Cuff Electrodes

Relative positions of the electrodes in the rings within a cuff.

In the development of neuroprostheses to restore sensory and motor function to disabled patients the choice of the electrodes to be used remains an important consideration. The optimal electrode design should be minimally invasive and be capable of recording or stimulating selectively a large number
of nerve fibers.

Additionally, the electrodes should be capable of delivering stimulation within electrochemically safe limits. The use of a multi-contact cuff electrode for stimulation and recording from peripheral nerves has been shown promising. Nerve cuffs with 16 electrodes, comprising 4 rings of 4 electrodes, were implanted around the sciatic nerve.
