    摘要： A stimulation lead anchoring system includes a lead anchor and a removable inner core. The lead anchor includes an anchor body that includes a lead lumen that extends longitudinally along the anchor body and is configured and arranged to receive a portion of an electrical stimulation lead. The removable inner core includes a core body that includes an inner lumen that extends longitudinally along the core body. The lead anchor and removable inner core are configured and arranged to expand the anchor body when a portion of the core body is inserted into the lead lumen to facilitate receiving the portion of the electrical stimulation lead into the lead lumen and inner lumen and slidably positioning the lead anchor along the lead. The anchor body is configured and arranged to engage the portion of the electrical stimulation lead upon withdrawal of the core body from the lead lumen.

    摘要： A lead anchor includes a flexible housing having a first end and a second end opposite to the first end, the flexible housing defining a lead lumen forming a continuous passageway through the flexible housing. The lead anchor also includes a compressible retention ring disposed within the flexible housing and around a portion of the lead lumen. The retention ring defines an uncompressed position in which the retention ring has an elongate shape, with a major axis and a minor axis, to hold a portion of a lead received within the lead lumen. The retention ring further defines a compressed position achieved by compressing opposite ends of the major axis of the retention ring to transition the retention ring to a more circular shape that allows the lead to slidingly pass through the retention ring. Upon release of the compression, the retention ring returns to the uncompressed position.

    摘要： A fixation mechanism of an implantable lead includes a plurality of depressions of an outermost surface of the lead and a relatively flexible sleeve mounted around the outermost surface. The depressions are spaced apart from one another along a length, and each extends circumferentially, wherein a longitudinal center-to-center spacing between each adjacent depression is uniform along the length, and each depression is of substantially the same size. The sleeve has an internal surface in sliding engagement with the outermost surface of the lead, and an external surface, in which suture grooves are formed. A longitudinal center-to-center spacing between adjacent suture grooves may be substantially the same as, or a multiple of, the longitudinal center-to-center spacing between adjacent depressions of the outermost surface of the lead. The sleeve may also include a ridge protruding from the internal surface, aligned with, or offset (by center-to-center spacing of depressions) from, the grooves.

    摘要： 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.

    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.
