1. An implantable defibrillator comprising:

  • a housing having a length of about 30 cm and having first and second ends with a first electrode disposed on the first end and a second electrode disposed on the second end;

    the housing containing operational circuitry configured to receive cardiac signals from the first and second electrodes and deliver defibrillation energy via the first and second electrodes;

    the housing being shaped to allow implantation over the ribcage of a patient such that when the first end is disposed at a left parasternal location, the second end extends to underneath the patient'"'"'s left arm; and

    the housing being configured to define a first curvature across a first region near the first end and a second curvature across a second region near the second end, the first curvature being generally planar and the second curvature being generally non-planar, such that the housing will conform to the contours of the ribcage when implanted subcutaneously.
