Optional use of a lead for a unitary subcutaneous implantable cardioverter-defibrillator
First Claim
1. An implantable cardioverter-defibrillator comprising:
- a housing having first and second ends;
a first electrode disposed on the housing toward the first end;
a second electrode disposed on the housing toward the second end;
a lead having a third electrode thereon, the lead being coupled to the housing;
operational circuitry in the housing, the operational circuitry having output circuitry for providing a defibrillation output, the output circuitry coupled to each of the first, second and third electrodes such that the operational circuitry can deliver therapy using a plurality of electrode pairs including at least the combinations of the first and second or first and third electrodes.
