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.

Abstract: An anchor configured to maximize the surface area of the anchor to improve anchor retention is disclosed. The anchor may be configured with a width that differs from a thickness of the anchor. In some embodiments, the anchor be configured as a helical ribbon defining a central lumen about a central axis extending through the helical ribbon. The helical ribbon may vary in width, thickness, central lumen diameter, or a combination thereof, along its extent. The anchor may include retention features that are configured to promote tissue and/or implant interaction for improved anchor retention.
