IMPLANTABLE CANCER THERAPY ELECTRODES WITH REDUCED MRI ARTIFACTS

Embodiments herein relate to implantable cancer therapy electrodes with reduced magnetic resonance imaging artifacts. In an embodiment, a lead for a cancer treatment system can include a lead body with a proximal end and a distal end and defining a lumen, and one or more electric field generating electrodes, wherein the one or more electric field generating electrodes can be disposed along a length of the lead body. The one or more electric field generating electrodes include a ribbon wire with a thickness of the ribbon wire in a radial direction with respect to the lead body of less than 0.005 inches, or a walled tube with a thickness of the walled tube less than 0.005 inches, or a sputter coating with a thickness of the sputter coating in a radial direction with respect to a lead body of less than 0.005 inches. Other embodiments are also included herein.
