Patent ID: 7546166

Claim:
A medical lead, comprising: a lead body that extends from a proximal end to a distal end; a cardiac pacing electrode coupled to the distal end; and a pair of tissue fixation elements protruding from the lead body; wherein the pair of tissue fixation elements are adapted to be embedded within a volume of myocardial tissue to prevent migration of the lead within the myocardium and control the depth of the lead into the volume of myocardial tissue; wherein the volume of myocardial tissue comprises interventricular tissue; wherein the cardiac pacing electrode coupled to said distal end is adapted to contact the myocardium at a location spaced from the tissue fixation elements and a portion of the lead body distal to the tissue fixation elements is formed to have a J-shape; wherein a first of the pair of fixation elements protrudes from the lead body at a location between 10 and 20 millimeters from the distal end.
