Abstract

An implantable medical lead for transmitting electrical pulses to excitable bodily tissue and/or signals detected at bodily tissue to a detection and evaluation unit, including a distal electrode or a distal sensor, or actuator; a proximal electrode connector or sensor/actuator connector; and a lead pole which connects the electrode or the sensor or actuator to the electrode connector or sensor/actuator connector and extends in the lead body, wherein the lead pole comprises at least two separate and individually insulated conductors which are electrically interconnected at least at one point which functions as an interchange point, or reversal point, in the lead extension from the proximal electrode or sensor connector to the distal electrode or the distal sensor, and wherein at least one of the separate conductors, in particular close to the reversal point, is interrupted at least once and/or is not connected at one end.
