ENERGY DELIVERY SYSTEM AND METHOD FOR PERFORMING MYOCARDIAL REVASCULARIZATION

摘要

This invention is an energy delivery system (10) for performing myocardial revascularization on a heart of a patient (12) including an energy pulse source (18) that produces energy pulses sufficient to create channels in a wall of a heart (56), an energy pulse delivery system (20) connected to receive the pulses, and deliver the energy pulses to desired location for channels in the wall (104) of the heart. Also disclosed are a sensor (14) that senses a cyclical event related to the contraction, and expansion of the beating heart (56); a controller (16) responsive to the sensor for automatically firing the energy pulse system to provide energy to strike the beating heart only within a safe time period during a heart beat cycle; RF electrical (48) or laser energy pulses; a temperature sensor (22) to avoid damage caused by overheating heart tissue; a thermal conductivity cooling system (84); and programmable adjusting duty cycle, duration, and amplitude of energy pulses.
