Auditory Brainstem Implants: Recent Progress and Future Perspectives

Stéphanie Lacour, Nicolas Vachicouras

The auditory brainstem implant (ABI) was first developed nearly 40 years ago and provides auditory rehabilitation to patients who are deaf and ineligible for cochlear implant surgery due to abnormalities of the cochlea and cochlear nerve. The aims of the f ...

Microstructured thin-film electrode technology enables proof of concept of scalable, soft auditory brainstem implants

Stéphanie Lacour, Nicolas Vachicouras, Florian Dylan Fallegger, Christina Myra Tringides, Jennifer Mary Adrienne Alice Macron, Valentina Marie Paggi, Yohann Daniel André Thenaisie

Auditory brainstem implants (ABIs) provide sound awareness to deaf individuals who are not candidates for the cochlear implant. The ABI electrode array rests on the surface of the cochlear nucleus (CN) in the brainstem and delivers multichannel electrical ...

Soft microfabricated neural implants: a path towards translational implementation

Nicolas Vachicouras

Neuroprosthetics are a class of medical devices that aim to restore lost or impaired functions of the nervous system by electrical stimulation or recording of neural tissue. State of the art neural implants suffer today from a mechanical mismatch compared ...

Engineering reversible elasticity in ductile or brittle thin films and products resulting from said engineering

Stéphanie Lacour, Nicolas Vachicouras, Christina Myra Tringides

The present invention relates to how to engineer reversible elasticity in thin films and/or layers and/or substrates, using a repeated Y-shaped motif, which is cut out throughout the film and/or layer and/or substrate. As an example, using a 75 μm thick po ...

Long-term functionality of a soft electrode array for epidural spinal cord stimulation in a minipig model

Stéphanie Lacour, Grégoire Courtine, Giuseppe Schiavone, Jocelyne Bloch, Marco Capogrosso, Nicolas Vachicouras, Fabien Bertrand Paul Wagner, Florian Dylan Fallegger, Xiaoyang Kang, Beatrice Barra

Long-term biointegration of man-made neural interfaces is influenced by the mechanical properties of the implant materials. Substantial experimental work currently aims at replacing conventional hard implant materials with soft alternatives that can favour ...

Engineering reversible elasticity in ductile and brittle thin films supported by a plastic foil

Stéphanie Lacour, Nicolas Vachicouras, Christina Myra Tringides

Reversible deformation is a unique property of elastic materials. Here, we design and fabricate highly stretchable multilayered films by patterning Y-shaped motifs through films of non- elastic materials, e.g. plastics, metals, ceramics. By adjusting the g ...

Biomaterials. Electronic dura mater for long-term multimodal neural interfaces

Silvestro Micera, Stéphanie Lacour, Grégoire Courtine, Quentin Barraud, Léonie Asboth, Eduardo Martin Moraud, Tomislav Milekovic, Marco Capogrosso, Pavel Musienko, Nicolas Vachicouras

The mechanical mismatch between soft neural tissues and stiff neural implants hinders the long-term performance of implantable neuroprostheses. Here, we designed and fabricated soft neural implants with the shape and elasticity of dura mater, the protectiv ...
