Flexible Ribbon Replaces Brain Functions

A hi-tech spinal implant could give hope to paralysed people after laboratory tests confirmed its effectiveness.

The e-Dura device, a flexible ribbon embedded with electronics and drug delivery mechanisms, was developed by scientists at the Swiss Federal Institute of Technology in Lausanne.

It mimics soft tissue around the spine to prevent rejection by the body, and can remain implanted for up to ten years before it needs to be replaced. Chemicals and electrodes in the device effectively take over the brain's role by stimulating nerves.

In tests, paralysed rats fitted with the ribbon were able to walk again after just a few weeks of training.

"Our e-Dura implant can remain for a long period of time on the spinal cord or cortex," said Professor Stéphanie Lacour of the Institute.

"This opens up new therapeutic possibilities for patients suffering from neurological trauma or disorders, particularly individuals who have become paralyzed following spinal cord injury."

It is believed the e-Dura could also help patients with epilepsy, Parkinson's disease and those needing pain management. The team anticipates clinical trials in humans within the next few years.
