least partially over or upon a tongue of a patient whereby axial tension imparted upon the covering by movement of the tongue urges the covering to conform more closely against the tongue to maintain a secure attachment thereto, the covering having a first engagement mechanism positioned on or near an end of the covering such that the first engagement mechanism is positioned to lie upon or near an anterior portion of the tongue; and a retaining device sized to fit within a mouth of the patient, the retaining device having a second engagement mechanism thereon for coupling with the first engagement mechanism such that a position of the tongue is maintained within the mouth of the patient. ### Claim 10 (depends on 9) The system of claim 9 wherein the covering is sized to fit over at least the anterior portion of the tongue. ### Claim 11 (depends on 9) The system of claim 9 wherein the covering is comprised of a mesh covering. ### Claim 12 (depends on 11) The system of claim 11 wherein the mesh covering is adapted to securely retain the tongue when the covering is tensioned in an axial direction. ### Claim 13 (depends on 9) The system of claim 9 wherein the covering is comprised of a distensible material. ### Claim 14 (depends on 9) The system of claim 9 wherein the first and second engagement mechanisms are magnetically coupled to one another. ### Claim 15 (depends on 9) The system of claim 9 wherein the first and/or second engagement mechanism comprises one or more magnets. ### Claim 16 (depends on 9) The system of claim 9 wherein the first and/or second engagement mechanism comprises a temporary mechanical engagement. ### Claim 17 (depends on 9) The system of claim 9 wherein the retaining device comprises a mouthguard sized to fit within the mouth of the patient. ### Claim 18 (depends on 17) The system of claim 17 wherein the mouthguard is adapted to fit upon a lower row of teeth within the mouth of the patient. ### Claim 19 (depends on 17) The system of claim 17 wherein the mouthguard is adapted to fit upon an upper row of teeth within the mouth of the patient. ### Claim 20 (depends on 17) The system of claim 17 wherein the mouthguard is adapted to fit upon both a lower row and an upper row of teeth within the mouth of the patient. ### Claim 21 A method of retaining a position of a tongue within a mouth of a patient, comprising: positioning a covering at least partially over or upon a tongue of the patient, wherein the covering has a first engagement mechanism positioned on or near an end of the covering such that the first engagement mechanism is positioned to lie upon or near an anterior portion of the tongue; positioning a retaining device within the mouth of the patient, wherein the retaining device has a second engagement mechanism thereon for coupling with the first engagement mechanism; and engaging the first engagement mechanism with the second engagement mechanism whereby axial tension imparted upon the covering by the tongue urges the covering to conform more closely against the tongue to maintain a secure attachment thereto such that the position of the tongue is retained within the mouth. ### Claim 22 (depends on 21) The method of claim 21 wherein positioning a covering comprises positioning the covering over at least the anterior portion of the tongue. ### Claim 23 (depends on 21) The method of claim 21 wherein positioning a covering comprises positioning a mesh covering over or upon the tongue. ### Claim 24 (depends on 21) The method of claim 21 wherein positioning a retaining device comprises positioning a mouthguard within the mouth. ### Claim 25 (depends on 21) The method of claim 21 wherein positioning a retaining device comprises positioning the retaining device such that the retaining device is contained completely within the mouth of the patient. ### Claim 26 (depends on 21) The method of claim 21 wherein engaging comprises magnetically coupling the first and second engagement mechanisms to one another. ### Claim 27 (depends on 21) The method of claim 21 wherein engaging comprises mechanically coupling the first and second engagement mechanisms to one another. ### Claim 28 (depends on 21) The method of claim 21 wherein engaging comprises retaining a natural position of the tongue within the mouth. ### Claim 29 (depends on 24) The method of claim 24 wherein positioning a mouthguard comprises positioning the mouthguard upon a lower row of teeth within the mouth. ### Claim 30 (depends on 24) The method of claim 24 wherein positioning a mouthguard comprises positioning the mouthguard upon an upper row of teeth within the mouth. ### Claim 31 (depends on 24) The method of claim 24 wherein positioning a mouthguard comprises positioning the mouthguard upon a lower row and upper row of teeth within the mouth.
