Adaptation and Optimization of an Intraneural Electrode to Interface with the Cervical Vagus Nerve

Silvestro Micera, Ivo Strauss

The modulation of the cervical vagus nerve (VN) using neural electrodes has shown great potential to treat cardiovascular, inflammatory, intestinal, or respiratory dysfunctions. Intraneural electrodes have shown great potentials for other neuroprosthetic a ...

Insertion device for inserting deformable prosthesis into an eye

Diego Ghezzi, Charles-Henri Puncho Jérôme Vila

An insertion device (100; 100') for inserting a retinal prosthesis (200) into the eye of a patient comprises: a handle portion (1; 1') arranged to be grasped by a user of the insertion device (100; 100'), a cannula element (12; 12') arranged to be inserted ...

Materials and technologies for soft implantable neuroprostheses

Stéphanie Lacour, Grégoire Courtine

Implantable neuroprostheses are engineered systems designed to restore or substitute function for individuals with neurological deficits or disabilities. These systems involve at least one uni-or bidirectional interface between a living neural tissue and a ...

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

Silvestro Micera, Stéphanie Lacour, Grégoire Courtine, Eduardo Martin Moraud, Quentin Barraud, Léonie Asboth, Tomislav Milekovic, Marco Capogrosso, Pavel Musienko, Nicolas Vachicouras, Ivan Rusev Minev, Nikolaus Wenger, Jérôme Gandar, Arthur Edouard Hirsch, Natalia Pavlova, Simone Ellen Joze Duis

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 ...

Does an intraneural interface short-term implant for robotic hand control modulate sensorimotor cortical integration? An EEG-TMS co-registration study on a human amputee

Silvestro Micera, Leopoldo Rossini

Purpose: Following limb amputation, central and peripheral nervous system relays partially maintain their functions and can be exploited for interfacing prostheses. The aim of this study is to investigate, for the first time by means of an EEG-TMS co-regis ...
