Abstract
An example medical device is disclosed. The medical device includes a catheter shaft including a distal end portion, wherein the distal end portion includes an ablation assembly. The ablation assembly includes an expandable frame including a base, an end region and a plurality of struts extending between the base and the end region, the struts defining a plurality of apertures along the frame. The ablation assembly also includes an electrical circuit coupled to an inner surface of the second end region of the frame, the electrical circuit including a plurality of ablation electrodes coupled thereto. Further, the expandable frame is designed to shift from a delivery configuration in which the ablation electrodes face inward from the inner surface of the expandable frame to an expanded configuration in which the ablation electrodes face away from the base of the expandable frame.
