Claim of US Patent No. 9,931,161

1. A method of ablating tissue comprising:identifying a tissue to be ablated;
choosing a probe type configuration prior to treatment, the probe type configuration comprising at least one energy delivery probe;
displaying a placement of the at least one energy delivery probe relative to the identified tissue shown on a display unit;
inserting at least a portion of the at least one energy delivery probe into the identified tissue, the energy delivery probe including a first energy delivery member having a first handle member and a second energy delivery member having a second handle member positioned along a longitudinal axis, each handle member having a proximal end and a distal end, wherein at least a portion of the distal end of the first handle member is coupled to at least a portion of the proximal end of the second handle member, the first energy delivery member and the second energy delivery member being individually activatable;
delivering electrical energy through the at least one energy delivery probe to the identified tissue in an amount sufficient to irreversibly electroporate the identified tissue such that at least a first ablation zone is formed;
removing the first energy delivery member from the second energy delivery member after the electrical energy has been delivered through the energy delivery probe, the second energy delivery member remaining within the identified tissue; and
re-inserting at least a portion of the first energy delivery member into the identified tissue such that the first and second handle members are spaced horizontally from each other; and
delivering electrical energy through at least one of the first and second energy delivery members to the identified tissue in an amount sufficient to irreversibly electroporate the identified tissue such that at least a second ablation zone is formed.
