    • The invention provides an array of electrodes suitable for use as an auditory prosthesis. The array comprises a carrier member formed from electrically insulating flexible material, having a surface and a core, the carrier member including at least a pair of electrodes molded therein, the electrodes comprising a length of contact material formed in a semi-circular shape, having a convex contact surface and a locking portion defining an internal space. The electrode is molded in the carriers so that the convex contact surface of the electrode is preferably flush with the carrier member surface. The locking portion of the electrode is molded into the core of the carrier member in the electrode connected to a lead wire which is molded in the core of the carrier member. The invention further provides a method for fabricating such an array of bipolar electrodes.

    • A method for determining absolute current density through an implanted electrode measures the fundamental and harmonic components of an electrical current passing through the electrode and estimates the absolute current density from the ratio between the magnitude of the electrical current measured at one of the harmonics on the fundamental frequency. Another method of the invention applies a wideband noise input voltage to the electrode under investigation and measures the spectrum of the input voltage and output current to determine a first transfer function. A second transfer function representing an increase magnitude of wideband noise input voltage is also obtained. A difference transfer function is computed and used to determine absolute current density through the electrode. The methods may be practiced non-invasively.

    • A prosthetic hearing implant capable of independently and concurrently processing multiple audio input signals such that each audio input signal is separately utilized to stimulate the basilar membrane of the implant recipient. A prosthetic hearing implant of the present invention simultaneously receives discrete audio signals from each of one or more audio sources, generates a separate set of one or more stimulations signals for each audio signal, and concurrently applies the stimulation signals to the cochlear. Different channels of stimulation may be allocated to each audio input signal. Alternatively, different modes of stimulation may be used for each input signal. Or, in yet another example, the audio input signals may be time-multiplexed such that the input signals are applied in alternating timeslots. Or, in yet other examples, the input signals may be applied using a combination of stimulation channels, modes of stimulation, and alternating time slots. The stimulation signals may be delivered to the same or different electrodes depending on the quantity and frequency component of the received audio input signals, the quantity of available stimulation channels, and other factors.

    • An apparatus and method for determining stimulation channels for a stimulating device is provided. This method and apparatus may involve computing a set of weights for the plurality of stimulation channels of the stimulating hearing prosthesis. These weights may be determined by determining a transimpedance matrix for the stimulating hearing prosthesis where a diagonal of the transimpedance matrix is determined by extrapolation. A transadmittance matrix may then be computed for this transimpedance matrix. An error may then be computed base on positive off-diagonal terms of the transadmittance matrix. The apparatus and method may determine the weights for the stimulation channels by determining an adjustment to the diagonal of the transimpedance matrix that results in a computed error that does not exceed a specified criterion level.

    • 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.
