Publication number: 20230218231Abstract: Provided is a flex-PCB catheter device that is configured to be inserted into a body lumen. The flex-PCB catheter comprises an elongate shaft, an expandable assembly, a flexible printed circuit board (flex-PCB) substrate, a plurality of electronic components and a plurality of communication paths. The elongate shaft comprises a proximal end and a distal end. The expandable assembly is configured to transition from a radially compact state to a radially expanded state. The plurality of electronic elements are coupled to the flex-PCB substrate and are configured to receive and/or transmit an electric signal. The plurality of communication paths are positioned on and/or within the flex-PCB substrate. The communication paths selectively couple the plurality of electronic elements to a plurality of electrical contacts configured to electrically connect to an electronic module configured to process the electrical signal. The flex-PCB substrate can have multiple layers, including one or more metallic layers.Type: ApplicationFiled: August 15, 2022Publication date: July 13, 2023Inventors: Derrick Ren-Yu Chou, Timothy J. Corvi, Marcus Frederick Julian, Darryl Alan Knight, Ricardo David Roman, J. Christopher Flaherty

Publication number: 20220226046Abstract: Provided herein are systems and methods for performing localization within a patient. A method of localization within a body comprises providing at least one processor coupled to at least one data storage device, establishing and calibrating a localization coordinate system within a body by executing a first localization mode by the at least one processor, recalibrating the localization coordinate system by executing a second localization mode by the at least one processor, and localizing a device within the localization coordinate system using the first localization mode and the second localization mode, by the at least one processor. The first localization mode can be an impedance-based localization mode and the second localization mode can be magnetic-based localization mode, or vice versa.Type: ApplicationFiled: June 4, 2020Publication date: July 21, 2022Inventors: Leo MARIAPPAN, Wesley D.
