    • A technique for removing from a body an implanted lead including an active fixation electrode includes the operation of releasably attaching an elongated stylet to the distal end of the implanted lead, specifically, to the electrode at the distal end of the lead. This results in a reasonably unified stylet and implanted lead structure whereby withdrawal of the stylet and of the implanted lead as a unit facilitates the complete removal of the implanted lead from the body. A threaded tip end of the stylet is used for threaded engagement with a tapped bore in the electrode. The threaded tip end of the stylet becomes locked to the electrode by rotating in one direction the threaded portion into the threaded bore and the stylet is removable by counter-rotating the threaded tip end of the stylet relative to the electrode.
    • 一种用于从身体移除包括活性固定电极的植入引线的技术包括将细长管心针可释放地附接到植入引线的远端,特别是引导线远端处的电极的操作。 这导致合理统一的探针和植入引线结构,从而将探针和植入的引线作为一个单元的撤回便于从体内完全去除植入的引线。 通孔的螺纹尖端用于与电极中的螺纹孔螺纹接合。 探针的螺纹尖端通过沿着一个方向将螺纹部分旋转到螺纹孔中而被锁定到电极,并且探针可通过相对于电极相对旋转探针的螺纹尖端来移除。

    • A method of joining a wound element, or coiled wire strand, and a mating component, or integral ledge member, of a body implantable lead assembly wherein the former has a interior passage and an end portion adapted to be received by the latter. In one embodiment, the integral ledge member is formed with an integral collar spaced from a terminal end thereof. The wound element is placed about the receiving portion and over the terminal end of the mating component and against the collar. The components are then joined by thermally fusing them together, preferably by means of a laser. If the collar and the wound element are fabricated of the same alloy, the thickness of the collar and the diameter of the coiled wire strand are designed to be substantially equal. If the components are fabricated of dissimilar alloys, then the thickness of the collar is relatively dimensioned with respect to the diameter of the strand in proportion to the relative thermal diffusivity of the alloy of the collar and of the alloy of the coiled wire strand. In another embodiment, a ring member is placed about, and in engagement with, the receiving portion of the mating component. Then the components are joined, by thermally fusing them together, preferably by targeting a laser beam directly on the ring member, without regard to whether the components are fabricated of the same alloy or of different alloys.
    • 一种将身体可植入引线组件的缠绕元件或线圈绞线以及配合部件或整体凸缘部件接合的方法,其中前者具有内部通道和适于由后者接收的端部。 在一个实施例中,整体壁架构件形成有与其末端间隔开的整体的套环。 缠绕元件围绕接收部分放置在配合部件的终端上并且靠在套环上。 然后通过将它们热熔合在一起,优选地通过激光将部件连接在一起。 如果套圈和缠绕元件由相同的合金制成,则套环的厚度和螺旋线股的直径被设计成基本上相等。 如果组件由不同的合金制成,则套环的厚度相对于股线的直径相对于套环的合金和螺旋线股的合金的相对热扩散率成比例尺寸。 在另一个实施例中,环构件围绕配合部件的接收部分放置并与之配合。 然后,通过将它们热熔合在一起,优选地通过将激光束直接定位在环构件上而不考虑组件是由相同的合金还是由不同的合金制成,将部件连接在一起。

    • An implantable endocardial lead for use with a cardiac stimulation device includes an electrically active housing including a tubular end region extending to a terminal rim at the distal end of the lead and an electrical conductor within the lead extending between proximal and distal ends. An active fixation electrode within and spaced from the electrically active housing includes an electrically active helix coaxial with the endocardial lead coupled to the distal end of the electrical conductor and movable between a retracted position fully within the housing and an extended position advanced beyond the terminal rim of the housing for effecting penetration into the myocardial tissue. A guide system located proximally of the active fixation electrode serves to rotate the electrically active helix about the longitudinal axis as the helix is moved between the retracted and extended positions.

The tip electrode includes an integral attachment sleeve having an outer peripheral surface extending in a direction away from the tip and having a longitudinally extending tapped bore for engagement with the threaded shank of the connector member. The weld sleeve and attachment sleeve are mutually stepped to prevent their relative rotation when in the locked position.
