Methods and devices for performing percutaneous myocardial revascularization without disrupting the blood pump-ing activity of the heart. A percutaneous myocardial revascularization system including an active electrode disposed at the end of a catheter and a radio frequency generator coupled to the active electrode for delivering radio frequency energy thereto. Radio fre-quency energy is selectively applied to the active electrode when the active electrode is properly positioned and when the heart is not in a vulnerable stage of the cardiac rhythm.

L'invention concerne des procédés et des dispositifs pour assurer la revascularisation percutanée du myocarde sans interrompre l'activité de pompage du sang du coeur. Le système selon l'invention comprend une électrode active placée au niveau de l'extrémité d'un cathéter et un générateur de radiofréquences couplé à cette électrode pour lui fournir de l'énergie radiofréquence. Cette énergie est appliquée de manière sélective à l'électrode active lorsque cette dernière est positionnée correctement et lorsque le coeur n'est pas dans un état à risques du rythme cardiaque.
