• a catheter shaft having a first lumen and a second lumen, the first lumen being adapted to receive at least one of a guidewire and an implanted cardiac lead, and the second lumen being adapted to receive an inflation fluid, wherein the second lumen includes a cross-sectional area at a location along a length of the catheter shaft between 0.65 mm2 and 1.90 mm2;
• and
• an inflatable balloon carried by the catheter shaft and adapted to receive the inflation fluid from the second lumen, the inflatable balloon having a working length of about 65 mm to about 80 mm, and the inflatable balloon having an inflated diameter of about 20 mm to about 25 mm.
