1. An electrically conductive lead suitable to be implanted in a human or animal body, the lead comprising:

  • a proximal end portion designed to be attached to a device, a distal end portion comprising at least one electrode member (12) for emitting and/or sensing electrical signals, an elongated body extending between said proximal end portion and said distal end portion, a drug dispensing member (26) positioned at said distal end portion and comprising a drug adapted to be released into said human or animal body, wherein the drug dispensing member (26) is located such that a part of the surface of the drug dispensing member faces the exterior of the lead, and wherein said drug dispensing member (26) is designed such that, once the lead has been implanted into said body, the amount of drug released into the body per time unit is automatically controlled to smoothly vary with time from a larger amount to a smaller amount in accordance with a predetermined relationship of the amount of drug released as a function of time.
