Abstract: 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.

Abstract: A medical lead may be fabricated using an electrode fixture ((130A)-(130D)) configured to facilitate circumferential and axial alignment between electrodes of the lead. In one example, a method includes positioning an electrode fixture around at least one conductor of a plurality of conductors (122) for a medical lead, wherein the electrode fixture at least partially retains an electrode assembly. The method also includes electrically coupling a portion of the at least one conductor with at least a portion of the electrode assembly at an attachment area defined by the electrode assembly when the electrode assembly is at least partially retained by the electrode fixture.
