Patent ID: 7406350

Claim:
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.
