Abstract
An implantable tissue-stimulating device for an implantee. The device comprising an elongate member having at least one electrode. At least a portion of the surface of the elongate member having a configuration that at least partially controls any tissue growth on and/or round the elongate member.
Claims32
An implantable tissue-stimulating hearing implant for an implantee comprising:
- an elongate member having at least one electrode, wherein at least a portion of the surface of the elongate member comprises a plurality of grooves configured to at least partially control tissue growth on and/or around the elongate member, wherein said plurality of grooves are configured to control the tissue growth such that the growth is directed to occur away from the at least one electrode.
An implantable tissue-stimulating hearing implant for an implantee comprising:
- an elongate member having at least one electrode, at least a portion of the surface of the elongate member comprising a plurality of grooves configured to at least partially control tissue growth on and/or around the elongate member, the surface further comprising a coating of a molecule adsorption promoting material deposited on the portion of the surface that at least partially controls tissue growth on and/or around the elongate member, wherein the plurality of grooves are configured to control the tissue growth such that the growth is directed to occur away from the at least one electrode.
An implantable tissue-stimulating hearing implant for an implantee comprising:
- an elongate member having at least one electrode, at least a portion of the surface of the elongate member comprising a plurality of grooves configured to at least partially control tissue growth on and/or around the elongate member, the portion of the surface of the elongate member further having a coating of a molecule adsorption promoting material that assists in at least partially controlling tissue growth on and/or around the elongate member, wherein the plurality of grooves are configured to control the tissue growth such that the growth is directed to occur away from the at least one electrode.
