Vestibular implant system with internal and external motion sensors

摘要

Abstract: A partially implantable vestibular prosthesis system is described which includes an external movement sensor that is attachable to the outer skin surface of a patient's head for generating an external movement signal which represents movement of the patient's head. An external transmitter is in communication with the external movement sensor and provides an electromagnetic transmission of an implant communication signal which includes a signal component based on the external movement signal and an electrical power component that provides electrical power for implanted system components. An internal movement sensor is implantable under the skin and communication with the internal movement sensor and the external transmitter for generating an implant stimulation signal based on one of the movement signals to electrically stimulate larger neural tissue for vestibular sensation by the patient. 6049313_1 (GHMatters) P92279.AU.2 MILESF 15/12/2014 201 204 107 106 b 109 205 111 (re, 108 c4 104 212 21-q 211
