    Abstract: Implantable medical leads include a conductive interconnect within a high frequency shunt that dissipates high frequency current. The conductive interconnect provides an elasticity that allows a drive shaft to rotate and translate during implantation of the lead while the conductive interconnect maintains physical contact with the drive shaft and with a shunt electrode before, during, and after the implantation. The conductive interconnect may provide a low friction that presents a smooth rotation and translation of the drive shaft to provide an acceptable tactile feedback during implantation. The conductive interconnect also provides a high electrical conductivity so that a substantial amount of high frequency current flows through the conductive interconnect to the shunt electrode. The conductive interconnect may include a polymer filler that partially penetrates into the interstitial spaces of the conductive interconnect to assist in maintaining the physical integrity of the conductive interconnect.

    Abstract translation: 可植入医疗引线包括高频分流器内的导电互连，消散高频电流。 导电互连提供弹性，其允许驱动轴在引线注入期间旋转和平移，而导电互连在植入之前，期间和之后与驱动轴和分流电极保持物理接触。 导电互连可以提供低摩擦，其提供驱动轴的平滑旋转和平移，以在植入期间提供可接受的触觉反馈。 导电互连还提供高导电性，使得大量的高频电流流过导电互连到分流电极。 导电互连可以包括部分地渗透到导电互连的间隙空间中以有助于维持导电互连的物理完整性的聚合物填料。

    Abstract: Methods, systems, and devices for enhancing the efficiency and efficacy of energy delivery and tissue mapping. One system includes a treatment element having a plurality of electrodes and an energy generator that is configured to deliver electric energy pulses to the electrodes in a variety of patterns. For example, electrodes may be arranged in closely spaced pairs. The energy generator may deliver mapping energy to each electrode in each pair individually to map tissue and may deliver ablation energy to the electrodes in each pair together, such that each pair is treated like a single electrode, to deliver ablation energy, such as bipolar ablation energy between adjacent pairs. One system includes at least one concave electrode, the configuration of which concentrates the energy and drives it deeper into the tissue. One system includes neutral electrodes between active electrodes, the energy generator selectively coupling the neutral electrodes to alter the ablation pattern.
