Abstract:
An otic microprobe system comprising:an integrated unit having an insertion end and a connection end, the integrated unit comprising a fiber optic laser Doppler flowmetry probe constructed and adapted to measure blood flow and velocity; and an electrocochleography electrode; the connection end of the integrated unit being adapted to be coupled to an interface unit, the interface unit having a laser Doppler interface unit including a first laser excitation source and a laser light detector adapted to be coupled to the fiber optic laser Doppler flowmetry probe; a differential bioamplifier adapted to be coupled to the electrocochleography electrode; and a controller adapted to receive inputs from the laser Doppler interface unit and the differential bioamplifier and to generate coordinated electrocochleography and laser Doppler measurements.
