<p>A system of implantable defibrillation leads, and methods for their use. Each lead is provided with an elongated defibrillation electrode surface (31), made up of a plurality of electrode coils (26, 28, 30). Each electrode coil is mutually insulated from other electrode coils, and coupled to a separate electrical connector (12). In some embodiments, the electrical coils are interwound, and each extend along the length of the electrode surface. In other embodiments, the electrode coils are arranged sequentially, and each extend over only a portion of the elongated electrode surface. In use, the individual electrode coils or combination of coils may be selected to define an optimal electrode length and/or surface area for use in conjunction with particular multiple electrode defibrillation system. In addition, the ability to select between individual ones of the plurality of the electrode coils also provides the possibility for repair the defibrillation lead system after implant without the necessity of removing and replacing the defibrillation leads.</p> |
