A kit comprising an ablation catheter, the ablation catheter comprising: an elongate catheter body with a lumen within, a proximal end, and a distal end; a first inline chamber having an elongate body, a lumen within, a proximal end, and a distal end, wherein said lumen of said first inline chamber is in fluid communication with said lumen of said elongate catheter body; a second inline chamber having an elongate body, a lumen within, a proximal end, and a distal end and configured to contain a fluid, wherein said lumen of said second inline chamber is in fluid communication with said lumen of said first inline chamber; an occlusion member positioned between the first inline chamber and the second inline chamber and configured to control a flow of fluid from said second inline chamber to said first inline chamber; at least one delivery port at said distal end of said catheter body; a first inflatable balloon positioned on said catheter body distal to said at least one delivery port; and a second inflatable balloon positioned on said catheter body proximal to said at least one delivery port; wherein said first and second inflatable balloons are configured to position said catheter body within a hollow organ of a patient, further wherein pressure applied to said fluid in said second inline chamber causes said occlusion member to open to allow said second inline chamber to deliver said fluid to said first inline chamber where said fluid is converted to vapor therein, wherein said first inline chamber is configured to provide said vapor to said catheter body and said catheter body is configured to allow said vapor to exit said at least one delivery port to ablate a target tissue. an elongate catheter body with a lumen within, a proximal end, and a distal end; a first inline chamber having an elongate body, a lumen within, a proximal end, and a distal end, wherein said lumen of said first inline chamber is in fluid communication with said lumen of said elongate catheter body; a second inline chamber having an elongate body, a lumen within, a proximal end, and a distal end and configured to contain a fluid, wherein said lumen of said second inline chamber is in fluid communication with said lumen of said first inline chamber; an occlusion member positioned between the first inline chamber and the second inline chamber and configured to control a flow of fluid from said second inline chamber to said first inline chamber; at least one delivery port at said distal end of said catheter body; a first inflatable balloon positioned on said catheter body distal to said at least one delivery port; and a second inflatable balloon positioned on said catheter body proximal to said at least one delivery port; wherein said first and second inflatable balloons are configured to position said catheter body within a hollow organ of a patient, further wherein pressure applied to said fluid in said second inline chamber causes said occlusion member to open to allow said second inline chamber to deliver said fluid to said first inline chamber where said fluid is converted to vapor therein, wherein said first inline chamber is configured to provide said vapor to said catheter body and said catheter body is configured to allow said vapor to exit said at least one delivery port to ablate a target tissue.
