摘要：
A medical system includes an expandable structure and a first flexible circuit. The expandable structure is sized to be received in a chamber of a heart and is selectively moveable between a delivery configuration and an expanded configuration. The first flexible circuit includes an electrically insulative substrate including one or more layers. The first flexible circuit further includes a plurality of electrically conductive traces patterned on at least a portion of a first side of the electrically insulative substrate. At least a portion of a second side of the electrically insulative substrate is backed by at least a portion of a first side of a metallic backing that is provided by the expandable structure. At least a portion of the metallic backing is exposed to blood flow when the expandable structure is positioned in the chamber in the expanded configuration.
