Patent number: 10232167Abstract: 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.Type: GrantFiled: October 23, 2014Date of Patent: March 19, 2019Assignee: Medtronic, Inc.Inventors: Vishal R Nazareth, Gregory A Boser, Lorraine R Gaunt

Patent number: 8442646Abstract: 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.Type: GrantFiled: May 17, 2010Date of Patent: May 14, 2013Assignee: Medtronic, Inc.Inventors: Kevin R.

Patent number: 8285395Abstract: 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.Type: GrantFiled: November 30, 2009Date of Patent: October 9, 2012Assignee: Medtronic, Inc.Inventors: Kevin R.
