    • A method and apparatus for treating a body tissue in situ (e.g., an atrial tissue of a heart to treat) atrial fibrillation include a lesion formation tool is positioned against the heart surface. The lesion formation tool includes a guide member having a tissue-opposing surface for placement against a heart surface. An ablation member is coupled to the guide member to move in a longitudinal path relative to the guide member. The ablation member has an ablation element for directing ablation energy in an emitting direction away from the tissue-opposing surface. The guide member may be flexible to adjust a shape of the guide member for the longitudinal path to approximate the desired ablation path while maintaining the tissue-opposing surface against the heart surface. In one embodiment, the ablation member includes at least one radiation-emitting member disposed to travel in the longitudinal pathway. In another embodiment, the guide member has a plurality of longitudinally spaced apart tissue attachment locations with at least two being separately activated at the selection of an operator to be attached and unattached to an opposing tissue surface. Various means are described for the attachment including vacuum and mechanical attachment. The guide member may have a steering mechanism to remotely manipulate the shape of the guide member.
    • 一种用于原位处理身体组织(例如,心脏的心房组织以治疗)心房颤动的方法和装置包括将病变形成工具定位在心脏表面上。 损伤形成工具包括具有用于放置在心脏表面上的组织相对表面的引导构件。 消融构件联接到引导构件以相对于引导构件沿纵向路径移动。 消融构件具有消融元件,用于将发射方向上的消融能量远离组织相对表面。 引导构件可以是柔性的,以调节用于纵向路径的引导构件的形状以接近所需的消融路径,同时将组织相对表面保持抵靠心脏表面。 在一个实施例中,消融构件包括设置成在纵向通路中行进的至少一个辐射发射构件。 在另一个实施例中,引导构件具有多个纵向间隔开的组织附接位置,其中至少两个组织附接位置在选择要附接并未附接到相对组织表面的操作者处被单独激活。 描述了用于附件的各种装置,包括真空和机械附件。 引导构件可以具有用于远程地操纵引导构件的形状的转向机构。
