Embodiment Construction

[0019] The exemplary environment 10 is in Figure 1 to Figure 4 As shown in , the exemplary environment 10 includes an exemplary system 11 for measuring and mapping cardiac activity. The system 11 includes an intracardiac catheter device 12 including: a longitudinal member 16 having a measurement device 18 and a position sensor 20 disposed thereon; and a computing device 14, although the system 11 may include other Types and / or numbers of devices, components, and / or other elements in other configurations, such as imaging devices or server devices. This exemplary technique provides many advantages, including providing a more efficient method of measuring and mapping cardiac activity for identification and treatment of abnormalities.

[0020] more specific reference figure 1 and figure 2 , the system 11 includes a longitudinal member 16 extending between a proximal end (not shown) and a distal end 22. The longitudinal member 16 is configured to be advanced into the patient a...

Abstract

A device includes a longitudinal member having a proximal end and a distal end. The longitudinal member is configured to be located proximate a tissue region within a patient. The measurement device is configured and dimensioned to be proximal to the distal end of the longitudinal member. The measurement device includes a magnetic sensor configured to measure biomagnetism and output magnetic flux data. A signal processing device is coupled to the magnetic sensor and configured to convert the output magnetic flux data into a digital representation of the output magnetic flux data. A method of measuring electrical activity using the device is also disclosed.

Description

[0001] This application claims the benefit of US Provisional Patent Application No. 62 / 912,039, filed October 7, 2019, the entire contents of which are incorporated herein by reference. technical field [0002] The present technology relates to intracardiac catheter devices and methods of use thereof, and more particularly to intracardiac catheter devices for mapping cardiac activity using magnetophysiology. Background technique [0003] Cardiac disorders, such as cardiac arrhythmias, can be treated using mapping of cardiac activity. Various techniques have been employed to provide such cardiac mapping. For example, electrocardiograms (ECGs) use electrodes to measure the electrical activity of the heart. In a typical ECG procedure, external electrodes are placed on the surface of the patient's body to measure the electrical activity of the heart from multiple angles. [0004] Alternatively, intracardiac measurements can be provided by contacting the endocardium using elect...
