Organized around reducing vertigo and dizziness associated with diseases of the inner ear, part of the Otolith Sound Inc effort is targeted at enabling remediation of motion sickness. The firm has developed a wearable device that allows the User to ignore undesired sensory information. O·to·lith: each of three small oval calcareous bodies in the inner ear of vertebrates, involved in sensing gravity and movement. Otoliths headworn medical device applies localized mechanical stimulation to the vestibular system through calibrated vibrations. It is primarily intended for use by chronic vertigo patients, for whom there are limited treatment options. Launched at the Halcyon Incubator, in June 2021 management announced the firm had received US Food and Drug Administration (FDA) Breakthrough Device designation for its medical device that is designed to be prescribed by physicians for the treatment of vertigo.
