Abstract
An electrode lead for a medical implant, such as a pacemaker, has a proximal end for connection to the implant and a distal end opposite thereto having an electrode and fixation structure for holding the distal end in place relative to surrounding tissue. A distal end part at the distal end has a tape ring shape, in the form of a truncated cone, and the fixation structure forms a helical thread around the distal end part. The height of the thread is such that the crest of the thread is located within an imaginary, second truncated cone that is coaxial with the distal end part. The crest of the thread is located within an imaginary cylinder that is coaxial with the cylindrical lead body and which has the same diameter as the lead body, this imaginary cylinder intersecting the imaginary, second truncated cone.
