Abstract
A programmable neurostimulator and methods, characterized by its modular design is provided, comprising: an internal part based on a mixed-signal ASIC giving access to a complete control on the injected charges, and new channel concept allows performing any stimulation strategy and permit to use any stimulation mode (monopolar, bipolar, quadripolar . . . ); and an external part, built around a DSP and having a digital architecture, which allows to program any signal-processing algorithm, and to store different algorithms and stimulation strategies to be used and selected by the patient himself. An algorithm enables the use of as many filters as needed and the selection of their characteristics and of their associated channels. A vector quantization based stimulation method uses a finite set of element sounds defining all speech characteristics, in such a way that the patient is exposed to a limited number of stimulation sequences allowing the complete identification of the speech phonemes. A wavelet packet based stimulation method is developed towards a new multi-rhythm multi-resolution stimulation strategies that have never been used before. An appropriate hardware as well as a very user-friendly interface clinical s ftware supports all these aspects.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
