Implantable electrode lead

摘要

An implantable electrode lead for transmitting electrical impulses to excitable bodily tissue and/or for transmitting electrical signals tapped at bodily tissue to a detection unit. The electrode lead including a distal electrode, a proximal electrode connector, and an electrode supply lead which connects the electrode, or each electrode, to the electrode connector, or each electrode connector, and extends in a lead body, wherein the lead body includes a hinged alignment of hard elements.

1. An implantable electrode lead for transmitting electrical impulses to excitable bodily tissue or electrical signals tapped at bodily tissue to a detection unit or combinations thereof, the electrode lead comprising: a distal electrode; a proximal electrode contact; a lead body; and an electrode supply lead which connects the distal electrode to the proximal electrode contact and/or is used to transmit electrical shocks and/or to control sensors, and which extends in the lead body, wherein the lead body comprises a hinged alignment of closely interspaced hard elements configured and spaced for protecting the lead body and the electrode supply lead from radially acting forces and for permitting free deflection of the lead body in any direction, wherein the hinged alignment forms a rotationally symmetrical joint connection between the hard elements, wherein each hard element includes a central lumen through which the lead body and the electrode supply lead extend extends through, and wherein at least one hard element is drum-shaped and contains in an interior thereof a coil connected mechanically and electrically to the electrode supply lead, and wherein the drum-shaped element is rotatably supported on the electrode supply lead thereby enabling the lead body to rotate relative to the electrode supply lead with the coil securely placed thereon and preventing torsional stresses from forming during use of the electrode lead.
