    Abstract: Implantable medical leads include a shield that is guarded at a termination by having a first portion and a second portion of the shield, where the first portion is between a termination of the shield at the second portion and an inner insulation layer that surrounds the filars. The first portion may reduce the coupling of RF energy from the termination of the shield at the second portion to the filars. The first and second portions may be part of a continuous shield, where the first and second portions are separated by an inversion of the shield. The first and second portions may instead be separate pieces. The first portion may be noninverted and reside between the termination at the second portion and the inner layers, or the first portion may be inverted to create first and second sub-portions. The shield termination at the second portion is between the first and second sub-portions.

    Abstract translation: 植入式医疗引线包括通过具有屏蔽件的第一部分和第二部分而在端子处被保护的屏蔽件,其中第一部分位于第二部分处的屏蔽件的终端和围绕线圈的内部绝缘层之间。 第一部分可以减少RF能量从第二部分处的屏蔽端接到丝状体的耦合。 第一和第二部分可以是连续屏蔽的一部分,其中第一和第二部分被屏蔽的反转分开。 第一和第二部分可以是分开的部分。 第一部分可以是非反相的并且位于第二部分的端接部分和内层之间,或者第一部分可以被倒置以产生第一和第二子部分。 第二部分处的屏蔽终端位于第一和第二子部分之间。
