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 software supports all these aspects.

Abstract: L'invention porte sur un chewing-gum enrobé comprenant environ entre 25 et 99,9 % en poids d'un noyau comprenant au moins un polymère élastomère ou résineux dégradable, sans danger pour l'environnement, et environ de 0,1 à 75 % en poids d'un enrobage. L'invention porte également sur les procédés de préparation de ce chewing-gum. L'enrobage est un sucre dur ou un enrobage sans sucre, un film ou un enrobage mou. L'application d'un enrobage empêche la dégradation des polymères dégradables avant la mastication du fait des effets physiques ou chimiques, ce qui prolonge la durée de vie du chewing-gum dégradable, sans danger pour l'environnement. Après mastication, le chewing-gum se dégrade dans l'environnement et peut être retiré plus facilement que le chewing-gum à base de polymères non dégradables.
