Implantable medical leads and methods of making. The method includes providing first and second tubes, and arranging a segment of the first tube side-by-side with a segment of the second tube along a region of interface. The tubes are forced to a non-linear shape along at least a portion of the region of interface. An adhesive is applied to the portion of the region of interface and cured. Upon curing, the adhesive bonds the tubes to one another and elastically maintains the non-linear shape in the absence of an external force. A conductive element is disposed within at least one of the tubes. In some embodiments, the non-linear shape is a sigmoid shape, and the method includes arranging the tube segments in a fixture having a structure defining the sigmoid shape.
