Abstract: The invention relates to a spatially adaptive, implanted microcontact structure for neuroprostheses suitable for treating functional disorders of the nervous system for the purpose of reversible anchorage on nerve tissue. The spatially adaptive microcontact structure (RAM) is characterized in particular in that an optimum contact or active connection to nerve tissue is ensured. The implanted microcontact structure comprises subareas that are movable relative to one another and that can be brought into at least two permanent desired positions relative to one another and that can be brought into a desired position during implantation for the purpose of mechanical anchorage to the nerve tissue to be contacted and can also be brought out of one desired position into another during explantation to release the anchorage.

Abstract: The invention relates to a system for the protection of neuroprosthesis operation against unauthorized access to the function or operating data. The system is assigned to neuroprostheses for treating functional disorders of the nervous system. This neuroimplant protection system (NIS) comprises at least one neuroprosthesis component which is in contact or operational connection with nerve tissue. Neuroprosthesis operation takes place only during the period of a specific authorization and/or comprises an authorized data transmission between external component and implanted component and/or an authorized communication for monitoring and/or defining the neuroprosthesis functional state. The communication between external and implanted component is in encrypted form.

Abstract: The invention describes an adaptive, sensory-motor encoder for a visual prosthesis or for an acoustic prosthesis and equipped with a central control unit for signal processing functions, monitoring functions, control functions and external intervention functions as well as with a group of adaptive spatio-temporal filters for the conversion of sensor signals into stimulation impulse sequences, whereby a bi-directional interface is provided for coupling the encoder with an implantable microstructure (2) for stimulation of nerve or glial tissue on the one hand, and on the other hand for function monitoring of brain function.
