Margin extension device and method

A treatment system comprising:

• a control module, wherein the control module is configured to generate at least one electrical pulse configured to electroporate a cancer cell;
• a surgical margin extender comprising:
• an anode;
• a cathode;
• and
• a contact member electrically connecting the anode and cathode in a configuration such that the anode and the cathode can electroporate the cancer cell via the transmission of the at least one pulse to a living tissue, wherein the contact member is a planar structure that forms a cylindrical insert by rolling a first end region of the contact member to overlap a second end region of the contact member;
• and
• leads connecting the anode and the cathode to the control module.

A method of treating a cancer, the method comprising:

• identifying the location for providing a treatment;
• applying a surgical margin extender to tissue at the treatment location, wherein the margin extender comprises:
• an anode;
• a cathode;
• and
• a contact member, wherein the contact member comprises a conductive material that electrically connects the anode and the cathode;
• and wherein the contact member electrically connects the anode and cathode at a distance such that the anode and the cathode can electroporate the cancer cell;
• rolling the contact member to form a cylindrical insert and inserting the cylindrical insert into a void defined by the tissue, wherein the contact member has a first end region and an opposed second end region, and wherein the first end region overlaps the second end region;
• applying an electrical current to the contact member via the anode and cathode, wherein the application of the electrical current to the contact member via the anode and the cathode electroporates a cancer cell at the treatment location.
