Spinal Implants to Treat Pain
Scientists at University of Cambridge have developed an ultra-thin inflatable device the size of a human hair that can be used to treat the most severe forms of pain without the need for invasive surgery. It uses a combination of soft robotic fabrication techniques, ultra-thin electronics and microfluidics. It can be rolled up into a tiny cylinder, inserted into a needle, and implanted into the epidural space of the spinal column, the same area where the injections are administered to control pain during childbirth. Once correctly positioned, the device is inflated with water or air so that it unrolls like a tiny air mattress, covering a large section of the spinal cord. When connected to a pulse generator, the ultra-thin electrodes start sending small electrical currents to the spinal cord, which disrupt pain signals.
