Devices, systems and methods employ magnetic force to resist tissue collapse in targeted pharyngeal structures and individual anatomic components within the pharyngeal conduit during sleep.

Systems and methods selectively stabilize tissue in the oral cavity. The systems and methods implant a first implant element in a bone region within an oral cavity and implant a second implant element in a tongue region within the oral cavity. The systems and methods resist posterior movement of the tongue within the oral cavity by coupling the first implant element to the second implant element within the oral cavity. By coupling, the systems and methods apply force, e.g., tension, between the first and second implant elements.
摘要:
At least one implant structure is sized and configured for implantation in, on, or near an extrinsic muscle region affecting movement and/or shape of a tongue, e.g., a genioglossus muscle. The position of the implant structure is stabilized relative to the extrinsic muscle region to maintain the tongue in a desired orientation, e.g., to maintain patency of an airway.
摘要:
An implant system places magnetic structures in or on tissue that develop a magnetic repelling force between a soft palate a posterior pharyngeal wall. The magnetic repelling force has a magnitude F-mag, where F-mag=f (F-sep, F-nat), and where F-sep is a force required to separate soft palate tissue from pharyngeal wall tissue during sleep, and F-nat is a force exerted by native muscle on the soft palate during swallowing and/or drinking and/or speech. In another embodiment, a palate implant uses attractive magnetic force to keep the airway open.
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:
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.
摘要:
Devices, systems, and methods resist posterior movement of the tongue during sleep, thereby keeping an airway open. An implant device has a ferromagnetic structure that, when implanted, occupies only one lateral side of the tongue when implanted. The ferromagnetic structure magnetically interacts with a magnetized material placed in a desired relationship with the tongue to stabilize a preferred tongue orientation.
摘要:
Systems and methods place a first structure and a second structure in or on different tissue regions for magnetic interaction. The first structure comprises at least one ferromagnetic component, and the second structure comprises an array of magnetic components. The first and second structures are separated during use by a distance, which is defined as a separation between the centers of mass of the ferromagnetic and magnetic components. The distance varies within a working range as a result of native movement of the tissue regions on which the first and second structures are placed. The systems and methods titrate the size and orientation of the magnetic and ferromagnetic components to maintain a relatively constant magnetic field between the two structures within the working range, thereby accommodating relative movement of the tissue regions in the normal performance of bodily functions.
