Lead with septal defibrillation and pacing electrodes
First Claim
1. An endocardial defibrillation lead comprising:
- a lead body having a distal end for positioning within a patient'"'"'s heart and a proximal end for connection to an implantable pulse generator;
a defibrillation electrode positioned on said lead body near said lead body distal end;
a securable septal pacing electrode positioned on said lead body proximal of said distal end of said lead body for securing said defibrillation electrode to the intraventricular septum of said patient'"'"'s heart; and
means disposed at said distal end for securing said distal end to a separate portion of said patient'"'"'s heart.

Abstract
A lead system for use with an implantable pacemaker/cardioverter/defibrillator. The lead system includes a securable pace/sense electrode positioned between the distal tip of the lead and the tricuspid valve. The distal tip of the lead is positioned at the apex of the right ventricle and may or may not be secured there by a second fixation means such as a screw tip or tines. The securable pace/sense electrode allows the defibrillation electrode to be accurately positioned by the patient'"'"'s surgeon and maintained in intimate contact with the septum wall of the patient'"'"'s heart, thereby reducing defibrillation thresholds; it provides a sense signal from the region of the His bundle or AV node, which can be used with other electrodes to distinguish between various arrhythmias; and it provides more physiologic pacing leading to greater cardiac output.
