1. A medical device for providing therapy to heart tissue, comprising:
a balloon;
a movable manifold comprising a first portion comprising a first plurality of openings and a second portion comprising a second plurality of openings, the movable manifold located inside the balloon and the movable manifold configured to distribute a fluid within the balloon, wherein the movable manifold is divided along a longitudinal axis of the movable manifold to create the first portion and the second portion of the movable manifold, wherein the first plurality of openings distribute the fluid at a first flow rate and the second plurality openings distribute the fluid at a second flow rate, wherein the first flow rate and the second flow rate are different;
an elongate shaft comprising a proximal end and a distal end, the distal end of the elongate shaft being coupled with the balloon;
a central lumen, wherein the movable manifold is movably coupled with the central lumen; and
a supply lumen comprising a proximal end and a distal end, the supply lumen comprising a first portion in fluid communication with the first portion of the movable manifold and a second portion in fluid communication with the second portion of the movable manifold, wherein the supply lumen is divided along a longitudinal axis of the supply lumen to create the first portion and the second portion of the supply lumen, and wherein the supply lumen is longitudinally movable.
