A vapor delivery device includes an induction coil system. The induction coil system can include a coiled fluid tube, a coiled wire, a capsule between the coiled fluid tube and the wire, and a cooling fluid supply configured to force a cooling fluid through the capsule across the coiled wire. The induction coil system can include a closed loop ferrite core, a wire coiled around a first portion of the ferrite core, and a fluid tube coiled around a second portion of the ferrite core. A wire coil can be contained in a cartridge system removably coupleable to a disposable vapor delivery device. The system can include a fluid flow controller and induction power regulation to maintain a specific operating pressure range for vapor within a uterus or other bodily cavity, tract, or duct.
