    摘要： A catheter is disclosed comprising a catheter shaft including a proximal end and a distal end. A flexible framework can be connected to the distal end of the catheter shaft, wherein the flexible framework includes a plurality of heating electrodes and a temperature sensor. The plurality of heating electrodes can be configured to be heated to a first temperature, the first temperature being lower than which radio frequency ablation is performed. The plurality of heating electrodes can be configured to be heated to a second temperature, the second temperature being a temperature at which radio frequency ablation is performed.

    摘要： A catheter configured to deliver therapeutic energy to a tissue is disclosed. The catheter comprises an elongate shaft extending along a shaft longitudinal axis. The catheter further comprises a flexible tip assembly coupled to a distal end of the elongate shaft, the flexible tip assembly comprising at least three mapping electrodes equally spaced about a circumference of the flexible tip, a flexible ablation electrode, and a plurality of irrigation ports. The catheter further comprises an irrigation lumen extending through the elongate shaft and into an interior of the flexible tip assembly, wherein the irrigation lumen is configured to direct irrigation fluid to the plurality of irrigation ports.
