1. A vapor delivery device, comprising: a handle portion having a lumen and an energy coil disposed in the lumen, wherein the energy coil is connectable to a source of energy, and wherein windings of the energy coil surround and define a longitudinally extending lumen; and a cartridge portion configured to be inserted into the lumen of the handle portion, wherein the cartridge portion comprises: a shaft configured to be inserted into a urethra; a vapor delivery needle disposed in the shaft; and a vapor coil in fluid connection with (a) the vapor delivery needle and (b) a fluid source; wherein, in an assembled configuration in which the cartridge portion has been inserted into the lumen of the handle portion, the vapor coil is within the lumen of the energy coil; wherein, in the assembled configuration, an entirety of the cartridge portion is rotatable, relative to the handle portion, from a first position to a second position, by a rotational connection between the cartridge portion and the handle portion; wherein, in each of the first position of the cartridge portion and the second position of the cartridge portion, upon delivery of a fluid from the fluid source to the vapor coil, a flow of energy from the source of energy through the energy coil inductively generates vapor in the vapor coil; and wherein the lumen of the handle portion includes a proximal opening and a distal opening, and wherein a distal end of the shaft of the cartridge portion is configured to be inserted into the proximal opening in order to align and position the vapor coil within the energy coil.
