    摘要： Cardiac tissue ablation catheters including an inflatable and flexible toroidal or spherically shaped balloon disposed at a distal region of an elongate member, a flexible circuit carried by an outer surface of the balloon, the flexible circuit including, a plurality of flexible branches conforming to the radially outer surface of the balloon, each of the plurality of flexible branches including a substrate, a conductive trace carried by the substrate, and an ablation electrode carried by the substrate, the ablation electrode in electrical communication with the conductive trace, and an elongate shaft comprising a guidewire lumen extending in the elongate member and extending from a proximal region of the inflatable balloon to distal region of the inflatable balloon and being disposed within the inflatable balloon, wherein a distal region of the elongate shaft is secured directly or indirectly to the distal region of the inflatable balloon.
