1. A device comprising:
at least three lumens, comprising a first lumen, a second lumen, and a third lumen, wherein the first lumen, the second lumen and the third lumen are concentrically aligned such that the third lumen is arranged as an inner lumen, the second lumen is arranged as a middle lumen, and the first lumen is arranged as an outer lumen;
a balloon inflation port in fluid communication with the first lumen;
a fluid delivery port in fluid communication with the second lumen;
a guidewire port in fluid communication with the third lumen;
a balloon in fluid communication with the first lumen, wherein the balloon has a first end and a second end;
one or more fluid delivery channels extending a length of the second lumen;
one or more fluid delivery ducts extending from the one or more fluid delivery channels to an exterior surface of the second lumen, wherein the one or more fluid delivery ducts are defined only in a portion of the second lumen that is disposed proximal to the first end of the balloon; and
a first plurality of spacers extending between the inner lumen and the outer lumen configured to maintain a structural integrity of the middle lumen, wherein the first plurality of spacers in combination with the middle lumen and the inner lumen define the one or more fluid delivery channels extending the length of the second lumen, wherein the outer lumen includes a second plurality of spacers configured to maintain a structural integrity of the outer lumen, wherein the second plurality of spacers in combination with the outer lumen and the middle lumen define a plurality of fluid delivery channels extending a length of the outer lumen.
