1. A port apparatus for use for providing electrocautery for surgery on a site of a subject, said device comprising:
an expandable sheath device, wherein said expandable sheath device having a distal portion and a proximal portion separated longitudinally from one another, wherein said expandable sheath has a tip at said distal portion;
a diode disposed on said distal portion of said expandable sheath device, wherein position of said diode is longitudinally spaced from said tip of said expandable sheath toward said proximal portion of said expandable sheath;
an electro-surgical terminal disposed on said proximal portion of said expandable sheath device;
a wire disposed longitudinally on said expandable sheath device, wherein said wire is in communication with said diode and said electro-surgical terminal;
a trocar device, wherein said expandable sheath device is configured to receive said trocar device that extends longitudinally through said expandable sheath;
a dilator, wherein said trocar device is configured to receive said dilator that extends longitudinally through said trocar device; and
said expandable sheath is configured to expand radially outward into an expanded state upon receiving said trocar device that has a radius larger than the radius of said expandable sheath in an unexpanded state.
