Method and Apparatus for Magnetically Guided Catheter for Renal Denervation Employing MOSFET Sensor Array
Patent Number: US 9,381,063 B2
Date Filed: July 5, 2016
Country Filed In: USA
Product Application: MOSFET Catheter
Description:
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.
Field of Use: The MOSFET Catheter was designed to be used in conjunction with the Catheter Guidance Control and Imaging (CGCI) system to provide physicians the ability to guide a catheter through a patient's body using a robotically-controlled magnetic guidance system. The catheter greatly improved upon eliminating the issues regarding signal to noise ratio making the MOSFET Catheter much better at being able to generate high-fidelity mapping and imaging. Initial applications for the technology were for the field of Electrophysiology and specifically for the ablation of the heart to treat patients with AFib.
