Abstract:

The present invention provides an implant for stabilizing the tongue, including: a first anchoring portion for securing a first end of the implant with the mandibula; a control portion connected with the anchoring portion, configured for selectively activating the implant; a flexible portion connected at its proximal end with the control portion, the flexible portion having three-dimensional flexibility in a non-energized state and the flexible portion having a lesser three-dimensional flexibility in a energized state, the flexible portion being selectively switchable between the non-energized and energized states by the control portion, wherein the flexible portion can be an electroactive polymer element having: a composite layer having a polymer substrate and a biocompatible conductive material, wherein the composite layer also can be opposing surfaces; and a conductive polymer layer disposed on at least one of the opposing surfaces of the composite layer; and a second anchoring portion connected with the flexible portion, the second anchoring portion being configured for connecting the implant with the base of the tongue. Some embodiments include a housing designed to conform to the shape of the palate. Some embodiments include an attachment element to secure the device to tissue. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.
