18 Claims

1. A method of treatment, comprising:

inserting a vapor delivery device into a urethra of a patient, wherein the vapor delivery device includes:

a shaft; and

a distal tip, wherein the distal tip is narrower than a portion of the shaft proximal of the distal tip, wherein the portion of the shaft proximal of the distal tip defines a plurality of vapor delivery ports, and wherein the distal tip is distal to each of the plurality of vapor delivery ports;

advancing the distal tip into a bladder of the patient;

positioning the distal tip on a surface of a tissue of the bladder;

advancing the distal tip into the tissue to deform the tissue without puncturing through a thickness of the tissue; and

delivering vapor through the plurality of vapor delivery ports to the tissue to ablate the surface of the tissue.
