摘要： An implantable medical electrical lead includes a plurality of conductors that extend continuously, without any intermediary junctions, between a plurality of electrodes and a corresponding plurality of contact members of an in-line connector terminal. A junction between each conductor and the corresponding contact member is preferably formed by first fitting a conductive sleeve, which is coupled to a proximal portion of the conductor, into an eyelet feature of the contact member, which is mounted on a strut member, and then welding the sleeve to the contact member at a pre-formed slot of the contact member, which extends along an external recessed surface thereof. The assembly of the connector terminal preferably completes the construction of the lead, wherein the proximal portion of each conductor is positioned in a helical path, which extends between an elongate body of the lead and the connector terminal, and along which a grip zone is formed.

摘要： An implantable medical lead configured for active fixation in the vasculature of a patient includes an elongated lead body having a central lumen and a distal tip. Disposed within the central lumen are a fixation helix and an elongated member, such as a lead coil, coupled to the fixation helix. The elongated member is adapted to rotate the fixation helix, thereby causing it to advance or retract within the central lumen of the lead body. The lead body includes a window along a portion of its length through which the fixation helix may be affixed to a blood vessel of the patient's vasculature.

摘要： An improved medical lead assembly and method of use is provided. The lead assembly includes a lead body, and a spring member positioned adjacent to the lead body. The spring member may be deployed a selectable amount to maintain the lead body in a fixed location within a patient's body. The spring member may be an expandable coil, a mesh structure that is similar to a stent, or any other similar device that may be positioned in a low-profile state during a lead implant procedure. After the lead is positioned at a target destination, the spring member may be deployed an amount that is selected based on the characteristics of the surrounding tissue, including vessel size. According to one aspect of the invention, the lead assembly may provide means for facilitating chronic lead extraction.

摘要： A distal section of an implantable medical electrical lead body includes a pair of pre-formed arcuate segments between which an approximately straight segment extends. The approximately straight segment includes a first portion extending distally from a first of the pair pre-formed arcuate segments, a second portion extending from the first portion, a third portion extending from the second to a second of the pair pre-formed arcuate segments. An electrode is coupled to the second portion of the approximately straight segment, and the adjacent first portion has a stiffness which is less than that of the first of the pair pre-formed arcuate segments and preferably less than the stiffness of the third portion, so that, when the distal section of the lead body is implanted, for example, within a cardiac vein, the lead buckles to bring the electrode into closer contact with surrounding tissue.
摘要翻译：植入式医疗电引线主体的远端部分包括一对预先形成的弧形段，大致直的段延伸在该弧形段之间。大致直的部分包括从第一对预成形弧形段向远侧延伸的第一部分，从第一部分延伸的第二部分，从该对预成形弧形段中的第二部分延伸到第二部分的第三部分。电极耦合到大致直线段的第二部分，并且相邻的第一部分的刚度小于预先形成的一对弓形段中的第一部分的刚度，并且优选地小于第三部分的刚度，因此当引线体的远侧部分植入心脏静脉内时，引线带扣使电极与周围的组织更接近。

摘要： A cardiac pacing lead having a plurality of individually insulated conductors arranged as a multifilar coil. The lead includes a connector assembly and a ring electrode assembly, each of which are optimized for use in conjunction with conductors arranged in the form of a multifilar coil. The connector assembly takes the form of an in-line connector having a plurality of linearly arranged connecting surfaces, each coupled to one of the conductors in the multifilar coil. The ring electrode assembly is constructed such that it displays the same outer diameter as the pacing lead. In both assemblies, conductors are coupled by means of welds, rather than by crimping or swaging.
