Long-term usability and bio-integration of polyimide-based intraneural stimulating electrodes

Silvestro Micera, Grégoire Courtine, Quentin Barraud, Nawal Noëlle Kinany, Marco Capogrosso, Stanisa Raspopovic, Alessandra Piersigilli, Jacopo Rigosa, Jérôme Gandar, Sophie Marie Marthe Wurth, Polina Shkorbatova, Natalia Pavlova

Stimulation of peripheral nerves has transiently restored lost sensation and has the potential to alleviate motor deficits. However, incomplete characterization of the long-term usability and bio-integration of intra-neural implants has restricted their us ...

Fascicular nerve stimulation and recording using a novel double-aisle regenerative electrode

Silvestro Micera

Objective. As artificial prostheses become more refined, they are most often used as a therapeutic option for hand amputation. By contrast to extra- or intraneural interfaces, regenerative nerve electrodes are designed to enable electrical interfaces with ...

Correlation between muscular and nerve signals responsible for hand grasping in non-human primates

Frédéric Pierre Gérald Michoud

Neuroprosthetic devices that interface with the nervous system to restore functional motor activity offer a viable alternative to nerve regeneration, especially in proximal nerve injuries like brachial plexus injuries where muscle atrophy may set in before ...

A Computational Model for Epidural Electrical Stimulation of Spinal Sensorimotor Circuits

Silvestro Micera, Grégoire Courtine, Marco Capogrosso, Stanisa Raspopovic, Pavel Musienko, Nikolaus Wenger, Janine Beauparlant

Epidural electrical stimulation (EES) of lumbosacral segments can restore a range of movements after spinal cord injury. However, the mechanisms and neural structures through which EES facilitates movement execution remain unclear. Here, we designed a comp ...

Use of an Implanted Sacral Nerve Stimulator to Restore Urine Voiding in Chronically Paraplegic Dogs

Stéphanie Lacour

Background Loss of urinary control after spinal cord injury increases risk of urinary tract disease and is problematical for owners of affected dogs. Objectives To design, implant, and test a sacral nerve stimulating device for controlling urine voiding in ...

Magnetization transfer-based 3D visualization of foot peripheral nerves

Cristina Granziera, Giulio Gambarota

PURPOSE: To investigate magnetization transfer (MT) effects as a new source of contrast for imaging and tracking of peripheral foot nerves. MATERIALS AND METHODS: Two sets of 3D spoiled gradient-echo images acquired with and without a saturation pulse were ...

Robotic system for cervical spine surgery

Charles Baur

Background In contemporary surgical clinical practice, spinal instability is often treated with mechanical stabilization techniques in order to protect the spinal cord and nerve roots. These techniques involve placing screws in defined regions of the verte ...

Comparison of 4D Phase-Contrast MRI Flow Measurements to Computational Fluid Dynamics Simulations of Cerebrospinal Fluid Motion in the Cervical Spine

Nikolaos Stergiopoulos, Bryn Andrew Martin

Cerebrospinal fluid (CSF) dynamics in the cervical spinal subarachnoid space (SSS) have been thought to be important to help diagnose and assess craniospinal disorders such as Chiari I malformation (CM). In this study we obtained time-resolved three direct ...

Stump nerve signals during transcranial magnetic motor cortex stimulation recorded in an amputee via longitudinal intrafascicular electrodes

Silvestro Micera, Jacopo Rigosa

Do central and peripheral motor pathways associated with an amputated limb retain at least some functions over periods of years? This problem could be addressed by evaluating the response patterns of nerve signals from peripheral motor fibers during transc ...

Magnetization Transfer (MT) Segmentation of foot peripheral nerves at 3 T

Cristina Granziera, Giulio Gambarota

The ability of tracking peripheral nerves in foot could be of great benefit for a number of investigations, which include traumas, diabetes and infections. Previous approaches to nerve tracking have employed diffusion tensor imaging (DTI, [1, 2]), which is ...
