CORONARY SINUS/CARDIAC VEIN PACING LEAD USING A MULTI-PURPOSE SIDE LUMEN

摘要

A medical electrical lead (200), which may be useful in coupling an implantable medical device, is comprised of an elongate body having first (206) and second (202) spaced apart lumens. A conductor (208) and an electrode (212) 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.
