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.
