A method of modifying properties of intrinsic tissue of an organ is
provided. The method includes providing an organ, where a first electrode
is disposed proximal to the organ first end. The first electrode has a
surface area and insulator. A second electrode is disposed opposite the
first electrode, where the organ is disposed between the first electrode
and the second electrode. The second electrode has surface area and
surface insulator. An organ-shaping device is provided that is disposed
on the organ between the electrodes, where the organ-shaping device
deforms the organ middle section along at least one lateral direction
between the electrodes. An electric current is provided between the first
second electrodes, where a current density gradient is provided by the
electrode surface areas and the deformed organ middle section, and the
properties of the intrinsic muscle tissue are modified according to the
current density gradient.
