    摘要: An ablation catheter for performing tissue ablation has an elongate shaft with a lumen. A tip ablation electrode is mounted on the distal end of the shaft. The tip electrode has walls that, together with the plug, define a chamber. The tip electrode has a fluid exit port. The catheter has a cooling fluid delivery system with a connection to a fluid source and a fluid delivery tube within the lumen of the elongate shaft. The fluid delivery tube penetrating said plug and delivers fluid to the fluid exit port. The catheter has a valve assembly in located in the chamber between the fluid delivery tube and the fluid exit port. The valve assembly prevents the flow of cooling fluid through the fluid delivery tube when in the closed position.

    摘要: An ablation catheter for performing tissue ablation, having an elongate shaft with a lumen and a tip ablation electrode at the distal end of the shaft. The tip electrode has a fluid exit port opening through the surface of the tip electrode and at least one channel extending along the surface of the tip electrode to allow fluid passage in the event that the fluid exit port is blocked. The catheter has a connector to a cooling fluid source, and a fluid delivery tube within the shaft lumen to deliver cooling fluid from the connector to the fluid exit port.
