EXPANDABLE ELECTRODE DEVICE AND METHODS FOR NERVE MODULATION |
摘要 |
<p>Embodiments of the disclosure provide an ablative system for nerve modulation through wall of a blood vessel. The ablative catheter system includes an elongate member having a proximal end and a distal end, a number of electrode elements, an expansion mechanism. The electrode elements are finger-like structures mounted at their proximal ends for pivotal rotation radially outward from the longitudinal axis of the elongate member from a collapsed state. Each electrode element having inner and an outer surface with an electrode portion connected to a source of electrical energy and an insulated portion and a slope surface forming the proximal portion of the inner surface, sloping outward from the longitudinal axis of the elongate member, and a tip portion at the distal portion of the inner surface, angled toward the longitudinal axis of the elongate member. The electrode element inner surfaces in the collapsed state define a central cavity.</p> |
