20090069704 | RAPID 3D MAPPING USING MULTIELECTRODE POSITION DATA - An electrophysiology (EP) system includes an interface for operator-interaction with the results of code executing therein. A template model can have channels positioned or repositioned thereupon by the user to define a set-up useful in rapid catheter positioning. Mapping operations can be performed without the requirement for precise catheter location determinations. A map module coordinates EP data associated with each selected channel and its associated position on the template model to provide this result, and can update the resulting map in the event that the channel or location is changed. Messaging and other dynamic features enable synchronized presentation of a myriad of EP data. Additional systems and methods are disclosed herein. | 03-12-2009 |
20090124915 | SYSTEM FOR RELOCATING CATHETER-SUPPORTED ELECTRODES ON SEGMENTED MODEL - Guidance to an operator to more accurately position electrodes upon a segmented heart model (SGM). The SGM is included in a map panel on a display screen. A catheter advanced into a beating heart supports one or more electrodes. During a single beat of the heart, an image is obtained with darkened portions corresponding to locations of the electrodes. The image is presented in the same map panel as the SGM. The current location of the electrodes is confirmed relative to the SGM, either manually or through automated software algorithms. EP data is captured that represents electrophysiological signals of the beating heart at the current location for each of the electrodes. A signal processing algorithm is applied to the captured EP data in view of the confirmed current location of the electrodes to result in a calculation that is mapped at the confirmed location of the electrodes. | 05-14-2009 |
20090204113 | High Density Atrial Fibrillatrion Cycle Length (AFCL) Detection and Mapping System - Systems and methods to assist in locating the focus of an atrial fibrillation include the association of atrial fibrillation cycle length values and statistics relating thereto with temporal locations on an electrogram of a given electrode, and/or the coordination of electrode locations with respective the spectral analyses of electrogram signals and further parameters and statistics relating thereto. Ablation therapy can proceed under guidance of such information. | 08-13-2009 |

20120078078 | MEANS FOR SECURING A CATHETER INTO A VESSEL - An electrophysiology catheter, e.g., a coronary sinus catheter, for insertion into a cardiac vessel, such as the coronary sinus, includes a handle and a catheter shaft coupled at one end to the handle. The catheter shaft has a distal end and an anchor is associated with the catheter shaft and is movable between a deployed position and a collapsed position. In the deployed position, the anchor extends radially outward from an outer surface of the catheter shaft for contacting a wall and temporarily anchoring the catheter shaft within the coronary sinus. The catheter also includes an actuator for causing deployment and collapsing of the anchor upon manipulation of the actuator. | 03-29-2012 |
