Cambridge researchers have introduced a groundbreaking device capable of wrapping around the spinal cord to enable detailed monitoring and stimulation, potentially eliminating the need for risky brain surgeries in spinal injury treatments. Credit: SciTechDaily.com
Most current approaches to treating spinal injuries involve both piercing the spinal cord with electrodes and placing implants in the brain, which are both high-risk surgeries. The Cambridge-developed devices could lead to treatments for spinal injuries without the need for brain surgery, which would be far safer for patients.
By taking their inspiration from microelectronics, the researchers developed a way to gain information from the whole spine, by wrapping very thin, high-resolution implants around the spinal cord’s circumference. This is the first time that safe 360-degree recording of the spinal cord has been possible – earlier approaches for 360-degree monitoring use electrodes that pierce the spine, which can cause spinal injury.
“It was a difficult process, because we haven’t made spinal implants in this way before, and it wasn’t clear that we could safely and successfully place them around the spine,” said Malliaras. “But because of recent advances in both engineering and neurosurgery, the planets have aligned and we’ve made major progress in this important area.”The devices were implanted using an adaptation to routine surgical procedure so they could be slid under the spinal cord without damaging it.
