DEVICE WITH A BASE BODY
First Claim
1. A device having a base body, at least one electrode being arranged on said base body, wherein said electrode is arranged for exchanging electrical or chemical signals with surrounding tissue, said at least one electrode is covered by a protective layer,wherein the protective layer is made from material of such a nature that, after contact with the tissue, decomposes in a defined manner and at least to such an extent that said at least one electrode comes into direct contact with said tissue.

1. A device having a base body, at least one electrode being arranged on said base body, wherein said electrode is arranged for exchanging electrical or chemical signals with surrounding tissue, said at least one electrode is covered by a protective layer,
wherein the protective layer is made from material of such a nature that, after contact with the tissue, decomposes in a defined manner and at least to such an extent that said at least one electrode comes into direct contact with said tissue.
- 13. An active retinal implant comprising a multiplicity of image cells that convert incident light into electrical signals, a base body, a multiplicity of electrodes being arranged on said base body, wherein said electrodes are arranged for delivering said electrical signals to tissue surrounding said retinal implant when in use, said multiplicity of electrodes being covered by a protective layer, said protective layer being made from such a material that, after contact with the tissue, decomposes in a defined manner and at least to such an extent that said electrodes come into direct contact with said tissue.
- 18. A method for protecting, during implantation into a tissue, an electrode arrangement which is provided on a base body of a device and which is arranged to exchange electrical or chemical signals with surrounding tissue, said electrode arrangement being embedded in a protective layer, wherein the protective layer is made of such a material that, after contact with the tissue, decomposes in a defined manner and at least to such an extent that the electrode arrangement comes into direct contact with the tissue.
- 21. A method for establishing contact between a tissue and an electrode arrangement which is provided on a base body of a device, said electrodes having tips and being arranged for exchanging electrical or chemical signals with the surrounding tissue, said electrode arrangement being embedded in a protective layer, wherein the protective layer is made of such a material that, after contact with the tissue, is decomposed in a controlled manner, such that the tips of the electrode arrangement come into contact with the tissue and gradually penetrate into the latter.
