An ablation probe tip (100) having a shaft (102) with an insertion end (104) and an annular aperture (120) near the insertion end (104). A center of ablation (124) is located within the shaft (102) and surrounded by the annular aperture shaft (102). The ablation probe tip (100) may be part of an ablation probe system (50) that includes an ablation source (60) that provides ablation means (62) to the ablation probe tip (100). The center of ablation (124) is a focal region from which the ablation means (62) radiates through the annular aperture (120) to form an ablation zone (150), (160), (170). The system (50) has at least one intra-operative control selected from the group of: ablation zone positioning control, ablation zone shaping control, ablation center control, ablation zone temperature control, guided ablation volume/diameter control, and power loading control. |
