Two approaches are given in the book using an upper-airway stimulation based on the pathogenesis of an obstructive sleep apnea. Implantable electronics are devised to control the tongue and the soft palate considering that they are the major pharyngeal muscles contributing to the apnea. First, for tongue control, a cuff electrode was designed and fabricated to stimulate the hypoglossal nerve, which innervates to the tongue muscle. Rare-earth magnets were embedded in the cuff for easy and repeatable installation of the electrode. For soft palate control, a palatal implant system was firstly developed to contract the soft palate muscle by applying electrical stimuli. Comprised of an implant, an intra-oral device, and an external controller, the palatal implant system is fully powered and controlled by means of wireless communication. The approaches were demonstrated in both in vitro and in vivo assessments, in collaboration with department of Otorhinolaryngology, Seoul National University Bundang Hospital. .Springer theses.Sleep apnea syndromesBiomedical engineeringSleep apnea syndromes.Biomedical engineering.616.209Seo Jungmin1226661MiAaPQMiAaPQMiAaPQBOOK9910484315203321Development of implantable electronics as novel approaches to obstructive sleep apnea2848234UNINA
