Abstract:
1. A method of forming a medical lead comprising: forming a first wire coil with a first outer diameter and having an end; removing a coating from a distal section at the end of the first wire coil thereby creating a second outer diameter in the distal section, the second outer diameter being less than the first outer diameter; forming a second wire coil over at least the second outer diameter of the distal section of the first wire coil thereby filling an area around the second outer diameter of the first wire coil in the distal section and at the end of the first wire coil; forming a marker coil over the first and second wire coils at least over the distal section and at the end of the first wire coil and the end of the second wire coil; and forming a single ball weld at a distal end of the medical lead where the ends of each of the first and second wire coils and the marker coil are coupled creating an electrical coupling.
