First Claim
Patent Images
1. A method for constructing an implantable medical lead comprising:
- winding one or more insulated wires around a support member to form a core, the one or more insulated wires each having first and second ends and each having a metallic core, wherein the first and second ends of the one or more insulated wires are radially extended from the support member;
coating the core with an insulating sheath such that the first and second radially extending ends of the one or more insulated wires are not coated by the sheath;
cutting the one or more insulated wires flush with the sheath to remove the first and second ends such that the metallic cores of the one or more insulated wires are exposed at the surface of the sheath; and
depositing electrically conducting material on the surface of the sheath such that the electrically conducting material is contacted with the exposed metallic cores of the one or more insulated wires at the surface of the sheath to form one or more electrode areas.

7. A method for constructing an implantable medical lead comprising:
-
coating a core comprising one or more insulated wires with an insulating sheath, the one or more insulated wires each having first and second ends and each having a metallic core, the core configured such that the first and second ends of the one or more insulated wires radially extend from the core, wherein the core is coated such that the first and second radially extending ends of the one or more insulated wires are not coated by the sheath; cutting the one or more insulated wires flush with the sheath to remove the first and second ends such that the metallic cores of the one or more insulated wires are exposed at the surface of the sheath; and depositing electrically conducting material on the surface of the sheath such that the electrically conducting material is contacted with the exposed metallic cores of the one or more insulated wires at the surface of the sheath to form one or more electrode areas. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
