Abstract
An apparatus includes a catheter and an end effector. At least a portion of the catheter is sized and configured to fit within a lumen of a human cardiovascular system. The end effector is positioned at a distal end of the catheter. The end effector includes an expandable assembly and at least one flex circuit. The expandable assembly is configured to transition between a non-expanded state and an expanded state. The expandable assembly includes at least one deformable strut or cage. Each flex circuit includes a flexible substrate secured, without an adhesive, to the expandable assembly and an electrode secured to the flexible substrate. The expandable assembly in the expanded state is configured to urge the electrode into contact with tissue. The electrode has a fishbone-like configuration that defines a longitudinally elongated portion and a plurality of fingers extending transversely from the longitudinally elongated portion.
