Researchers in the US materials science and neurosurgery have jointly developed an implantable, degradable bioelectric medical device. Animal experiments have shown that it can accelerate peripheral nerve regeneration through pulsed discharge and promote the recovery of damaged peripheral nerves. The study, published in the British journal Nature-Medical on October 8, was completed by researchers at Northwestern University and the University of Washington. Researchers say the wireless control device, which is the size of the coin and the thickness of the paper, can be used for several weeks after being implanted in the body and then naturally absorbed by the body. The device can accelerate the regeneration of peripheral nerves in rats by discharge, and promote the recovery of muscle strength and control ability. Accidents or sports injuries, etc. may cause damage to the peripheral nerves, causing numbness, tingling and weakness of the injured person, sometimes requiring surgery. In the past, this type of surgery was supplemented with electrical stimulation to promote rehabilitation. The researchers said that the new device can continue to discharge the injured part after the operation is completed. John Rogers, co-author of the paper and a professor of materials science and engineering at Northwestern University, said that the device can "play a dose-controllable positive therapeutic function and then 'disappear' in the body without traces." Studies have shown that this flexible device wraps the injured nerve, wirelessly supplies it through an extracorporeal transmitter and controls its discharge stimulation at a specified time. The researchers say that the number of days that the device can function by adjusting the material composition and thickness can be used for several weeks.
