ABSTRACT:
A body implantable lead is provided, suitably a pacing lead for delivering pacing stimulus pulses to a patient, the lead having a fixation element such as a helix at its distal tip. The lead is provided with a soluble covering over the helix, which covering presents a smooth surface during insertion of the lead transvenously and dissolves away after a predetermined time in the patient's body, thereby exposing the anchor element. The lead is further improved by combining a radiopaque or angiographic contrast material with the protective coating, so that the physician carrying out the implantation procedure can monitor and see exactly when the coating has dissolved, whereupon the fixation element can be directly attached to the patient's heart wall.
