Abstract
The invention is directed to an intracorporeal device for myocardial revascularization of a patient's heart tissue by at least one burst of RF energy over an interval of about 1 to about 500 msec, preferably about 30 to about 130 msec. The intracorporeal device has an elongated insulated, electrical conducting shaft with an uninsulated distal tip which is configured to emit RF energy. The uninsulated distal tip has a diameter of about 0.025 to about 0.2 inch, preferably about 0.04 to about 0.08 inch and a length of about 0.1 to about 5 mm, preferably about 1.5 to about 3.5 mm.
