1. An apparatus, comprising:
(a) a first electrical connection configured to couple with a high voltage source;
(b) a second electrical connection configured to couple with ablation circuitry in a catheter;
(c) a first rechargeable subsidiary power source;
(d) a second rechargeable subsidiary power source; and
(e) a switching assembly configured to transition between a first state and a second state;
the switching assembly in the first state being configured to:
(i) couple the first rechargeable subsidiary power source with the second electrical connection to thereby provide power from the first rechargeable subsidiary power source to the ablation circuitry, and
(ii) couple the second rechargeable subsidiary power source with the first electrical connection to thereby charge the second rechargeable subsidiary power source while the first rechargeable subsidiary power source provides power to the ablation circuitry;
the switching assembly in the second state being configured to:
(i) couple the second rechargeable subsidiary power source with the second electrical connection to thereby provide power from the second rechargeable subsidiary power source to the ablation circuitry, and
(ii) couple the first rechargeable subsidiary power source with the first electrical connection to thereby charge the first rechargeable subsidiary power source while the second rechargeable subsidiary power source provides power to the ablation circuitry.
