Minimally invasive endovascular electrodes

– a possible alternative to surgically implanted surface electrodes?

Wouldn’t it be great if we could reliably measure our brain’s activities without the need to open the skull? An Australian team is exploring this possibility by adapting a technology from cardiology: A stent, inserted through a catheter into a cerebral blood vessel in the brain. The team modified the stent so that it could function as an electrical recording electrode with various, independent channels.

One single nerve – many different movements!

Functional electrical stimulation of motor nerves or muscles has been used for decades to restore movements in paralyzed patients who suffered a spinal cord injury, for example. The idea is based on the seminal findings by Luigi Galvani in the 18th century. He could induce movements in frog legs when exposing them to electric voltages – at the time, provided by naturally occurring lightning or simple “batteries” made up of different metals.

Neuronal decoding of decreased blood sugar levels: A first step towards closed-loop bioelectronic diabetes treatment

A central vision of bioelectronic medicine is to find ways to regulate body states through electric interactions with the nervous system rather than through administration of pharmaceuticals. Diabetes is one of the first major targets for this novel approach: Even the most advanced existing pharmaceutical therapies are still error-prone and complicated, often leaving patients with unsatisfactory therapeutic results and with frequent harmful episodes.

Wireless Neuromodulation with CorTec Cuff Electrodes and novel ‘Electroparticles’

One of the major sources for complications in chronic neuromodulation are the wires connecting the different parts of the systems, or even penetrating the skin. They account for frequent device failures due to wire breaks and, especially when penetrating the skin, are a permanent risk of tissue irritations or infections.

Electrostimulation with CorTec Cuff Electrodes Inhibits New-onset Autoimmune Diabetes

Type 1 diabetes is an autoimmune disease for which no causal cure exists to date. The only treatment method available consists of closely monitoring blood sugar levels and injecting insulin several times a day. This treatment, however, does not eliminate the cause of the disease, has to be kept up for the patient’s whole life, and comes with frequent complications, as blood sugar levels can reach critical levels when insulin injections are not optimally adjusted.

How to Implant °AirRay Tunnel Cuff Electrodes

°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 ”m. 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 of Cuff electrodes – in this case especially for the °AirRay Tunnel Cuff. In order to demonstrate how cuff and nerve interact served ourselves in the kitchen and got the perfect nerve substitute – spaghettini al dente.

Retrospective Webinar: Using Cuff Electrodes to Study the Peripheral Nervous System

The research in the peripheral nervous system towards new therapies based the approach of bioelectronic medicine has experienced a strong upswing in recent years. In a webinar featuring some users of our cuff electrodes we have presented challenges of this work together with recent successes.

Recording quality of CorTec cuff electrode excels in comparison with other commercial and self-made alternatives

Creating viable electric interfaces for delicate nerve structures is a real challenge –  especially if they are to enable communication with particularly small nerves which are only as thick as a human hair.
