Conduction block verification probe and method of use
First Claim
1. A bipolar conduction block verification probe comprising:
- an elongate probe shaft having a proximal end and a distal end;
a first pacing electrode and a second pacing electrode exposed on a distal-facing surface at the distal end of the elongate probe shaft; and
a first wire connected to the first pacing electrode and extending through the elongate probe shaft to a first electrical connector configured for connection to an external bipolar pacing pulse generator and a second wire connected to the second pacing electrode and extending through the elongate probe shaft to a second electrical connector configured for connection to the external bipolar pacing pulse generator,wherein the elongate probe shaft includes a malleable member capable of being bent to a desired configuration and maintaining the desired configuration, wherein the elongate probe shaft is configured with a polymer tube having a first lumen and a second lumen, and wherein the malleable member is an elongated member that extends through the first lumen and the first wire and the second wire extend through the second lumen.

Abstract
Devices and methods provide for ablation of cardiac tissue for treating cardiac arrhythmias such as atrial fibrillation. Although the devices and methods are often to be used to ablate epicardial tissue in the vicinity of at least one pulmonary vein, various embodiments may be used to ablate other cardiac tissues in other locations on a heart. Devices generally include at least one tissue contacting member for contacting epicardial tissue and securing the ablation device to the epicardial tissue, and at least one ablation member for ablating the tissue. Various embodiments include features, such as suction apertures, which enable the device to attach to the epicardial surface with sufficient strength to allow the tissue to be stabilized via the device. For example, some embodiments may be used to stabilize a beating heart to enable a beating heart ablation procedure.
