A surgical ablation probe assembly particularly suitable for ablating tissue on a surface of a patient's heart having an ablation member and a stabilizing member for guiding the probe assembly to an intracorporeal location such as a surface of the patient's heart. The elongated ablation member generally has at least one ablation electrode on a distal shaft section. The stabilizing member has a vacuum lumen which applies a vacuum to the inner chamber of the stabilizing member to aspirate fluid from within the chamber or about the stabilizing member and can aid in holding the stabilizing member to an intracorporeal surface such as the epicardial or endocardial surface of the patient's heart. The probe assembly may also have a removable stylet to help retain the shape of the distal portion. The assembly is suitable for treating a patient for atrial arrhythmia, by forming linear or curvilinear lesions and preferably a continuous lesion on the surface of the patient's heart.
