First Claim
Patent Images
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.

13. 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 portion of the lead assembly disposed within the channel has a first length, and a second position in which the portion of the lead assembly disposed within the channel has a second length less than the first length, and the securing structure selectively non-slidably secures the lead assembly to the housing in the first and second positions.

14. An implantable cardioverter-defibrillator comprising:
-
a housing defining a slot and having a first electrode disposed thereon;
an elongated lead assembly including a second electrode, wherein at least a portion of the lead assembly is slidably disposed within the slot for selective telescoping movement relative to the housing such that the lead assembly is selectively adjustable between a first extended position and a second contracted position;a securing structure for selectively non-slidably securing the lead assembly to the housing in at least first and second positions; and an electrical circuit located within and electrically coupled to the housing; wherein the housing includes an electrical contact within the slot and electrically coupled to the electrical circuit, and the lead assembly includes an electrical contact disposed thereon and electrically coupled to the second electrode; wherein when the lead assembly is slidably adjusted to the first position, the electrical contact on the lead assembly engages the electrical contact on the housing, thereby electrically coupling the lead assembly to the housing; wherein the housing includes a second electrical contact within the slot and electrically coupled to the electrical circuit; and wherein when the lead assembly is slidably adjusted to the second position, the electrical contact on the lead assembly engages the second electrical contact on the housing, thereby electrically coupling the lead assembly to the housing. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
