Columbia 700P Electrodes can be used with all NMES devices that treat Dysphagia patients; the FDA approved the electrodes for use on the neck and to be used with primary Dysphagia treatment devices. All of the electrodes are single patient-multiple use application. For added comfort and strength, the electrodes are made from a carbon mesh material. The electrodes measure .6875" and are round in shape. Each electrode has a "mini-snap" connection for a quick connection to lead wires provided with NMES devices. Attached to each set of electrodes is a butterfly tape patch. A lead wire for connection to NMES devices are included.
