Abstract: An electrophysiology system includes a catheter having a flexible catheter body with a distal portion; and electrodes disposed on the distal portion. The system includes a signal generator configured to generate an electrical signal by driving one or more currents between a first set of the electrodes, where a second set of the electrodes is configured to obtain an impedance measurement based on the electrical signal. A mapping processor is configured to receive the impedance measurement from the second set of electrodes; determine at least one impedance metric; and determine at least one lesion characteristic based on the at least one impedance metric.

Abstract: Methods and systems for cardiac mapping are disclosed. An example system includes a catheter shaft with one or more electrodes coupled to a distal end of the catheter shaft. Electrodes sense electrical signals at anatomical locations within a heart. A processor coupled to the catheter shaft acquires electrogram signals of the heart using the electrodes. Each electrogram signal relates to three-dimensional positional data corresponding to the anatomical locations. The processor also store the electrogram signals of the heart corresponding to electrical activities sensed at corresponding anatomical locations, calculate an activation recovery interval associated with each of the corresponding anatomical locations, determine spatial gradient data of the activation recovery interval based on a distance between at least two neighboring anatomical locations. The system also includes a display device to display a three-dimensional graphical representation of the spatial gradient data between the at least two neighboring anatomical.

Abstract: A catheter system includes a catheter comprising a tip assembly, the tip assembly having a plurality of electrodes and the plurality of electrodes are configured to measure electrical signals. The system also includes a processing unit configured to: receive a first electrical signal sensed by a first electrode of the plurality of electrodes and a second electrical signal sensed by a second electrode of the plurality of electrodes. A first vector is determined based on the first electrical signal that corresponds to the first electrode. A second vector is determined based on the second electrical signal that corresponds to the second electrode. A resultant vector is determined by summing at least the first vector and the second vector, wherein the resultant vector is indicative of the orientation of the tip assembly.

Abstract: Medical devices and method for generating multi-time scale waveforms for display of sensor measurements are disclosed. Sensed or measured output signals from a sensor, such as a catheter, are processed to generate a first data set that uses a first time scale and a second data set that uses a second time scale. The generated data sets are then displayed on a display by juxtaposing the first data set with the second data set. In this manner, measurement data from the sensor can be shown in dual time scales that allow for faster and more efficient visual diagnostic assessments.
