    Abstract: Systems and method ablate motor nerve tissue by inserting an operative element connectable to an ablation energy generator into a defined percutaneous tissue region. The systems and methods apply stimulant energy in the defined percutaneous tissue region to stimulate targeted motor nerve tissue prior to ablation by the operative element. Application of the nerve ablation energy can permanently eliminate the function of a targeted motor nerve branch, to thereby inactivate a selected muscle. The muscle inactivation may, e.g., treat dystonias and other hyperfunction neuromuscular dysfunctions in the face and neck, such as torticollis, blepharospasm, and uncontrolled grimacing. The muscle inactivation may also provide cosmetic results, to eliminate or prevent aesthetically displeasing skin furrows, frowning wrinkles, or neck bands, which can arise from normal muscle contraction or prolonged exposure of the face to the sun.

    Abstract translation: 系统和方法通过将可连接到消融能量发生器的操作元件插入到限定的经皮组织区域来消融运动神经组织。 系统和方法在定义的经皮组织区域中施加兴奋剂能量，以在手术元件消融之前刺激目标运动神经组织。 神经消融能量的应用可以永久地消除目标运动神经分支的功能，从而使所选择的肌肉失活。 肌肉失活可以例如治疗面部和颈部的肌张力障碍和其他亢进的神经肌肉功能障碍，例如斜颈，眼睑痉挛和不受控制的做法。 肌肉失活还可以提供美容效果，以消除或预防由正常肌肉收缩或面部长时间暴露于太阳而引起的美学上令人不快的皮肤皱纹，皱眉皱纹或颈带。

    Abstract: An apparatus includes a first expandable member that is expandable by an expansion medium. The first expandable member includes an exterior and a plurality of apertures. The expansion medium is released from the first expandable member when a sufficient pressure is applied to the expansion medium housed in an interior of the first expandable member. A second expandable member is positioned at least partially adjacent to the first expandable member. The second expandable member is configured to receive at least a portion of the expansion medium from the interior of the first expandable member. An electromagnetic energy delivery device is coupled to one of the first or second expandable members and is configured to be coupled to a power source. The first and second expandable members are sized to be expanded sufficiently to open a sphincter.
