An example catheter includes a handle assembly having a control member, an elongate body, a pull wire, and at least one radiopaque marker. The elongate body defines a lumen configured to receive an medical electrical lead including at least one electrode array. The elongate body includes a proximal portion coupled to the handle assembly and a distal portion that includes an articulating segment and a preformed curve segment. The at least one radiopaque marker is positioned on the distal portion. The pull wire extends from the control member and is anchored to the elongate body distal to the articulating segment such that actuation of the control member controllably bends the articulating segment in a first curve in a first geometric plane. The preformed curve segment defines a second curve in a second geometric plane different from the first geometric plane. 一种示例导管包含具有控制构件的手柄组合件、细长主体、拉线以及至少一种不透射线的标志物。所述细长主体限定管腔，所述管腔被配置成收纳包含至少一个电极阵列的医疗电引线。所述细长主体包含近侧部分和远侧部分，所述近侧部分联接到所述手柄组合件，所述远侧部分包含铰接段以及预先形成的曲线段。所述至少一种不透射线的标志物被
