Abstract:
A lead assembly comprising:a lead body extending from a proximal end to a distal end defining an intermediate portion therebetween; at least one conductor disposed within the lead body and extending from a first end to a second end, the first end proximate to the proximal end of the lead body and the second end proximate to the distal end of the lead body; an electrode electrically coupled with the conductor, the electrode disposed at the second end of the conductor forming an electrode tip at the distal end of the lead body; a defibrillation coil disposed at the intermediate portion of the lead body and electrically coupled to the electrode; and at least one electrically conductive tine coupled with a portion of the lead body and positioned between the electrode and the defibrillation coil, wherein the at least one electrically conductive tine is located proximate the electrode tip at the distal end of the lead body such that when the electrode is positioned at an apex of a ventricle the at least one electrically conductive tine is located within the ventricle, wherein the at least one conductive tine is electrically insulated from the electrode.
