摘要:
A carrier is sized and configured for placement in or on a tissue region. The carrier includes at least one interior compartment. At least one ferromagnetic material is carried within the compartment. The compartment and the ferromagnetic material are mutually sized and configured to allow movement of the ferromagnetic material within the compartment in response to magnetic interaction with a magnetic material located outside the carrier. The magnetic interaction can include either a magnetic attracting force or a magnetic repelling force. The carrier can be used in association with a source of magnetism sized and configured for placement in or on a tissue region outside the carrier for magnetic interaction with the ferromagnetic material carried within the compartment, e.g., to stabilize the orientation of a tissue region within an airway.

Systems and methods are provided for resisting posterior movement of the tongue during sleep, thereby keeping an airway open. The systems and methods employ a first structure that can be placed either in or on a tongue within an oral cavity and/or in a region of hyoid muscle. The first structure includes a ferromagnetic material. The systems and methods employ a second structure that can be placed either in or on external tissue outside the oral cavity and/or in or on external tissue outside the oral cavity in a desired relationship with the first structure. The second structure includes a magnetic material that magnetically interacts with the ferromagnetic material by attracting the ferromagnetic material, thereby resisting posterior movement of the tongue.
摘要:
Systems and methods resist posterior movement of both the tongue and the soft palate/uvula during sleep, thereby keeping an airway open. The systems and methods employ first, second, and third structures. The first structure is sized and configured for placement in or on a tongue. The second structure is sized and configured for placement in or on a region of a soft palate or uvula. The third structure is sized and configured for placement in or on tissue in a desired relationship. anterior of the first and second structures. The first and second structures each includes a ferromagnetic material. The third structure includes a magnetic material that magnetically interacts with both the first and second ferromagnetic materials by attracting both the first and second ferromagnetic materials, thereby resisting posterior movement of both the tongue and the soft palate/uvula.
摘要:
A magnetic force system uses a magnetic implant sized and configured to be inserted in the pharynx and another magnetic implant sized and configured to be inserted in the tongue, palate, or pharynx. The system establishes different regions of magnetic interaction between the two implants across the airway, attracting and repelling, such that attractive interaction in one region of the implants combines with repelling interaction in another region of the implants, to provide a “hinge” structure. Alternatively, a magnetic force system that uses three magnetic implants sized and configured to be inserted in the tongue, pharynx, and palate, respectively. The tongue implant is attracted to the palatal implant, and repels the pharyngeal implant, forming a modified “hinge” structure. Forces of magnetic attracting bring tissue together to form a magnetic hinge joint, providing an anchor to stabilize the regions where repelling forces work to separate tissue to keep the airway open.

Systems and methods prevent magnetic implant migration and extrusion in the upper airway. The systems and methods relate both to surgical techniques as well as structural features to address the problem of magnetic implant migration.
摘要:
Devices, systems, and methods employ at least one ferromagnetic structure sized and configured for placement in a tissue region. A component is attached to the structure to stabilize its placement in the tissue region. An anchoring structure holds the component in a state of tension. The anchoring structure can, e.g., take the from of an anchoring body that expands in situ. The anchoring structure can be adjustable for adjusting the state of tension. The component can be elastic, to deflect under load in a prescribed manner and to recover an initial shape when unloaded.
