<p>PCT No. PCT/US97/03423 Sec. 371 Date Nov. 13, 1998 Sec. 102(e) Date Nov. 13, 1998 PCT Filed Mar. 7, 1997 PCT Pub. No. WO97/32628 PCT Pub. Date Sep. 12, 1997A neural stimulating electrode structure includes a sheet of metal foil having portions defining holes. The holes form patterns allowing the metal foil to flex without buckling when subjected to compressive forces. The holes also define discrete electrodes on the metal foil when the foil is cut. A first polymeric base layer covers a first face of the metal foil. A second polymeric base layer covers a second face of the metal foil. The first and second polymeric base layers fill the holes in the metal foil. A third polymeric base layer covers both the first and second polymeric base layers. The third polymeric base layer has portions defining pairs of holes. Each pair of holes is associated with one of the discrete electrodes. Each hole exposes a different portion of the discrete electrode for contacting tissue, passing current and/or measuring voltage.</p> |
