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: A shield layer is added to an existing lead or lead extension by applying the shield layer to the lead body between the proximal contact and distal electrode of the lead body. The shield layer may be covered with an outer insulative layer. An inner insulative layer may be applied over the lead body prior to adding the shield layer and the outer insulative layer. The shield layer may have a terminator applied to the end of the shield layer to prevent migration of the shield layer through the outer insulative layer. The shield layer may be of various forms including a tubular braided wire structure or a tubular foil. The tubular braided wire structure may be applied to the lead body by utilizing the lead body as a mandrel within a braiding machine.
Abstract translation: 通过将屏蔽层施加到引线主体的近端接触端和远端电极之间的引线体上，将屏蔽层添加到现有的引线或引线延伸部。 屏蔽层可以被外部绝缘层覆盖。 在添加屏蔽层和外部绝缘层之前，可以在引线体上施加内部绝缘层。 屏蔽层可以具有施加到屏蔽层的端部的终止器，以防止屏蔽层通过外部绝缘层的迁移。 屏蔽层可以是各种形式，包括管状编织线结构或管状箔。 管状编织线结构可以通过在编织机中利用引线体作为心轴来施加到引线体。

Abstract: A shield located within an implantable medical lead may be terminated in various ways at a metal connector. The shield may be terminated by various joints including butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. The shield may terminate with a physical and electrical connection to a single metal connector. The shield may terminate with a physical and electrical connection by passing between an overlapping pair of inner and outer metal connectors. The metal connectors may include features such as teeth or threads that penetrate the insulation layers of the lead. The shield may terminate with a physical and electrical connection by exiting a jacket of a lead adjacent to a metal connector and lapping onto the metal connector.

Abstract: The disclosure is directed to programming implantable stimulators to deliver stimulation energy via one or more implantable leads having complex electrode array geometries. The disclosure also contemplates guided programming to select electrode combinations and parameter values to support efficacy. The techniques may be applied to a programming interface associated with a clinician programmer, a patient programmer, or both. A user interface permits a user to view electrodes from different perspectives relative to the lead. For example, the user interface provides a side view of a lead and a cross-sectional view of the lead. The user interface may include an axial control medium to select and/or view electrodes at different axial positions along the length of a lead, and a rotational control medium to select and/or view electrodes at different angular positions around a circumference of the lead.

IPC: A61N1/05
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.
