How Does the Mitek VAPR II Electrode System Work?
Vaporization Modes (V1, V2 & V3): The increasing mode number indicates that higher maximum voltages and power outputs are available to produce a more vigorous effect. On activation, electrosurgical current heats the saline to establish a vapor pocket around the active electrode (see Photo 1). Arcs within the vapor pocket produce local vaporization of tissue. The default setting for each electrode type is designed
to deliver the minimum power necessary to sustain the vapor pocket and produce the desired tissue effect.
Desiccation Mode (DES): In this mode, the lower power settings and lower voltages across the electrode are insufficient to produce a vapor pocket. The active current is delivered to the tissue to dehydrate and coagulate without sparking or vaporization. The current then flows to the return electrode through the saline irrigant.
Blended Vaporization Modes (BV1 & BV2): Again, the increasing mode number indicates a more vigorous effect. These modes provide tissue vaporization combined with homeostasis. In BV1 mode, the output switches between the V2 and DES modes and between V3 and DES in BV2 mode.
