Abstract
A method and device for transmyocardial revascularization using RF energy. A signal probe having a signal electrode is inserted into a myocardium. A return probe having a return electrode is placed on or within the myocardium. RF energy is supplied to the signal electrode, and forms a conductive path to the return electrode. At least one fissure within the myocardium is formed along the conductive path, allowing blood to perfuse within the fissure and revascularize the myocardium. A number of probe and electrode configurations are provided, including the use of multiple probes and electrodes, hollow probes to provide a coring effect, and pressurized fluid-supplying probes.
