Abstract
Methods, systems and devices for applying energy to tissue, and more particularly relates to a system for ablating or modifying structures in a body with systems and methods that generate a flow of vapor at a controlled flow rate for applying energy to the body structure
Claims25
A method for a controlled treatment of a body structure, the method comprising:
- positioning a working end of a vapor delivery system at a targeted site in a body;
- providing a flow of liquid media at a selected fluid flow rate in the system and converting the liquid media to vapor media where a vapor flow rate corresponds to the selected fluid flow rate;
- and
- delivering the vapor media to the targeted site for a selected time interval thereby providing a controlled amount of energy to the targeted site.

A medical method for treating body structure, comprising:
- providing a vapor delivery system including a flow channel and energy applicator for applying energy to a flow of liquid media in the flow channel;
- introducing a first flow of liquid media at a first liquid flow rate into the flow channel and converting the liquid media to vapor media, wherein a first vapor flow rate is configured for at least one of pre-heating and maintaining heat in the flow channel;
- and
- introducing a second flow of liquid media at a second liquid flow rate into the flow channel and converting the liquid media to vapor media, wherein second vapor flow rate is configured for exiting at least one vapor outlet for applying energy to the body structure.

A medical system for applying energy to tissue, comprising:
- a handle with an elongated member coupled to the handle;
- an electrical source operatively coupled to a coil within the handle;
- an inductively heatable structure positioned proximate to the coil;
- a pump and liquid media source in communication with a flow channel in the structure, the flow channel having an 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 operating parameters to the controller;
- and
- wherein the controller is configured to operate the electrical source and pump at selected 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.

A method for delivering energy to body tissue, comprising:
- introducing a working end of a vapor delivery probe into a targeted site in tissue;
- providing a flow of a condensable vapor under first operational parameters from the working end to modify the targeted site to permit enhanced extracellular vapor propagation therein;
- and
- providing a flow of the condensable vapor under second different flow parameters from the working end to cause cell death in the targeted site.
