Abstract:
1. An implantable endocardial lead adapted for use with an implantable cardiac rhythm management device including a drug reservoir, the lead comprising: an implantable elongate lead body having a proximal end and a distal end, the proximal end configured to be connected to the implantable cardiac rhythm management device; an implantable electrode at or near the distal end for sensing cardiac electrical activities and delivering pacing pulses; a lumen within and extending through the lead body, the lumen having a proximal opening at about the proximal end and a distal opening at about the distal end, the lumen adapted to accommodate at least a portion of a flexible elongate object and to allow an end portion of the flexible elongate object to enter the proximal opening and extend from the distal opening; an implantable drug delivery device including a drug collar positioned away from the lumen at or near the distal end, the implantable drug delivery device adapted to deliver a pharmaceutical substance; a passageway extending through the implantable elongate lead body and configured to provide fluid communication between the drug collar and the drug reservoir; and a fixation helix at the distal end.
