Patent Images
1. A method for fabricating a neurostimulation lead, comprising:
- providing a lead body comprising a plurality of conductor wires;
providing a plurality of substantially cylindrical electrodes at a distal end of the lead body, wherein each electrode comprises a first peripheral edge at a first end of the respective electrode and a second peripheral edge at a second end of the respective electrode, wherein a plurality of notches are provided in each electrode circumferentially about the first peripheral edge;
placing at least the distal end of the lead body with the plurality of electrodes into a mold; and
injecting insulative material into the mold, wherein subsequent to the injection of insulative material, the plurality of notches facilitate the elimination of gaseous material from the insulative material promximate the corresponding electrode.
