Abstract: A steerable catheter includes control handle having a generally tubular housing with a longitudinal slot therein in which an axially or longitudinally movable tow-part slideblock resides, and a generally cylindrical, rotatably mounted thumbwheel surrounding a distal portion of the tubular housing, for controlling the axial translation of the slideblock. The pullwire passes into the distal end of the control handle and is only secured to the proximal part of the two-part slideblock so as to prevent the user from placing the pullwire under compression. A tip radius adjusting wire is attached to and extends distally from a slide actuator in the control handle into and through the main catheter shaft portion. The free distal end of the tip radius adjusting wire is selectably locatable at different positions. The radius of curvature of the tip portion, when deflected, depends upon how far distally into the deflectable tip portion the radius adjusting wire has been advanced by the user. The electrode catheter thus has a deflectable tip whose radius of curvature is adjustable over a relatively wide range.

Abstract translation: 可操纵的导管包括控制手柄，其具有大致管状的壳体，其中具有纵向狭槽，其中轴向或纵向移动的牵引部件滑块位于其中，以及围绕管状壳体的远端部分的大致圆柱形可旋转地安装的指轮，用于控制轴向 幻灯片的翻译。 拉线进入控制手柄的远端，并且仅固定到两部分滑块的近端部分，以防止使用者将拉线放置在压缩状态。 尖端半径调节线附接到控制手柄中的滑块致动器并远离其延伸并且穿过主导管轴部分。 尖端半径调整线的自由端可选地位于不同位置。 尖端部分的弯曲半径在偏转时取决于使用者已经使半径调节线前进到可偏转尖端部分的远端。 因此，电极导管具有可偏转的尖端，其弯曲半径在相对宽的范围内是可调节的。
