ABLATION POWER SUPPLY

Abstract: apparatus, consisting of a power supply having a first electrical connection to a relatively high voltage source and connectable to ablation circuitry in a catheter via a second electrical connection. there are rechargeable first and second subsidiary power sources in the power supply. the apparatus also has a control unit, and a first switch alternately connecting the ablation circuitry to the first and second subsidiary power sources responsively to control signals from the control unit. the apparatus also has a second switch alternately connecting one of the first and second subsidiary power sources to the high voltage source for recharging thereof responsively to the control signals while the one of the first and second subsidiary power sources is disconnected from the ablation circuitry and another of the first and second subsidiary power sources is connected to the ablation circuitry by the first switch.
