Balloon catheter methods of use

A method of using a catheter for dilating an area of the esophagus, comprising:

• providing a substantially deflated balloon having an inflated cross-section that is at least partially oblong;
• positioning the balloon in an upper esophagus area of a patient;
• inflating the balloon to an inflated state wherein the cross-section is at least partially oblong;
• deflating the balloon;
• and
• removing the balloon from the upper esophagus area of the patient.

A balloon catheter kit comprising:

• a first balloon assembly comprising:
• a first balloon having a first lumen fluidly coupled to a first hub to selectively transition the first balloon between a deflated state and an inflated state;
• wherein, in the inflated state, the first balloon has an oblong cross-section with a first circumference;
• a second balloon assembly comprising:
• a second balloon having a second lumen fluidly coupled to a second hub to selectively transition the second balloon between a deflated state and an inflated state;
• wherein, in the inflated state, the second balloon has an oblong cross-section with a second circumference;
• a container configured to removably contain both the first balloon assembly and the second balloon assembly;
• further wherein both the first balloon assembly and the second balloon assembly are sized to pass over a guidewire.
