X-Wide Contacts Nerve Cuff

The Nerve Cuffs are made out of biocompatible materials. They are mechanically flexible and can be provided in many geometric configurations and a wide range of sizes. Nerve Cuffs can be used for acute or chronic experiments

The key utility for these cuffs is that the large electrodes' contact areas are ideal for studies requiring high current levels and when using KHz electrical stimulation to achieve the block of activity in peripheral nerves. The reduced impedances are ideal for making sure the output of stimulation sources is not attenuated, so that the true block of nerve activity is achieved.

The X-Wide Nerve Cuffs were developed in partnership with the Georgia Institute of Technology.
