Abstract: An implantable segmented electrode structure may be configured to conduct electrical signals between elongated conductors of an implantable medical lead and respective portions of tissue of a patient. The implantable medical lead may extend from an implantable medical device that is implanted within the patient. The segmented electrode structure includes a plurality of separate electrode surfaces. The electrode surfaces are at a plurality of different axial positions and angular positions within the implantable segmented electrode structure. The segmented electrode structure additionally includes a plurality of prongs. The prongs extend axially from a proximal end of the segmented electrode structure through the segmented electrode structure. Each prong may electrically connect to one of the electrode surfaces. The prongs may terminate distally at respective electrode surfaces. Each prong may be configured to electrically connect to one of the elongated conductors.

Abstract: The disclosure describes a method and system that allows a user to configure electrical stimulation therapy by defining a three-dimensional (3D) stimulation field. After a stimulation lead is implanted in a patient, a clinician manipulates the 3D stimulation field in a 3D environment to encompass desired anatomical regions of the patient. In this manner, the clinician determines which anatomical regions to stimulate, and the system generates the necessary stimulation parameters. In some cases, a lead icon representing the implanted lead is displayed to show the clinician where the lead is relative to the 3D anatomical regions of the patient.

Abstract: Radiopaque markers represent that a lead is suitable for a particular medical procedure such as a magnetic resonance image scan and are added to the lead or related device. The markers may be added after implantation of the lead in various ways including suturing, gluing, crimping, or clamping a radiopaque tag to the lead or to the device. The markers may be added by placing a radiopaque coil about the lead, and the radiopaque coil may radially contract against the lead to obtain a fixed position. The markers may be added by placing a polymer structure onto the lead where the polymer structure includes a radiopaque marker within it. The polymer structure may include a cylindrical aperture that contracts against the lead to fix the position of the polymer structure. The polymer structure may form a lead anchor that includes suture wings that can be sutured to the lead.

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.

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 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.
