    Abstract: An electrode support structure has a guide body (12) having a distal end and a stylet (80) having a bendable portion extending along an axis outside the distal end of the guide body (12). The structure also includes at least one flexible spline leg (22) having a body and a far end extending beyond the distal end of the guide body (12) and attached to the bendable portion of the stylet (80). The spline leg (22) is normally flexed between the distal guide body end and the bendable stylet portion in a first direction that extends along and radially outward of the axis of the stylet (80). At least one electrode element (28) is on the flexible spline leg (22). The bendable stylet portion (80) applies tension to flex the spline leg (22) in a second direction.

    Abstract: Systems (10) and methods examine heart tissue morphology for the purpose of locating a potential ablation site. The systems and methods derive the electrical characteristic of tissue lying between the electrode pairs (38) based, at least in part, upon sensing tissue impedances. The systems and methods also sense the timing of local depolarization events in the tissue in which impedance is sensed and derive therefrom the propagation velocities of the sensed depolarization events. The systems and methods match the derived tissue electrical characteristics with the derived propagation velocities in spatial relation to the electrodes to characterize the morphology of the contacted heart tissue to identify a potential ablation site.

    Abstract: Systems and methods sense electrical events about a selected annulus region (26, 30) of the heart (10) to identify the location of an accessory pathway. They establish a contact site between heart tissue and a multi-electrode array (E1-E10) conforming to the circumferential geometry of the selected annulus region (26, 30). The system and methods maintain this site, while conveying signals representing electrical events sensed by bipolar pairs of the electrodes (E1-E10). The systems and methods display the signals as graphic information that represents the time differences (T1, T2) between the atrium (A) and ventricular (V) electrogram complexes sensed by the pairs (E1-E10) on the selected annulus region (26, 30). The pairs (E1-E10) displaying the least time separation between the complexes (A, V) identifies the region of the accessory pathway. With this information, energy is conveyed to the electrodes of the selected pair to ablate tissue.

    Abstract: Systems and methods sense electrical events in heart tissue to identify the location of an arrhythmogenic focus for ablation. The systems and methods establish a contact site between heart tissue and a curvilinear electrode array (e1-e4 or E1-E4). The systems and methods monitor signals representing electrical events sensed by the electrodes in the contact site. The signals are displayed as graphic information that represents the time sequence in which the electrodes sense a given electrical event. By moving the electrode array (e1-e4 or E1-E4) to one or more additional contact sites in the general direction of the electrode that first sensed the electrical event, the physician homes in on a contact site in which all electrodes on the array sense the given electrical event at generally the same time. This contact site contains the arrhythmogenic focus. The systems and methods convey ablating energy to bipolar pairs of the electrodes to form large bipolar lesins in heart tissue.
