Technology Need

The peripheral nerves are a complicated and vast network of nerves that facilitates the communication between brain and spinal cord with different parts of the body. Common causes for peripheral nerve injuries (PNI) include drug injection injury, electrical injury, compression, stretch/ traction injury and laceration. Every year, over half a million of people suffer from transected PNI. Electrical stimulation of peripheral nerve has been prescribed as a form of therapy for these patients. However, most of the peripheral nerve electrode arrays either invasively penetrate the nerve or are difficult to implement for nerves less than 500 µm in diameter. A non-penetrating implantable electrode array for small nerves is needed.

Invention Description/Solution

Researchers in UTA and UTARI have developed an implantable electrode array specifically to accommodate nerves less than 500µm in diameter. The electrode array allows electrical stimulation of peripheral nerves without invasive penetration and accommodates small nerves, as small as 25µm in diameter.  This electrical array is made of flexible transparent materials, which give surgeons a lot of flexibility to perform various nerve regeneration procedures. Electrical interfacing with the nerve using this device will be useful for many applications, including electrical therapies and neurally controlled interfaces.
