Abstract
A method for treating a patient by covering a tissue region with a electric field capable of transiently or permanently permeabilizing cells in said tissue region, comprising the steps of: a. positioning the electrodes of an electrode device in a tissue region to be treated; and b. creating a specific polarity pattern by applying to a first subset of electrodes comprising at least two electrodes a first polarity while at the same time applying to a second subset of electrodes comprising at least two electrodes a second polarity.

A method for treating a patient by covering a tissue region with an electric field capable of transiently or permanently permeabilizing cells in said tissue region, comprising the steps of:
- a. positioning the electrodes of an electrode device in a tissue region to be treated;
- and
- b. creating a specific polarity pattern by applying to a first subset of electrodes comprising at least two electrodes a first polarity while at the same time applying to a second subset of electrodes comprising at least two electrodes a second polarity.
A treatment system for the treatment of cancers and other diseases, comprising:
- a pulse generating device;
- a switching device;
- and
- an electrode device with a symmetry axis, wherein the devices are in operative connection, the electrode device comprises at least two electrodes for placement on a tissue region to be treated and for creation of a specific polarity pattern, wherein the switching device is adapted to assign a specific polarity to each of the electrodes, wherein the switching device is adapted to activate and deactivate the electrodes so as to define a treatment volume of variable dimensions and geometry.
