Abstract

"ESTIMULADOR DE OUVIDO INTERNO, IMPLANTáVEL, DE CANAIS MúLTIPLOS". é descrito um dispositivo para a estimulação da ramificação da transmissão auditiva do oitavo nervo. O mesmo utiliza eletrodos projetados para restringir o campo elétrico à região de seu respectivo grupo de fibra de nervo e produzir um campo de gradiente para cada canal de tal forma que as características de latência das fibras nervosas de um dado canal provocará uma queima sequencial (corrente) das fibras nervosas durante uma porção do pulso de estímulo de canal. No sistema análogo, os canais de fibra nervosa são estimulados em sequência mas com seu estímulo sobrepondo-se a seu canal anterior por uma quantidade igual ao período de latência mais curto do dito canal. Durante o período em que um pulso de estímulo provoca a corrente da fibra nervosa, a amplitude de pulso é modulada com as informações de áudio. Além disso, durante a corrente de fibra nervosa, o meio elétrico ou a forma da sonda compensam as características de resistência duração das fibras nervosas individuais. No sistema digital não há corrente, uma vez que há um tempo de queima único para as fibras nervosas em um canal. A sobreposição do canal existe por um número de canais e a modulação de áudio fica na forma de uma modulação de frequência da frequência de sequência de canal."IMPLANTABLE INTERNAL EAR STIMULATOR OF MULTIPLE CHANNELS". a device is described for the stimulation of the auditory transmission branch of the eighth nerve. It uses electrodes designed to restrict the electric field to the region of its respective nerve fiber group and produce a gradient field for each channel in such a way that the latency characteristics of the nerve fibers in a given channel will cause a sequential burning (current ) of nerve fibers during a portion of the channel stimulus pulse. In the analogous system, the nerve fiber channels are stimulated in sequence but with their stimulus overlapping their previous channel by an amount equal to the shorter latency period of said channel. During the period that a stimulus pulse causes nerve fiber current, the pulse amplitude is modulated with the audio information. In addition, during the nerve fiber current, the electrical medium or the probe shape compensates for the resistance characteristics of individual nerve fibers. In the digital system there is no current, as there is a single burning time for nerve fibers in a channel. The channel overlap exists for a number of channels and the audio modulation takes the form of a frequency modulation of the channel sequence frequency.
