1. A medical system for applying energy to tissue, comprising:
- a handle with an elongated member detachably coupled to the handle;
an electrical source operatively coupled to a coil within the handle;
an inductively heatable structure in the elongated member and configured for positioning proximate to the coil, the inductively heatable structure comprising a flow channel therein, where the inductively heatable structure comprises a helical configuration that increases a length of the flow channel proximate to the coil;
a pump and liquid media source in communication with the flow channel in the structure, the flow channel having at least one outlet in a distal end of the elongated member;
a controller operatively coupled to the electrical source and pump;
at least one of a flow sensor, pressure sensor and temperature sensor for sending signals of an operating parameter to the controller, where the operating parameter include a first parameter, wherein the first parameter is configured to modify the tissue to permit enhanced extracellular vapor propagation therein; and
wherein the controller is configured to operate the electrical source and pump to modulate the operating parameters to inductively heat the structure to thereby convert a flow of the liquid media to a flow of vapor media in the flow channel which exits the at least one outlet to apply energy to the tissue.
