1. A wireless tissue ablation device comprising:
an alternating magnetic field generator;
an ablation probe comprising an ablation tip and a first electrical lead;
a catheter comprising an opening at a tissue insertion end and a lumen extending along a length of the catheter to the catheter opening, wherein the catheter comprises an electrically conductive material forming a second electrical lead; and
a magnetic field receiving coil attached to the catheter, wherein the magnetic field receiving coil is electrically coupled to the second electrical lead;
wherein at least a portion of the ablation probe is positionable within the lumen of the catheter such that a conductive circuit is completed when the first electrical lead of the ablation probe contacts the second electrical lead of the catheter during ablation, and wherein the ablation tip protrudes through the opening of the catheter.
