Abstract

The present invention relates to a computerized system based on non-expandable catheters and electropotential guidance for fast cardiac mapping and ablation. The core components that together make up the architecture of the system are: 1) a catheter or a set of catheters that are multi-polar and non-expandable, at least one of them is steerable and suitable for catheter ablation, all of them allow contact and/or non-contact sensing of potentials from the heart muscle, 2) a multi-channel amplifier and a signal processor, 3) a computer with software and storage and optional hardware accelerator(s), 4) a pacing/driving/tracking generator, and 5) body surface electrodes. Generally speaking, these components are structured such that the catheters are placed within heart chambers or vessels, and body surface electrodes are placed on the body surface in order to pick up synchronously cardiac signals that are collected by the amplifier coupled to the catheters and body surface electrodes, catheters are located and tracked within cardiac chambers in relation to the anatomy of the heart, and the signal processor and computer storage provide data for the software. This architecture allows the system to promptly provide electrical maps on all relevant cardiac surfaces at a time (ΓΗ), including and preferably endocardial and preferably from a single beat or limited number of beats of the heart. It should be further noted that the system is based on electropotential measurements and methods of inverse solution suitable for navigation, targeting and guidance during all catheter-based electrophysiology procedures and compatible with all strategies of cardiac catheter ablation.
