A method and apparatus for in vivo electroporation therapy. Using electroporation therapy (EPT) as described in the invention, tumors treated by a combination of electroporation using the apparatus of the invention and a chemotherapeutic agent caused regression of tumors in vivo. In one embodiment, the invention provides a method of EPT utilizing low voltage and long pulse length for inducing cell death. One embodiment of the invention includes a system for clinical electroporation that includes a needle array electrode having a &ldquo;keying&rdquo; element that determines the set point of the therapy voltage pulse and/or selectable array switching patterns. A number of electrode applicator designs permit access to and treatment of a variety of tissue sites. Another embodiment provides a laparoscopic needle applicator that is preferably combined with an endoscope for minimally invasive EPT.

In one embodiment, a method of EPT utilizes low voltage and long pulse length for inducing cell death. One embodiment includes a system for clinical electroporation that includes a needle array electrode having a 'keying' element that determines the set point of the therapy voltage pulse and/or selectable array switching patterns. A number of electrode applicator designs permit access to and treatment of a variety of tissue sites. Another embodiment provides a laparoscopic needle applicator that is preferably combined with an endoscope for minimally invasive EPT.
