Abstract
A near-field antenna structure is described that is an effective delivery tool for radiofrequency (RF) and microwave power to achieve coagulative necrosis in metastatic tumors while reducing or eliminating thermal conduction along the structure. This tool is a probe small enough to be used safely virtually anywhere in the neck, chest, abdomen, and pelvis, and be guided by computerized tomography (CT) or ultrasonic imaging.
Claims3
A catheter comprised of one or more sections resonant at a drive frequency, the sections being conjoined with non-conductive materials to enable efficient passage of electromagnetic power at the drive frequency but inefficient passage of power at other frequencies or thermal energy.
