Abstract
A system for detecting and marking the positions of peripheral nerves is disclosed. A disposable or reusable electrode array comprising a plurality of electrodes is combined with a disposable sensor attachment system comprising conductor islands. In use, the electrode array is connected to a peripheral nerve detection instrument. The disposable sensor attachment system is attached to an electrode sensor region. The sensor attachment system is then adhered to an area of skin, detection is carried out, and then the electrode array is peeled back from the skin, leaving a skin marking guide in place. The skin marking guide is then used to mark areas of interest to a therapist.
