Abstract
A medical electrical trans-septal pacing lead includes a lead body, a tine-like structure terminating a distal end of the lead body and a distal electrode coupled to the lead body at a position proximal to and in close proximity to the structure. A method for delivering left ventricular pacing to a heart includes inserting the trans-septal pacing lead through an inter-ventricular septal wall of the heart, from a right ventricle to a left ventricle, and positioning the distal electrode in a left ventricular endocardial surface of the septal wall.

18. A method for delivering ventricular pacing to a heart, comprising the steps of:
-
passing a distal portion of a pacing lead through an inter-ventricular septal wall, from a right ventricle to a left ventricle; positioning a distal electrode coupled to the distal portion of the lead such that a portion of the distal electrode is located within a left ventricular endocardial surface; and delivering pacing pulses via the distal electrode. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
