    • 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 deployment control system provides controlled deployment of an embolic protection device which may include a guide wire, an expandable filter attached to the guide wire near its distal end, and a restraining sheath that maintains the expanded filter in a collapsed position. The deployment control system includes a torque control device which allows the physician to torque the guide wire into the patient's anatomy and a mechanism for preventing the guide wire from buckling as the restraining sheath is being retracted to deploy the expandable filter. A recovery control system for recovering the embolic protection device includes an inner catheter which extends within a lumen of an outer recovery sheath in a coaxial arrangement. A distal portion of the inner catheter extends beyond another recovery sheath during advancement of the recovery system into the vasculature. The recovery sheath can be advanced over the inner catheter to collapse the expandable filter. The proximal ends of the inner catheter and recovery sheath include handle portions having snap mechanisms which hold the components together as the recovery system is being advanced into the patient's vasculature.
    • 部署控制系统提供栓塞保护装置的可控部署,该栓塞保护装置可以包括引导线,在其远端附近附接到导丝的可扩张过滤器,以及将扩张过滤器保持在折叠位置的限制护套。 部署控制系统包括扭矩控制装置,该扭矩控制装置允许医师将导丝扭转到患者的解剖结构中,以及用于防止导线在收缩护套以展开可膨胀过滤器时弯曲的机构。 用于回收栓塞保护装置的恢复控制系统包括在同轴布置中在外部恢复护套的内腔内延伸的内导管。 在将回收系统推进脉管系统期间,内导管的远端部分延伸超过另一恢复护套。 恢复护套可以在内导管上推进以使可膨胀过滤器折叠。 内导管和恢复护套的近端包括手柄部分,其具有卡扣机构,当回收系统进入患者的脉管系统时,该部件将部件保持在一起。

    • Methods of accessing a destination vessel involve use of a catheter having an outer guide and an inner guide. The outer guide includes an outer guide lumen, a distal end, a proximal end, and a predetermined deflection location proximate the distal end. The inner guide includes an inner guide lumen, a pre-formed distal end, and a proximal end. An access method can involve axially displacing the inner guide beyond the distal end of the outer guide, axially rotating the inner guide relative to the outer guide, and changing a bend angle at the predetermined deflection location of the outer guide to direct the pre-formed distal end of the inner guide for finding and cannulating the destination vessel. A payload can be delivered into the destination vessel via the inner guide, or via the outer guide upon removal of the inner guide.
    • 进入目的地船舶的方法涉及使用具有外部引导件和内部引导件的导管。 外引导件包括外引导腔,远端,近端和靠近远端的预定偏转位置。 内部引导件包括内部引导腔,预先形成的远端和近端。 进入方法可以包括将内部引导件轴向移位超过外部引导件的远端,使内部引导件相对于外部引导件轴向地旋转,并且改变外部引导件的预定偏转位置处的弯曲角度,以引导预成型 内引导件的远端用于找到并插管目的地血管。 有效载荷可以通过内部引导件或通过外部引导件移除到目的地船舶中。
