EXTRAVASCULAR LEAD DESIGNS FOR OPTIMIZED PACING AND SENSING HAVING SEGMENTED, PARTIALLY ELECTRICALLY INSULATED DEFIBRILLATION COILS
Abstract:
A lead body having a defibrillation electrode positioned along a distal portion of the lead body is described. The defibrillation electrode includes a plurality of electrode segments spaced a distance apart from each other. At least one of the plurality of defibrillation electrode segments includes at least one coated portion and at least one uncoated portion. The at least one coated portion is coated with an electrically insulating material configured to prevent transmission of a low voltage signal (e.g., a pacing pulse) while allowing transmission of a high voltage signal (e.g., a cardioversion defibrillation shock). The at least one uncoated portion is configured to transmit both low voltage and high voltage signals. The lead may also include one or more discrete electrodes proximal, distal or between the defibrillation electrode segments.
