ABLATION EQUIPMENT FOR DELIVERING NON-THERMAL ENERGY TO TREAT TARGET REGIONS OF TISSUE IN ORGANS AND CONTROL METHOD THEREOF

摘要

The present invention relates to an ablation equipment (1000) for delivering non-thermal energy, particularly Irreversible Electroporation (IRE) energy, to treat target regions of tissue (41) in organs (44). The ablation equipment (1000) comprises an ablation catheter (1) and a single power source (4). The ablation catheter (1) comprises: a catheter elongated shaft (13) comprising at least an elongated shaft distal portion (17); said catheter elongated shaft (13) comprising a flexible body (27) to navigate through body vessels (208). The ablation catheter (1) further comprises a shaft ablation assembly (20) disposed at said elongated shaft distal portion (17). The shaft ablation assembly (20) comprises at least a plurality of electrodes (3, 30, 31) fixedly disposed at said elongated shaft distal portion (17). All electrodes of said at least a plurality (3, 30, 31) are electrically connected to the single power source (4). The single power source (4) is configured to generate electric voltage signals (Sa, Sb, Va, Vb) to energize each electrode for delivering the non-thermal energy to the tissue (41) to be treated. Each of said electric voltage signals (Sa, Sb, Va, Vb) is a sinusoidal wave, and the single power source (4) is configured to supply at least a first (30) and a second (31) electrodes (30, 31) that are adjacent to each other on said ablation catheter (1), with sinusoidal electric voltage signals 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 (41) to be treated.
