A body implantable lead (10) having an electrode (30) with a thin layer (60) of a biocompatible precious metal exposed to body tissue. The electrode structure (38) is of a relatively inexpensive base metal such as titanium, which is considered biocompatible for use as a cathode. A thin layer (50) of titanium is sputtered over the distal tip of the electrode assembly. A thin outer layer (60) of a precious metal from the plantinum group is sputtered over the sputtered titanium layer. The completed electrode assembly is used in the fabrication of a body implantable lead using standard assembly practices. |
