Abstract: The present disclosure generally relates to devices, systems, and methods for ablating and occluding a body lumen or cavity, including those implementations for occluding the left atrial appendage of the heart. An example assembly includes a connector assembly having a connector assembly proximal end and a connector assembly distal end, the connector assembly proximal and distal ends being opposite ends of the connector assembly; and an expandable frame that is detachably disposed at the connector assembly distal end, the expandable frame having a plurality of deployment positions that includes a first deployed position in which the expandable frame is in a focal arrangement and a second deployed position in which the expandable frame is in a wide area arrangement; and where the connector assembly is operatively connected to the expandable frame and configured to facilitate moving the expandable frame between the plurality of deployment positions.

Abstract: A medical device includes an elongate hollow shaft having a shaft proximal end, a shaft distal end, and a lumen extending along the elongate hollow shaft. A handle is disposed at the shaft proximal end. A connector assembly having a connector assembly proximal end and a connector assembly distal end, the connector assembly proximal and distal ends being opposite ends of the connector assembly. An expandable frame is detachably disposed at the connector assembly distal end, the expandable frame including a plurality of interconnected members formed of an electrically conductive material, wherein the interconnected members in a first portion of the expandable frame are coated with a dielectric layer, and wherein the interconnected members in a second portion of the expandable frame are uncoated and configured as an electrode region of the expandable frame.
