Abstract: Conductors within an implantable medical lead that carry stimulation signal signals are at least partially embedded within a lead body of the medical lead over at least a portion of the length of the conductors while being surrounded by a radio frequency (RF) shield. A space between the shield and the conductors is filled by the presence of the lead body material such that body fluids that infiltrate the lead over time cannot pool in the space between the shield and the conductors. The dielectric properties of the lead body are retained and the capacitive coupling between the shield and the conductors continues to be inhibited such that current induced on the shield is inhibited from being channeled onto the conductors. Heating at the electrodes of the medical lead is prevented from becoming excessive.

Abstract translation: 携带刺激信号信号的可植入医疗引线内的导体至少部分地被埋在导体长度的至少一部分上，同时被射频屏蔽围绕。 屏蔽体和导体之间的空间被铅体材料的存在所填充，使得随着时间渗透导线的体液不能在屏蔽体和导体之间的空间中积聚。 保持引线体的介电性能，并且屏蔽体与导体之间的电容耦合继续被抑制，使得在屏蔽上感应的电流不被引导到导体上。 防止医疗用引线的电极的加热过度。
