1. An apparatus for generating an electric field to treat a tumor, the apparatus comprising:
an electrical signal generator; and
a plurality of elongate elements, the plurality of elongate elements comprising at least a first elongate element and a second elongate element, wherein each elongate element of the plurality of elongate elements has:
a proximal end;
an opposed distal end; and
at least one stimulation zone,
wherein the plurality of elongate elements are coupled together at their respective proximal ends, wherein the plurality of elongate elements are selectively moveable about and between a retracted position and a deployed position,
wherein, in the retracted position, the respective distal ends of the first and second elongate elements are spaced by a first distance,
wherein, in the deployed position, the respective distal ends of the first and second elongate elements are spaced by a second distance that is greater than the first distance,
wherein the electrical signal generator is electrically coupled to the at least one stimulation zone of each elongate element of the plurality of elongate elements, and
wherein, when the plurality of elongate elements are in the deployed position, the electrical signal generator is configured to generate an alternating voltage waveform at at least one frequency in a range from 50 kHz to 500 kHz to thereby generate tumor treating fields having an intensity from about 0.1 V/cm to about 10 V/cm between the at least one stimulation zone of at least two elongate elements of the plurality of elongate elements.
