1. A medical electrode comprising:
- a first insulating layer;
a second insulating layer having at least one aperture therethrough; and
at least one dome-shaped conductive contact aligned with the aperture and having a rounded protrusion extending into the at least one aperture and an edge portion disposed between the first and second insulating layers, the at least one contact being adapted for contacting a surface of a patient'"'"'s brain such that friction between the rounded protrusion and the brain is effective to substantially maintain the position of the medical electrode on the brain surface.

Abstract
An implantable medical electrode supports at least one conductive contact having a rounded protrusion adapted for contacting a treatment site of a patient in use and an edge portion bordering at least a portion of the rounded protrusion. The electrode includes a first flexible insulating layer and a second flexible insulating layer having at least one aperture. In assembly, the conductive contact is positioned between the first and second insulating layers with the rounded protrusion of the contact aligned with, and extending into the aperture. In one embodiment, the rounded protrusion extends through the aperture to terminate at an apex beyond the second insulating layer.

11. A method of manufacturing a medical electrode, comprising the steps of:
-
providing a first insulating layer; providing a second insulating layer having at least one aperture therethrough; providing at least one dome-shaped conductive contact having an edge portion and a rounded protrusion; and positioning the at least one conductive contact between said first and second insulating layers so that the rounded protrusion of said at least one conductive contact is aligned with and extends into said at least one aperture of said second insulating layer, wherein said edge portion of said at least one conductive contact is disposed in contact with said second insulating layer adjacent to the at least one aperture of said second insulating layer, wherein the at least one contact is adapted for contacting a surface of a patient'"'"'s brain such that friction between the rounded protrusion and the brain is effective to substantially maintain the position of the medical electrode on the brain surface. - View Dependent Claims (12, 13, 14, 15, 16, 17)
