Abstract

A method of manufacturing a medical electrical lead includes molding a lead body pre-form, stringing an electrode onto the pre-form and overmolding the pre-form with a polymer to form a lead body portion. The pre-form has a proximal end, a distal end and at least one lumen extending between the proximal and distal ends. At least one asymmetric region of the pre-form has a transverse cross-section that has a non-circular outer dimension. The overmolding causes the asymmetric region to become substantially circular.
