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.
摘要翻译：一种心脏起搏引线，具有排列成多线圈的多个独立绝缘导体。引线包括连接器组件和环形电极组件，每个连接器组件和环形电极组件被优化用于与以多线圈形式布置的导体结合使用。连接器组件采用具有多个线性布置的连接表面的在线连接器的形式，每个连接表面连接到多针线圈中的一个导体。环形电极组件被构造成使得其显示与起搏引线相同的外径。在两个组件中，导体通过焊接而不是通过压接或模锻连接。

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 lead for delivering electrical signals to and/or receive electrical signals from a human heart that includes a solid inner conductor, and a fixation device having a titanium nitride coated surface and electrically coupled to the inner conductor. A steroid is applied to the titanium nitride surface of the fixation device, and at least one layer of insulation is positioned around the inner conductor. A conductive coil is positioned around and is insulated from the inner conductor, an electrode ring electrically coupled to the conductive coil is positioned around and is electrically isolated from the inner conductor, and an insulating spacer is positioned between and electrically isolates the ring electrode and the fixation device.

摘要： An introducer catheter used to deliver an endocardial cardiac electrode has a stylet lumen which collapses upon removal of the stylet to allow for more clearance for the lead and connector to pass when the catheter is removed after lead placement. The collapsible stylet lumen permits the introducer catheter size to be reduced to 8 or 9 French and provide for passage of a 4 French lead.
