1. An ablation probe comprising:
a housing configured for hand-held use, the housing comprising an onboard power source; and
a probe shaft having a proximal end coupled to the housing and a distal end opposite the proximal end, the probe shaft further comprising an ablation probe tip portion adjacent the distal end and a medial portion between the proximal end and the ablation probe tip portion;
wherein the ablation probe tip portion comprises a heating element in electrical connection with the onboard power source for heating the ablation probe tip portion, and wherein the medial portion of the probe shaft comprises a material insulative to thermal conduction;
wherein the heating element comprises an electrically resistive material applied in a pattern onto an electrically non-conductive rod portion of the ablation probe tip portion;
wherein the pattern is applied by platin or printing the electrically resistive material onto the electrically non-conductive rod portion, and laser ablating or etching a portion of the applied electrically resistive material from the electrically non-conductive rod portion; and
wherein the pattern comprises a first conductive path in electrical connection with a positive terminal of the onboard power source, a second conductive path in electrical connection with a negative terminal of the onboard power source, and a bridging portion connecting the first conductive path and the second conductive path, wherein at least one of the first conductive path and the second conductive path define an undulating wave pattern having a plurality of wave segments with alternating axially and transversely directed wave segment portions.
