Publication number: 20220401146Abstract: Provided herein are systems for treating tissue of a patient. The system comprises an energy delivery console and at least one energy delivery device. The energy delivery console can provide a first dose of energy and a second dose of energy. An energy delivery device comprises a first delivery element configured to deliver the first dose of energy to target tissue, and a second delivery element configured to deliver the second dose of energy to the target tissue. The first dose of energy can comprise a delivery of energy that reversibly alters the target tissue, and the second dose of energy can comprise a delivery of energy that irreversibly alters the target tissue. The first dose of energy can be delivered to enhance a therapy provided by the second dose of energy.Type: ApplicationFiled: November 20, 2020Publication date: December 22, 2022Inventors: Alexander J.

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.
