The present disclosure provides electroporation systems and methods of preconditioning tissue for electroporation therapy. An electroporation generator includes an electroporation circuit, a preconditioning circuit, and a controller. The electroporation circuit is configured to be coupled to a catheter for delivering the electroporation therapy to target tissue of the patient. The electroporation circuit is further configured to transmit an electroporation signal through the catheter. The preconditioning circuit is configured to be coupled to a preconditioning electrode for stimulating skeletal muscle tissue of the patient. The preconditioning circuit is further configured to transmit a preconditioning signal to the preconditioning electrode. The controller is coupled to the electroporation circuit and the preconditioning circuit, and is configured to synchronize transmissions of the electroporation signal and the preconditioning signal such that the preconditioning signal is transmitted prior to transmission of the electroporation signal.

Electroporation system and method of preconditioning tissue for electroporation therapy

A system that interfaces with a workstation endocardial mapping system allows for the rapid and successful ablation of cardiac tissue. The system allows a physician to see a representation of the physical location of a catheter in a representation of an anatomic model of the patient's heart. The workstation is the primary interface with the physician. A servo catheter having pull wires and pull rings for guidance and a servo catheter control system are interfaced with the workstation. Servo catheter control software may run on the workstation. The servo catheter is coupled to an RF generator. The physician locates a site for ablation therapy and confirms the location of the catheter. Once the catheter is located at the desired ablation site, the physician activates the RF generator to deliver the therapy.

Radio frequency ablation servo catheter and method

A medical system for finding and displaying the location of electrodes within the body. The electrodes may be used to measure the voltage on the heart wall and display this as an activation map on a geometry representing the heart chamber.
