Abstract

An integrated multiple energy ablation system that allows for a variety of ablation procedures to be performed without the interchanging of catheters. A console is provided that is connected to one or more energy treatment devices such as catheters or probes, via an energy-delivering umbilical system. A processor in the console allows a user to selectively control which type of energy is released into the umbilical system and delivered to the energy treatment devices. Cryogenic fluid, RF energy, microwave or direct current as well as laser energy can be supplied in order to cover a wide range of ablation techniques. The integrated ablation station is designed to be compatible with commercial catheters and allows for sequential or simultaneous ablation and mapping procedures to be performed when a deeper and wider lesion capability and/or a broader temperature ablation spectrum is desired.
