A switching assembly for transferring trains of pulses, including a first terminal and a second terminal. A first plurality of first relays is connected in parallel, and have first contacts connected to the first assembly terminal, and second contacts. A first capacitor is connected in parallel with the first relays. A second plurality of second relays is connected in parallel, and have third contacts, and fourth contacts connected to the second assembly terminal. A second capacitor is connected in parallel with the second relays. A connection connects the second contacts to the third contacts. The pulses have amplitudes of at least 2 kilovolts. On activation of the first and second relays the first and second contacts connect and the third and fourth contacts connect, so that the first and second assembly terminals connect. On deactivation of the first and second relays the first and second assembly terminals disconnect.

High power multiplexer with low power components

An electroporation ablation system includes a probe to be inserted into a body part of a living subject, and including a distal end including at least one electrode, body-surface patches to be applied to a skin surface, an ablation power generator to apply at least one first electrical pulse train between the electrode(s) and first one(s) of the body-surface patches, and a processor to provide a measurement of movement of the living subject responsively to applying the first electrical pulse train(s) between the electrode(s) and the first one(s) of the body-surface patches, and select second one(s) of the body-surface patches responsively to the measurement of movement, and wherein the ablation power generator is configured to apply at least one second electrical pulse train between the electrode(s) and the second one(s) of the body-surface patches.

High frequency unipolar electroporation ablation

A pulsed field ablation (PFA) system includes a composite electrode, a body-surface electrode, a PFA generator, and a processor. The composite electrode is coupled to a distal end of a catheter configured for insertion into an organ of a patient. The body-surface electrode is configured to be attached to a skin of the patient. The PFA generator is configured to be electrically connected to the composite electrode of the catheter and to the body-surface electrode, and to generate Direct-Current (DC) PFA pulses. The processor is configured to control the PFA generator to apply the DC PFA pulses between the composite electrode and the body-surface electrode while the composite electrode is placed in contact with target tissue of the organ and the body-surface electrode is in contact with the skin of the patient.
