Definition : Electric conductors (e.g., wires) designed to conduct electrical biosignals from electrodes placed in or on the body to record and/or monitor equipment either directly or through pre-amplifiers. The leads may be also intended to deliver electric stimuli from an external stimulator to electrodes attached to or implanted into the body. These leads typically consist of flexible wires that are completely isolated except at the electrode tip to prevent electric shock. A variety of lead systems, including single and multiple-lead are available. Lead size, connector type, and other characteristics of the leads must be compatible with the equipment transmitting and or receiving the signal and/or the therapy prescribed. Dedicated leads intended for both external and implantable devices, such as cardiac pacemakers, defibrillators, evoked potential recorders, and electrical stimulators are also available.
