ABLATION PROBE FIXATION
An ablation probe fixation apparatus for securing an ablation probe to tissue includes a base having a top surface and a skin-contacting bottom surface, wherein the base includes an adhesive layer disposed on the skin-contacting bottom surface. The fixation apparatus also includes a fixation member coupled to the top surface of the base. The base and the fixation member include an aperture defined therein for insertion of the ablation probe therethrough.
