Ablation equipment for delivering non-thermal energy to treat target regions of tissue in organs and control method thereof

Ablation equipment for delivering non-thermal energy to treat target regions of tissue in organs of a subject, the ablation equipment comprising:

• an ablation catheter comprising:
• a catheter elongated shaft comprising an elongated shaft distal portion, wherein the catheter elongated shaft comprises a flexible body to navigate through body vessels;
• a shaft ablation assembly disposed at the elongated shaft distal portion and a distal ablation assembly extending out from the elongated shaft distal portion, wherein the shaft ablation assembly comprises a first plurality of electrodes fixedly disposed at the elongated shaft distal portion and a second plurality of electrodes fixedly disposed along the distal ablation assembly;
• and
• a power source electrically connected to the first plurality of electrodes and the second plurality of electrodes, wherein the power source is configured to generate electric voltage signals to energize each of the first plurality of electrodes and the second plurality of electrodes for delivering non-thermal energy to the tissue to be treated;
• wherein each of the electric voltage signals is a sinusoidal wave, and wherein the power source is configured to supply at least a first electrode and an adjacent second electrode of the first plurality of electrodes with sinusoidal electric voltage signals that are in phase with each other or out of phase with each other to generate a unipolar electric field and/or a bipolar electric field for delivering the non-thermal energy to the tissue to be treated;
• wherein the power source comprises a control unit and a power unit for generating the sinusoidal electric voltage signals, wherein the power unit is electrically connected to each of the first plurality of electrodes and the second plurality of electrodes;
• and
• wherein the power unit comprises one or more power modules equal to each other, and each power module is controlled by the control unit for generating the sinusoidal electric voltage signals starting from a constant supply voltage signal provided by the control unit.
