1. A method of gaining access into a pseudocyst, the method comprising:
delivering an electrosurgical device separate from an endoscope to a treatment site, the electrosurgical device delivered to the treatment site via a channel or lumen of the endoscope, the electrosurgical device comprising an outer elongate tubular member, an inner elongate tubular member, and a conductive tubular element disposed on an outer surface of the inner elongate tubular member, wherein an outer diameter of the conductive tubular element is greater than five French (one and two-thirds millimeters) and less than ten French (three and one-third millimeters);
electrically activating the conductive tubular element; and
creating an opening in the pseudocyst by initially cutting the pseudocyst with the electrically activated conductive tubular element and moving the electrically activated conductive tubular element into the pseudocyst while leaving the outer elongate tubular member outside of the pseudocyst, wherein the pseudocyst does not have any opening from cutting prior to the initial cutting with the electrically activated conductive tubular element.
