ABSTRACT:
The improved subdural electrode for determining epileptogenic foci is of the type having two dielectric layers. The electrode includes at least one electrical lead wire having a portion of its length interposed between the dielectric layers. At least one electrode disk is interposed between the layers and has a tab formed thereon. Connection of the tab and the lead wire is by folding the outer segment of the tab toward its inward segment to crimp the wire between them. An electrically conductive circuit between the wire and the tab is thereby created. The electrical and mechanical integrity of the connection is improved by wrapping the wire about the tab several times before crimping. The connection is also improved by positioning the wrapped wire, prior to final crimping, adjacent the fold defined between the outer and inward segments.
