  • Patent number: 10232167
    Abstract: An implantable electrode for electrical stimulation of a body, for example, being a component of an implantable medical electrical lead, is preferably in the form of a coiled conductor wire, wherein the wire is formed by a tantalum (Ta) core directly overlaid with a platinum-iridium (Pt—Ir) cladding. When a maximum thickness of the Pt—Ir cladding defines a cladded zone between an outer, exposed surface of the electrode and the Ta core, a surface of the Ta core encroaches into the cladded zone by no more than approximately 50 micro-inches. The tantalum core may be cold worked to improve surface quality or formed from a sintered and, preferably, grain stabilized tantalum.

  • Publication number: 20170312500
    Abstract: An implantable medical electrical lead includes an electrode assembly in which an electrical junction between a first conductor and an inner surface of a first electrode of the assembly is wedged within a first channel of at least one core member of the assembly, around which the first electrode extends. The at least one core member is formed from an insulating material, and the first channel may be one of a plurality of longitudinally extending channels arrayed around a circumference of a central lumen of the assembly, which is defined by the at least one core member. The first conductor extends along a length of the assembly, for example, defined between the first electrode and a second electrode thereof, in a helical path that travels around the central lumen.

  • Patent number: 8442646
    Abstract: An inner surface of a coupling component sidewall forms first and second portions of a cavity of the coupling component. A conductive coupling between an electrode and a conductor of a medical electrical lead may be formed by inserting a segment of the conductor into the first portion of the cavity, crimping the sidewall of the coupling component around the inserted segment, inserting a segment of the electrode into the second portion of the cavity, and welding an edge of the sidewall to the inserted electrode segment. The edge of the sidewall may define a slot, extending between first and second portions of the cavity, or a hole extending through the sidewall. The electrode may be part of an electrode assembly, mounted around an inner insulation layer of the lead, and the conductor may be part of a conductor assembly extending between inner and outer insulation layers of the lead.

  • Patent number: 8285395
    Abstract: The present invention is configured to provide an offset weld and crimp in a coupling component that can be located entirely within a lumen of a lead body. This end is accomplished by providing an asymmetric coupling component is provided with a crimp recess, for example a groove or a bore extending along one side of the component and a thickened portion offset laterally from the groove or bore and having a welding surface displaced laterally from the groove or bore. While the embodiments illustrated herein are those employing a crimping groove, for purposes of understanding the invention it should be understood that a bore may be substituted. In preferred embodiments, the crimp recess is used to receive a stranded or cabled conductor within the lead body and the offset portion is used to attach to one or more filars of an electrode coil by welding thereto.
