Abstract
A non-implantable minimally invasive system for treatment of tissue in a body via direct current ablation is provided. A low-corrosion electrode for use with such system is further provided. In one embodiment the electrode includes a catheter end configured for coupling to a catheter, a tip configured for puncturing the tissue, and a length extending between the catheter and the tip. The length includes an active portion and an insulated portion. The active portion is electrically conductive and is between approximately 3 mm and approximately 12 mm long at an inserted portion of the electrode. The length further comprises an inner core formed of a material having a high resistance to deformation and an outer shell formed of a material having a high resistance to material decomposition.
