摘要: Devices, systems and methods are disclosed for the ablation of tissue. A steerable ablation catheter can include one or more ablation elements at its distal end and one or more ablation elements fixedly attached to its shaft. The distal end of the ablation catheter can be deflected to assume a number of different deflection geometries in at least one direction along the shaft. One feature of the ablation catheter is that its shaft can comprise materials of differing durometers or stiffnesses attached together at a joint. Methods associated with use of the ablation catheter are also covered.

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. A shaft ablation electrode is mounted on the shaft proximal to the tip electrode. The catheter has a cooling fluid delivery system with a connection to a cooling fluid source. A fluid within the lumen of the elongate shaft penetrates the plug and delivers cooling fluid to the fluid exit port.

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.

摘要: Devices, systems and methods are disclosed for the mapping of electrical signals and the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be transformed from a compact, linear configuration to a helical configuration, such as to map and ablate pulmonary vein ostia.
