Devices, systems, and methods to fixate tissue within the regions of body, such as the pharyngeal conduit
View Patent ↗Devices, systems and methods develop static and/or kinetic and/or pressure forces to fixate or brace tissue in targeted pharyngeal structures and individual anatomic components within the pharyngeal conduit.
1. An apparatus comprising a structure sized and configured for implantation in tissue within a tongue along an airway, the structure comprising a shape memory material dynamically changeable, when activated by external stimulus, from a first kinetic phase state having mechanical properties not significantly affecting native tongue tissue conditions to a second kinetic phase state different than the first kinetic phase state and comprising an elastically loaded condition having mechanical properties that fixate native tongue tissue conditions to resist collapse of the tongue in the airway.
2. An apparatus according to claim 1 , wherein the shape memory material comprises a plastic material, and/or a fabric material, and/or a ceramic material, or a combination thereof.
3. An apparatus according to claim 1 , wherein the shape memory material comprises a shape memory ferromagnetic material.
4. An apparatus according to claim 1 , wherein the shape memory material comprises a thermal shape memory material.
5. An apparatus according to claim 1 , wherein the external stimulus includes a magnetic field, or temperature condition, or electromagnetic energy, or a combination thereof.
6. A system comprising at least two apparatuses, at least one of the apparatuses comprising an apparatus as defined in claim 1 .
7. A system according to claim 6 , wherein at least two of the apparatuses comprise an apparatus as defined in claim 1 .
8. An apparatus according to claim 1 , wherein the shape memory material comprises a metal material.
9. An apparatus according to claim 1 , wherein the external stimulus includes electrical energy.
10. A method comprising
providing at least one structure sized and configured for implantation in tissue within a tongue along an airway, the structure comprising a shape memory material dynamically changeable, when activated by external stimulus, from a first kinetic phase state having mechanical properties not significantly affecting native tongue tissue conditions to a second kinetic phase state different than the first kinetic phase state and comprising an elastically loaded condition having mechanical properties that fixate native tongue tissue conditions to resist collapse of the tongue in the airway,
implanting the structure in a tongue when in the first kinetic phase state, and
resisting collapse of the tongue in the airway by applying the external stimulus to change the first kinetic phase state to the second kinetic phase state.
