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.
