1. A medical vapor system comprising:
- a portable hand-held housing;
a discrete fluid conduit having an inlet, an outlet and a heating section all of which are self-contained within said portable hand-held housing, the inlet being adapted and configured to receive liquid water from a source of liquid water; and
the heating section being adapted to vaporize liquid water into water vapor flowing through the heating section based on resistive heating when a voltage difference is applied across the heating section of the fluid conduit, and said outlet being adapted and configured to be connected to a removable vapor delivery member, said removable vapor delivery member adapted to receive water vapor from said outlet;
a power supply operatively connected to apply a voltage difference from a first location of the heating section of the fluid conduit and to a second location of the heating section, thereby avoiding conduction of an electrical current and resistive heat generation outside of the heating section; and
a controller adapted to control production of water vapor by the medical vapor system.

Abstract
A medical vapor system and method is provided. The medical vapor system can include a fluid conduit having an inlet, an outlet and a heating section, the inlet being adapted and configured to be connected to a source of liquid water, a resistance heater disposed and configured to generate heat and conduct the heat to the heating section of the fluid conduit to vaporize liquid water flowing through the heating section, a power supply operatively connected to the heater, and a controller adapted to control production of water vapor by the system. Methods of use are also provided.

10. A medical vapor system comprising:
-
a fluid conduit having an inlet, an outlet and a heating section, the inlet being adapted and configured to transport a flow of liquid water to the heating section, and the heating section being a lengthwise portion of the fluid conduit and formed of an electrically conductive material; a first lead connected to a proximal section of the heating section, and a second lead connected to a distal region of the heating section; a power supply operatively connected to the heating section via the first lead and second lead to apply a voltage across the heating section to generate resistive heat along the heating section of the fluid conduit to vaporize the flow of liquid water flowing therethrough into water vapor; and a controller adapted to control production of said water vapor by the medical vapor system. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
