Publication number: 20080027525Abstract: A method is provided for producing electrode structures which have a supply line and a contact surface connected thereto, wherein a planar electrode material is roll bonded onto a planar carrier material and the thickness of the electrode material and carrier material is reduced by rolling. The electrode material is then structured with formation of contact surfaces and supply lines in its surface, and predefined parts of the electrode material are removed. Then, electrode material located on the carrier material is coated with a sealing compound or a foil, and the carrier material is then removed. The structure may be used in medical implants for neuro stimulation and/or muscular stimulation, for example in a cochlear implant, a retina implant, or a cortical electrode.Type: ApplicationFiled: October 4, 2007Publication date: January 31, 2008Applicant: W.

Patent number: 6610086Abstract: A radially expandable support structure is presented, for keeping open lumina within a body, in particular a blood vessel, having a tube-shaped structure that has at least two partial structures, with a wall surface that extends between a first and a second end, which has several cut out areas, in particular, slits, which are essentially oriented parallel to the longitudinal axis of the tube-shaped structure. At least one of the partial structures (11) extend without interruption in the axial direction generally from the first end to the second end of the tube-shaped structure. A first partial structure (1, 2) can be expanded at least in the radial direction and has at least one radial-expansion component. The individual radial expansion components (12, 13) are arranged as a helix or in a helix shape. A second partial structure (11) is generally almost rigid in the axial direction.Type: GrantFiled: June 28, 1999Date of Patent: August 26, 2003Assignee: W. C. Heraeus GmbH & Co.
