1. An expandable energy delivery assembly adapted to deliver energy to tissue, the assembly comprising:
an elongate device comprising a wall defining an irrigation lumen therethrough and an irrigation port extending across a thickness of the wall, the irrigation port being proximal to a distal end of the elongate device;
an inflatable element secured to the elongate device such that the irrigation port is disposed within a fluid chamber defined by the inflatable element; and
an electrode disposed on the inflatable element,
wherein the inflatable element defines at least one irrigation aperture in fluid communication with the irrigation port and adapted to allow cooling fluid to pass from within the fluid chamber to outside the inflatable element, and
wherein the at least one irrigation aperture is sized to maintain a pressure of the cooling fluid within the inflatable element between about 0.5 atm and about 4 atm when a substantially constant irrigation flow rate of the cooling fluid from a fluid source into the inflatable element is between about 5 mL/min and about 15 mL/min.
