HIGH RESOLUTION ELECTRO-ANATOMIC MAPPING USING MULTIPLE BIOPOTENTIAL SENSORS AND ASSOCIATED SIGNAL PROCESSING AND DIGITIZATION IN THE CATHETER TIP

摘要

An apparatus for sensing an electrophysiological biopotential signal in combination with an external control circuit includes a catheter having a tip portion, an analog front-end sensor array in the tip portion of the catheter communicated with at least a first electrode in the tip portion of the catheter, and an analog signal processing integrated circuit in the tip portion of the catheter communicated with analog front-end sensor array.
