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.

Magnetic structures develop a magnetic force between a tongue and a posterior pharyngeal wall to stabilize an orientation of the tongue. The magnetic structures include magnetic materials that are sized, configured, and arranged on at least one of the first and second magnetic structures, to maintain a substantially mutually repelling orientation between the first and second magnetic structures during a native range of movement of the tongue relative to the pharyngeal wall, i.e., during swallowing and / or drinking / and or speech.

A system for treating obstructive sleep apnea includes a first element implantable in a tongue and a second element implantable between muscle planes of an inframandibular region. The second element has a first end coupled with the first element and a second end coupled with a hyoid bone for preventing the base of the tongue from collapsing against an opposing pharyngeal wall during sleep. The first and second implantable elements have outer surfaces that are substantially impermeable to tissue in-growth to allow for post-surgical adjustment or removal, if necessary. The first implantable element is elongated and includes a first end, a second end, and a center section located between the first and second ends. The center section is implantable in the tongue, and the first and second ends of the first implantable element are advanceable beneath the tongue for being coupled with the anterior end of the second implantable element.
