    • A guide catheter includes an outer guide having an open lumen and a longitudinal pre-stress line extending between a distal end and a proximal end of the outer guide. The outer guide has a longitudinal stiffness that facilitates transmission of forces and prevention of kinking during steering of the outer guide within cardiac vasculature and structures. An inner guide has an open lumen and is movably displaceable within the open lumen of the outer guide. At least a distal end of the outer guide and inner guide are dimensioned for passage into the patient's coronary sinus. A guide handle is connected to the proximal end of the outer guide and includes a longitudinal pre-stress line separable into at least two sections such that guide handle separation splits the outer guide along the longitudinal pre-stress line at the proximal end of the outer guide.
    • 引导导管包括具有开口腔和在外引导件的远端和近端之间延伸的纵向预应力线的外引导件。 外引导件具有纵向刚度,其有助于力的传递并且防止在心脏血管和结构内的外导向器的转向期间的扭结。 内部引导件具有开放的内腔,并且可在外部引导件的开口腔内移动地移位。 至少外引导件和内引导件的远端的尺寸被设计成用于通过患者的冠状窦。 引导手柄连接到外引导件的近端,并且包括可分成至少两个部分的纵向预应力线,使得引导手柄分离在外部引导件处沿着纵向预应力线在外部的近端分开 指南。

    • A method of accessing lateral branch veins of the coronary sinus with a pacing lead and guide catheter assembly. The guide catheter has an open lumen extending therethrough and a distal end provided with a pre-formed guide curve, while the pacing lead has a distal end provided with a first curve and a second curve extending proximally from the first curve. The guide catheter is inserted into an access vessel of the heart and advanced along the access vessel to the coronary sinus. The pacing lead is inserted into the guide catheter lumen and advanced distally through the guide catheter lumen. The pacing lead is rotated by advancing the second curve of the pacing lead through the guide curve to align the first curve with a pre-determined plane. The first curve of the pacing lead into one of the lateral branch veins of the coronary sinus.
    • 一种采用起搏引导和引导导管组件来获取冠状窦的横向分支静脉的方法。 引导导管具有延伸穿过其中的开口腔和设置有预先形成的引导曲线的远端,而起搏引线具有设置有第一曲线的远端和从第一曲线向近侧延伸的第二曲线。 引导导管被插入到心脏的进入容器中并且沿着进入容器前进到冠状窦。 起搏引线插入引导导管内腔,并通过引导导管腔远端前进。 通过使起搏引线的第二曲线通过引导曲线使起搏引线旋转,以将第一曲线与预定平面对齐。 起搏的第一条曲线导致冠状窦的一个横向分支静脉。

    • A guide catheter assembly for accessing lateral branch veins of the coronary sinus includes a guide catheter and a pacing lead. The guide catheter has a central lumen therethrough, a proximal end and a distal end pre-formed with a guide curve. The pacing lead is slidably receivable within the guide catheter lumen. The pacing lead has a proximal end and a distal end formed with a first curve and a second curve extending proximally from the first curve. The second curve is adapted to mate with the guide curve to direct the first curve into a selected branch vein of the coronary sinus. The second curve may be pre-formed in the pacing lead, or may be imparted to the pacing lead via a stylet or inner catheter.
    • 用于进入冠状窦的横向分支静脉的引导导管组件包括导向导管和起搏引线。 引导导管具有穿过其的中央腔,近端和预先形成有引导曲线的远端。 起搏引线可滑动地接收在引导导管内腔内。 起搏引线具有近端和远端,其形成有第一曲线和从第一曲线向近侧延伸的第二曲线。 第二曲线适于与引导曲线配合,以将第一曲线引导至冠状窦的选定分支静脉。 第二曲线可以在起搏引线中预先形成,或者可以经由探针或内导管施加到起搏引线。
