A recently granted patent (Publication Number: US11872393B2) discloses an implantable electrode lead designed for stimulating the spinal cord. The lead comprises an outer tube, at least one electrode line, at least one electrode pole, and a stub line. The electrode lead has an elongate structure with the outer tube connectable to an active device at the proximal end. The electrode line is arranged within the outer tube, while the electrode pole, located at the distal end, is electrically connected to the electrode line for contacting surrounding tissue when implanted. The stub line extends along the outer tube parallel to the electrode line, effectively lengthening the electrode line for optimal performance.

Furthermore, the patent details various configurations and features of the implantable electrode lead, including the arrangement of multiple electrode lines and poles, the use of capacitors for electrical connections, and the design of the stub line in straight, helical, or meandering patterns. The lead is also described as being suitable for use in a system with an active device, where electrical contact elements ensure proper connectivity. The patent emphasizes the importance of achieving a specific effective line length for the electrode line to correspond to a predetermined MR excitation frequency, highlighting the innovative design and functionality of the implantable electrode lead.
