Claim 12:
13. 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 slidably 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 supply at least one current to the solenoid actuator, wherein the supply of the at least one current simultaneously causes (a) the first winding to generate a first magnetic field having a first polarity, and (b) the second winding to generate a second magnetic field having a second polarity, wherein the first polarity is opposite to the second polarity, wherein the first magnetic field shares a polarity with the magnet, and wherein the second magnetic field has a polarity opposite to a polarity of the magnet.
