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.

Abstract: A method of manufacture of a medical device lead. The lead includes one or more jacketed conductive elements. The jacket comprises one or more covers. The jacketed conductive element is formed by introducing a polymeric material over a conductive element, coupling the conductive element around a mandrel to form a coil shape, annealing the polymeric material over the at least one conductive element and setting a coiled shape in the at least one conductive element; and then removing the at least one conductive element from the mandrel. The coiled conductive element as manufactured thus substantially retains its original coiled shape.

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.

Prior to coupling the conductor, the second length of the wire may extend at least 270 degrees and less than 360 degrees about an axis, which is offset from an axis of the first, helical path.
