Abstract: Disclosed are devices, systems, and methods for determining the dipole densities on heart walls. In particular, a triangularization of the heart wall is performed in which the dipole density of each of multiple regions correlate to the potential measured at various located within the associated chamber of the heart. To create a database of dipole densities, mapping information recorded by multiple electrodes located on one or more catheters and anatomical information is used. In addition, skin electrodes may be implemented. Additionally, one or more ultrasound elements are provided, such as on a clamp assembly or integral to a mapping electrode, to produce real time images of device components and surrounding structures.

Abstract: 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.

Abstract: Provided herein are systems for modeling a patients cardiac electrical activity data, including at least one diagnostic catheter for insertion into the heart of the patient and a processing unit. The at least one diagnostic catheter includes at least one recording element to record patient data over multiple cardiac cycles. The patient data includes biopotential data and localization data of the at least one recording element. The processing unit includes a clustering routine that: receives the recorded patient data; segments the recorded patient data by cardiac cycle to produce segmented patient data; groups the segments based on one or more characteristics of the segments to produce segmented data groups; and combines the segmented patient data within each segmented data group to produce one or more composite recordings. The systems create one or more models of cardiac electrical activity of the patient based on the one or more composite recordings.

Abstract: A cardiac information dynamic display system comprises one or more electrodes and a cardiac information console. The one or more electrodes record sets of electric potential data representing cardiac activity at a plurality of time intervals. The cardiac information console includes a signal processor and a user interface module. The signal processor calculates sets of cardiac activity data at the plurality of time intervals using the recorded sets of electric potential data. The cardiac activity data is associated with surface locations of one or more cardiac chambers. The user interface module displays information related to the cardiac activity data. The information is presented relative to a graphical representation of surfaces of the one or more cardiac chambers.

Abstract: Provided herein are systems and methods for calculating patient information. The method includes determining a transfer matrix, recording electric potentials via a first set of recording electrodes located at a first set of recording locations to create a first set of recorded signals, and calculating patient information for a set of target locations by applying the transfer matrix to the first set of recorded signals. The transfer matrix is a characterization of electrical properties of tissue between the first set of recording locations and the set of target locations.

Abstract: Provided are a localization system and method useful in the acquisition and analysis of cardiac information. The localization system and method can be used with systems that perform cardiac mapping, diagnosis and treatment of cardiac abnormalities, as examples, and in the retrieval, processing, and interpretation of such types of information. The localization system and method use high impedance inputs, improved isolation, and relatively high drive currents for pairs of electrodes used to establish a multi-axis coordinate system. The axes can be rotated and scaled to improve localization.
