Abstract: Disclosed examples include technology for the detection and treatment of neotissue formation proximate an implantable stimulator. Neotissue formation can include ossification, scar tissue, soft tissue fibrosis, and other tissue growth. The neotissue formation can be detected by analyzing (e.g., using a machine-learning framework) stimulation data relating to the implantable stimulator. Neotissue formation characteristics can be analyzed to determine appropriate treatment actions for ameliorating the effects of neotissue formation.

Abstract: System and methods for fitting an auditory prosthesis include testing a subset of sound channels for the audio prosthesis. Adjustment values are determined for the tested sound channels, which can be electrodes in a cochlear implant. The adjustment values are efficiently determined by using a mapping function. The determined adjustment values on selected channels are then input into an interpolation function or algorithm to determine adjustment values for non-tested sound channels. The use of interpolation provides for a more efficient fitting process.

Abstract: An alterphasic inverting stimulation strategy for use with a multichannel cochlear implant system consumes less power than similar strategies, yet provides better sound quality. The alterphasic inverting strategy is a strategy wherein stimulation pulses are strictly sequential, and wherein the timing and polarity of the channels is chosen such that positive and negative pulses are alternating in time in accordance with a defined pattern that staggers application of the pulses spatially across all the channels and inverts the polarity of pulses that are near each other either spatially or in time.
