摘要： A method and system for charge imbalance compensation in a stimulating medical device is provided. The stimulating medical device includes at least one electrode contact configured for providing stimulation to a recipient. A charge imbalance compensation system in the stimulating medical device measures any residual charge remaining on the electrode contact that may result from an imbalance in the applied stimulation. If the measured residual charge exceeds a threshold, the charge imbalance compensation system causes a compensator current to be applied to reduce the residual charge. This residual charge may be measured by measuring a potential difference between the electrode contact and a reference electrode; or, by measuring a potential difference across a capacitor in-series with the electrode contact.

摘要： A medical stimulation device such as a cochlear implant configured to provide stimulation of one or more spatially-restricted contiguous portion(s) of the spiral array of auditory nerve fibers in the cochlear (“discrete stimulation regions”). Each discrete stimulation region is defined by the constructive and/or destructive interference of stimulating and limiting signals simultaneously applied to electrode channels of an implanted electrode array, the stimulating and limiting signals being determined based upon transimpedance measurements of intracochlear electrode channels of the implanted electrode array representing specific spread functions of an individual recipient. The stimulating signal is preferably applied through a targeted electrode channel; that is, one or more successive electrodes which is/are adjacent to the discrete stimulation region. The targeted electrode channel is selected to represent a sound based on the outputs of a sound processor to stimulate neural activity in the discrete stimulation region to thereby cause a percept of the represented sound. The size of the discrete stimulation region is defined by the limiting signal(s) applied to electrode channel(s) other than the targeted electrode channel, and which negate(s) current spread which would otherwise occur in response to the stimulating signal.

摘要： Apparatus and method for at least partially fitting a medical implant system to a recipient is described. The medical implant system is configured to provide electrical stimulation and at least one other mode of stimulation to the recipient.

摘要： Assessment of neuron excitation is implemented by quantifying the interaction between focused and unfocused stimulation applied to a cochlear array. By applying focused and unfocused stimulation to the electrode array and comparing the difference in the responses to the two types of stimulation the interaction may be determined. The magnitude of the interaction may be related to neural excitation and using this data a neural excitation profile may be determined.

摘要： A tinnitus suppression device using an in-the-canal external ear canal pressure regulating device to alter the pressure of the fluid of the external ear canal interior of the pressure regulating device. The device has a body which can be inserted into the external ear canal and which seals the canal from ambient pressure. An adjustably sized body such as a collapsible bulbous portion or a bellows type wall provides a mechanism for altering the pressure in the canal. Either a valve or a mechanical displacement device maintains the pressure differential created.

摘要： An electrode adapted to be utilized within the external ear canal for applying/recording electrical signals to/from the neural/neuromuscular system of a person having an external ear canal and adjacent tympanic membrane. The electrode utilizes an elongated flexible body having a proximate end and a distal end. The elongated flexible body is stiff enough to be inserted into the external ear canal but is flexible enough to bend if the electrode is inserted against the tympanic membrane without rupturing the tympanic membrane. A compressible material is mounted at the distal end of the body and an electrically conductive gel is carried by the compressible material. An electrical conductor communicates with the body and electrically couples the conductive gel to the proximate end of the electrode.
