The present invention relates to a plasma-generating device comprising an anode, a cathode, and intermediate electrodes. The intermediate electrodes and the anode form an elongate plasma channel that extends from a point between the cathode and the anode and through the anode. The plasma channel has a throttling portion with a throat having the smallest cross-sectional area of the entire plasma channel. As a plasma flow passes through the throttling portion, the plasma flows speed is increased while its pressure is decreased. By varying the position of the throttling portion in the plasma channel properties of the discharged plasma can be changed. Plasma flows with different properties can be used for various applications, especially, medical procedures.
