Device for contacting and electrically stimulating biological tissue
First Claim
1. A device configured for at least one of contacting and electrically stimulating biological tissue by means of a plurality of electrodes, comprising:
- at least a first unit, the plurality of electrodes being provided on said first unit, said first unit being configured for implantation in a human or animal body, wherein said first unit comprises a stimulation unit configured for a retina and the plurality of said electrodes configured as stimulation electrodes, said stimulation unit comprising a multiplicity of light receiving pixel elements that convert incident light impinging on said pixel elements into electrical signals that are emitted via said stimulation electrodes,a second unit that provides a voltage supply for supplying the first unit with electrical energy,and at least a first and a second electrical conductor for connecting the voltage supply to said first unit, each electrical conductor being electrically connected to the first unit and to the second unit, said first and second electrical conductors being at different voltage potentials, and said first and second electrical conductors being embedded between two substrates,at least a first additional electrical conductor being provided and arranged spatially between the first and second electrical conductor, said first additional electrical conductor being functionally not involved in the supply of the first unit with electrical energy.

Abstract
A device for contacting and/or electrically stimulating biological tissue by means of at least one electrode has at least a first unit, on which the at least one electrode is provided and which is configured for implantation in a human or animal body, a second unit, for supplying the first unit with electrical energy, and at least a first and a second conductive track for the voltage supply of the first unit. The first and second conductive tracks are respectively electrically connected to the first and second units and are at different voltage potentials. Spatially between the first and second conductive tracks, at least a first additional conductive track is arranged that is functionally not involved in the voltage supply of the first unit.
