Case description

Non-contact method of coagulation using the APC probe. APC is a non-contact thermal device. A high voltage spark is delivered at the tip of the probe, which ionizes the argon gas as it is sprayed from the probe tip in the direction of the target tissue. Argon gas is non-flammable and inexpensive to refill. It is easily ionized by the 6000 volt peak energy delivered by the tungsten wire that terminates just proximal to the probe tip. This ionized gas or plasma then seeks a ground in the nearest tissue, delivering the thermal energy with a depth of penetration of roughly 2 to 3 mm. The plasma coagulates both linearly and tangentially. By delivering energy to all tissue near the probe tip which will conduct electricity, APC can be used to treat a lesion around a fold and not clearly in view or en face.
