Abstract
A medical electrical lead, which may be useful in coupling an implantable medical device, is comprised of an elongate body having first and second spaced apart lumens. A conductor and an electrode are associated with the first lumen, and the second lumen is multi-purpose. The second lumen may be used to guide the lead and to introduce various fluids into the venous system. The second lumen may at various times be used to introduce vasodilation solutions, contrast fluids and adhesives into the venous system.
Claims25
A medical electrical lead, comprising:
- an elongated body having a proximal end portion and a distal end portion and a first lumen and a second lumen extending longitudinally therebetween, the second lumen having an opening extending to an outer surface of the medical electrical lead;
- a first electrode coupled adjacent the distal end portion of the elongated body;
- and
- a conductor extending between the proximal and distal end portions of the elongated body within the first lumen and being coupled to the electrode.
A method for positioning a medical electrical lead in a cardiac venous system, comprising the steps of:
- inserting a lead within the cardiac venous system wherein the lead includes first and second spaced apart lumens extending between a proximal end portion and a distal end portion of the lead;
- guiding the lead into the cardiac venous system using a guide element positioned in the second lumen;
- and
- introducing a fluid into the second lumen at the proximal end portion of the lead and dispensing the fluid from the second lumen adjacent the distal end portion of the lead.
