Devices and methods for mapping tissue, such as cardiac tissue, and applying electrical energy to ablate the tissue may include an applicator region comprising two or more wire electrodes that extend between the arms of the device as well as a plurality of mapping and/or sensing electrodes (e.g., ring electrodes) on the arms and/or the elongate body. These devices may sense electrical activity using the mapping electrodes and may deliver energy between the first wire electrode and the second wire electrode to ablate, for example, cardiac tissue.

Mapping and ablation applicators

Methods and apparatuses are disclosed for providing pulsed electrical treatment (including high voltage, sub-microsecond pulsed electric energy) to body vessels. The apparatus may include deployable electrodes that conform to transitional surfaces. These apparatuses may include multiple wire loops forming petal-like electrodes configured to expand with an expandable member, such as a balloon.

Circumferential ablation devices and methods

A novel catheter is disclosed comprising an electrode array that is capable of switching between a sensing configuration for sensing electrical signals of biological tissue and an ablation configuration for delivery of ablation energy at a region of interest. Irrigation ports are interlaced within the electrode array to vent irrigant during an ablation procedure to; prevent excessive heating, charring of tissue, coagulation of blood, and allow for efficient delivery of ablation therapy for maximum therapy efficacy. The novel catheter includes a plurality of splines with linear portions wherein the electrodes of the electrode array are disposed. The splines are connected by connectors which include one or more bends capable of storing potential energy when the bends are elastically deformed, enabling collapse and expansion of the catheter in a sheath. Software logic associated with this catheter analyzes sensing signals to diagnose critical regions of the biological rhythm disorder, and enables directional guidance to move the catheter to critical regions for therapy.
