Patent ID: 8611979

Claim:
An implantable electrode lead, comprising: an elongated electrode lead body having a proximal end and a distal end, and at least one electrical supply lead enclosed by an electrically insulating material to electrically insulate the at least one electrical supply lead against the surroundings of the electrode lead, at least one electrically active surface which is disposed on the distal end, or in the vicinity thereof, and is connected to the at least one electrical supply lead, by way of which therapeutic signals can be output or diagnostic signals can be received, or both, at least one plug disposed on the proximal end, which is electrically connected to the at least one electrical supply lead and which can be connected to an electro-medical implant, and at least one preformed and/or stiffened section of the electrode lead body, which has an additional preformation and stiffening structure, by way of which the section is preformed and/or stiffened, wherein the additional preformation and stiffening structure comprises a material which is present in a first state, in which it is preformed and/or stiffened in order to preform and/or stiffen the preformation and stiffening structure, and which can be converted by degradation of the material into a second state in which the shape and/or stiffness of the material, or both and, therefore, the preformation and stiffening structure is changed compared to the first state.
