Abstract: 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.

Abstract: A method of treating tissue includes clamping tissue between an ultrasonic blade and a jaw member and simultaneously: transmitting ultrasonic energy to the ultrasonic blade to vibrate the ultrasonic blade at a first blade velocity thereby heating the clamped tissue; and supplying electrosurgical energy, at a constant voltage, to the jaw member and the ultrasonic blade at different potentials such that the electrosurgical energy is conducted therebetween and through the clamped tissue to heat the clamped tissue. An impedance of the clamped tissue is monitored and the simultaneous transmission of ultrasonic energy and supply of electrosurgical energy is terminated and/or a notification is output once the clamped tissue is sealed, as indicated by the impedance of the clamped tissue being equal to or greater than a threshold impedance. Surgical instruments and end effectors thereof for treating tissue in this manner are also provided.
