°AirRay Cuff electrodes make contact with peripheral nerves. These can also be very finely structured, so that the electrodes interfacing them may only have a diameter of 100 µm. The implantation of the cuff represents a big challenge in these small dimensions. In a short video we have compiled a few tips around the implantation […]

How responsive approaches enable personalized therapies Neuromodulation can be an effective treatment for a variety of neurological and neuropsychiatric disorders, such as Parkinson’s disease, epilepsy, traumatic brain injuries, and obsessive-compulsive disorder (Swann et al., 2018). Electrical stimulation impulses are transmitted to the nerve tissue either in an open or closed treatment circuit (open und closed
The use of electrodes in the peripheral nervous system requires mechanical and electrical stability as well as the gentlest possible handling of the nerve. In order to meet these requirements, we have developed a special contact shape for our °AirRay Cuff electrodes.
