1. A prostate treatment device, comprising:
an introducer shaft:
a vapor generator configured to generate a condensable vapor;
a vapor delivery needle in communication with the vapor generator and movably disposed within the introducer shaft;
a magnet attached to the needle;
a solenoid actuator disposed around the magnet, wherein the solenoid actuator comprises a first winding and a second winding; and
a power supply configured to simultaneously supply a first current to the first winding and a second current to the second winding in order to move a distal tip of the vapor delivery needle between a retracted position inside the introducer shaft and an extended position at least partially outside of the introducer shaft, wherein the first current is in a first direction opposite to a second direction of the second current, wherein the first winding is configured to generate a first magnetic field when the first current is applied to the first winding, and wherein the second winding is configured to generate a second magnetic field when the second current is applied to the second winding.
