Patent number: 9757194Abstract: 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.Type: GrantFiled: May 24, 2016Date of Patent: September 12, 2017Assignee: Medtronic Ablation Frontiers LLCInventors: Randell L. Werneth, Ricardo D. Roman, Christopher G. Kunis, Alexander J. Asconeguy, Sadaf Soleymani, Jeffrey Trinidad, Martin Chambers, Hakan Oral, Fred Morady, Jerald L. Cox, Guillermo W. Moratorio, Samuel Fu, J. Christopher Flaherty
