Abstract
An active fixation coronary sinus lead apparatus includes electrode support means which include an electrode support longitudinal axis. A plurality of electrode segments are supported by the electrode support means and are arrayed around the electrode support longitudinal axis. A plurality of insulation segments are supported by the electrode support means and are arrayed around the electrode support longitudinal axis at positions opposite to the electrode segments. In this respect, the insulation segments are interspersed between the electrode segments. Electrode segment orientation means are connected to the electrode support means for selectively orienting the electrode segments and the insulation segments around the electrode support longitudinal axis. Vessel anchoring means, which can include three flexible anchor wing portions, are connected to the electrode support means for anchoring the apparatus to an interior wall of a blood vessel. A pressure monitoring system can be connected to the vessel anchoring means for monitoring pressure inside the anchoring means.

16. A method for applying a voltage to a proximal portion of an interior wall of an anatomical structure which also includes a distal interior wall portion, comprising the steps of:
-
obtaining an electrode lead apparatus which includes an electrode segment arrayed around an electrode support longitudinal axis and which includes an insulation segment arrayed around the electrode support longitudinal axis at a position opposite to the electrode segment, positioning the electrode lead apparatus inside the anatomical structure, such that the electrode segment is adjacent to the proximal interior wall portion and located opposite to the distal interior wall portion, and energizing the electrode segment adjacent to the proximal interior wall portion, such that distal interior wall portion is not energized. - View Dependent Claims (17, 18, 19)
