1. An implantable cardioverter-defibrillator comprising:

  • a housing defining a channel, the housing having a first electrode disposed thereon;

    a lead assembly including a second electrode, wherein at least a portion of the lead assembly is slidably disposed within the channel for selective telescoping movement relative to the housing such that the lead assembly is selectively adjustable between a plurality of positions relative to the housing;

    a securing structure for selectively securing the lead assembly to the housing at a plurality of desired positions; and

    an electrical circuit located within the housing and electrically coupled to the housing;

    wherein the lead assembly is selectively slidably adjustable between a first position in which the first and second electrodes are spaced apart by a first distance, and a second position in which the first and second electrodes are spaced apart by a second distance greater than the first distance, and the securing structure selectively non-slidably secures the lead assembly to the housing in the first and second positions.
