Abstract
An energy delivery system for performing myocardial revascularization on a heart of a patient including an energy pulse source that produces energy pulses sufficient to create channels in a wall of a heart, and an energy pulse delivery system connected to receive the energy pulses and deliver the energy pulses to desired locations for channels in the wall of the heart. Also disclosed are a sensor that senses a cyclical event related to the contraction and expansion of the beating heart; a controller 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 or laser energy pulses; a temperature sensor to avoid damage caused by overheating adjacent heart tissue; a thermal conductivity cooling system; and programmably adjusting duty cycle, duration and amplitude of energy pulses.
