Abstract: A multi-pole synchronous pulmonary artery radiofrequency ablation catheter may comprise a control handle, a catheter body and an annular ring. One end of the catheter body may be flexible, and the flexible end of the catheter body may be connected to the annular ring. The other end of the catheter body may be connected to the control handle. A shape memory wire may be arranged in the annular ring. One end of the shape memory wire may extend to an end of the annular ring and the other end of the shape memory wire may pass through a root of the annular ring and be fixed on the flexible end of the catheter body. The annular ring may be provided with an electrode group. The device possesses advantages of simple operation, short operation time and controllable precise ablation. The device can be used to treat pulmonary hypertension with pulmonary denervation.

Abstract: Systems, devices, and method for performing pulmonary artery denervation are disclosed. An ablation device is positioned in a pulmonary artery trunk of a patient. Target tissue is ablated in the pulmonary artery trunk under conditions effective to affect a reduction in mean pulmonary artery pressure and systolic pulmonary artery pressure. The target tissue includes at least one of the distal portion of the main pulmonary artery, the proximal portion of the left pulmonary artery, or the proximal portion of the right pulmonary artery.

Abstract: Disclosed herein is a controller for controlling ablation of a target tissue of a patient with an ablation device comprising at least one electrode and at least one sensor. The controller typically comprises a storage medium and one or more computing devices operably coupled with the storage medium. The storage medium can comprise patient image data and the one or more computing devices are configured to direct power to the at least one electrode.

Abstract: A multi-pole synchronous pulmonary artery radiofrequency ablation catheter includes an adjustment apparatus arranged on a control handle; a lead wire, a temperature sensing wire and a pull wire arranged in a cavity of a catheter body; and an annular ring connected to a flexible end of the catheter body. One end of the pull wire is connected to the flexible end and the other end of the pull wire is connected to the adjustment apparatus. The tension of the pull wire is adjusted through the adjustment apparatus to achieve radian control of the flexible end. A shape memory wire is arranged in the annular ring. The annular ring is provided with an electrode group with each electrode connected to the lead wire and temperature sensing wire; the lead wire and temperature sensing wire go through the catheter body and are electrically connected to the control handle.
