Abstract: A system for use with an electrophysiological procedure is disclosed. The system includes an elongated catheter assembly having a tracking sensor and a controller. The controller is configured to track catheter assembly positions within the organ based on a plurality of electrical signals from the tracking sensor, determine a first catheter assembly position based on a first electrical and determine a second catheter assembly position based on a second electrical signal, constrain the second position with the first position, and generate an anatomical map of an organ of the electrophysiological procedure with a visualization of the catheter assembly having the second position constrained with the first position.

Abstract: A system for facilitating an ablation in a patient's heart is disclosed. The system includes a catheter and a controller. The catheter includes an electrode assembly having spaced-apart electrodes disposed on splines to generate an electric field in the heart, the splines configurable in an expanded position wherein the plurality of spaced-apart electrodes are in a selected spatial relationship, and wherein the splines are deformable relative to the expanded configuration when subjected to a force. The controller is configured to measure an electrical signal received from an electrode of the spaced-apart electrodes in response to the electric field, the electrical signal indicative of a parameter of the electric field, and the controller configured to determine a deformation of the splines relative to the expanded position based on the measured electrical signal.

Abstract: A system to generate an electroanatomical map of patient's heart is disclosed. The system includes a catheter including an electrode to detect physiological signals from within the patient's heart and a location sensor to generate location signals representative of a location of the catheter within the patient's heart, a display device, and a controller. The controller determines a catheter context characteristic based on the location signals, collects the physiological signals according to a collection parameter. The collection parameter is based on the determined catheter context characteristic. The controller further collects anatomical location signals corresponding to a measurement location associated with each of the physiological signals and generates, on the display device, a three-dimensional representation of the patient's heart based on the physiological signals and the anatomical location signals.
