Method And Apparatus For Measuring Biopotential And Mapping Ephaptic Coupling Employing A Catheter With Mosfet Sensor Array
Patent Number: US 2014/0081114 Al
Date Filed: March 20, 2014
Country Filed In: USA
Product Application: MOSFET Catheter

Description:

This invention relates generally to electro-anatomical map­ping method and an apparatus using a catheter and more particularly to a mapping catheter having an embedded MOS­FET sensor array for detecting local electrophysiological parameters such as biopotential signals within an excitable cellular matrix geometry, for determining physiological as well as electrical characteristics of conduction path and its underlying substrate within the endocardial and epicardial spaces, the arterial structure and in ganglionic plexus. The apparatus with its MOSFET sensor is geometrically config­ured as a decapolar linear array and optionally with an 8x8 sensor matrix placed on a balloon-like structure.
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.
