  • Medical lead with filler layer
    Patent number: 9014816
    Abstract: A medical lead includes a first wire coil having an outer diameter and a marker coil having an inner diameter. The marker coil is assembled over the first wire coil. The outer diameter first wire coil is smaller than the inner diameter of the marker coil thereby defining a gap. A second wire coil substantially fills the gap between the first wire coil and the marker coil. A ball weld is formed at an end of the medical lead adjacent each of the first and second wire coils and adjacent the marker coil.
