摘要： 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.

摘要： A technique for removing an implanted lead from a body includes the steps of releasably attaching a stylet to both the distal end of the implanted lead and to the proximal end of the implanted lead. This results in a substantially 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 may be used for threaded engagement with a tapped bore at the distal end of the implanted lead and at the proximal end, attachment being provided by a threaded region on the stylet distant from the threaded tip end for threaded engagement with a tapped bore of a connector pin integral with the implanted lead. In this instance, the diameter of the proximal threaded region on the stylet is greater than that of the threaded tip end. In one embodiment, the implanted lead is resiliently extensible and the stylet is greater in length than the implanted lead in its relaxed condition and tension is applied to the proximal end of the implanted lead to thereby stretch it so that the proximal end of the implanted lead is generally coextensive with the proximal end of the stylet.

摘要： 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.

摘要： A method of manufacturing a lead connector end of an implantable medical lead is disclosed herein. The method may include: provide a mold cavity including a feature and a longitudinal axis; place a ring contact in the mold cavity, engage the ring contact with the feature; fill the mold cavity with a mold material, the feature preventing displacement of the ring contact along the longitudinal axis; allow the mold material to cure; remove a resulting lead connector end from the mold cavity; and reduce an excessive diameter of the resulting lead connector end to a finished diameter.

摘要： 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.

摘要： An electrode assembly including a tip electrode and a longitudinally extending axially aligned weld electrode egageably receiving a distal end of a coiled wire strand conductor at a proximal end. A connector member includes a fastener having an enlarged head and a threaded shank, the weld electrode includes an integral weld sleeve with an annular locking tab engageable with the enlarged head to prevent longitudinal movement while permitting rotational movement. The weld electrode has an internal bore for receiving an elongated stylet selectively engageable therewith for implanting and explanting the electrode assembly. 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.
