Abstract
A system for a mapping and ablation catheter. The catheter includes a MOSFET sensor array that provides better fidelity of the signal measurements as well as data collection and reduces the error generated by spatial distribution of the isotropic and anisotropic wave fronts and error associated with near and far field's signal averages. The system maps the change in bioelectric potential in the vicinity of an activation wave front. During measurement, the manifold carrying the sensor array translates and rotates so as to achieve a measure of high potential employing an impedance value. The system of guiding and controlling the movement of the catheter distal end is able to deliver energy for ablating the renal artery nerve and thereby providing a safe and efficient method and apparatus for neuromodulation.
