Title:
LEADS CONTAINING SEGMENTED ELECTRODES WITH NON-PERPENDICULAR LEGS AND METHODS OF MAKING AND USING
Document Type and Number:
WIPO Patent Application WO/2014/193762
Kind Code:
A3
Abstract:
A method of making an electrical stimulation lead method includes attaching a pre-electrode to a lead body. The pre-electrode is a single, unitary, undifferentiated construct with a ring-shaped exterior. The method further includes attaching a plurality of conductor wires to the pre-electrode; and, after coupling to the lead body, removing an outer portion of the pre-electrode to separate remaining portions of the pre-electrode into a plurality of segmented electrodes spaced around the circumference of the lead body. When separated, each of the segmented electrodes includes a body and at least one leg extending inwardly from the body. The body defines an external stimulating surface and each of the at least one leg has an outer surface. For at least one of the at least one leg, the outer surface of the leg forms a non-perpendicular angle with the external stimulating surface of the body.
