    摘要: Implantable medical leads include a shield that is guarded at a termination by having a first portion and 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 surrounding 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 residing between the termination at the second portion and 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.

    摘要: Shields within implantable leads increase the torsional stiffness of the leads. The torsional stiffness may be reduced by cutting the shield axially to break the circumferential mechanical continuity of the shield. The circumferential shielding continuity of the shield may be re-established to preserve the shielding effect in various manners. The shield may overlap onto itself to close the slot created by the cut. A shield patch may be placed across the slot created by the cut. The shield may be located between two insulation layers of the lead. The shield may be cut and then the slot closed prior to application of the outer insulation layer. The outer insulation layer may then be added over the shield. The outer insulation layer may be compliant so that once covered, the circumferential mechanical continuity of the shield remains broken.
