Abstract
Abstract An implantable cardioverter having circuitry for generating high energy cardioversion and defibrillation pulses. The output circuitry is so configured that it may provide simultaneous pulse, multiple electrode; sequential pulse, multiple electrode; or single pulse, two electrode defibrillation and/or cardioversion pulse regimens. The output circuitry is configured to allow delivery of energy sequentially from two capacitor banks during sequential pulse regimens and to deliver the energy stored in both capacitor banks simultaneously during simultaneous pulse, multiple electrode and single pulse, two electrode defibrillation pulse regimens.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
A cardioverter comprising: means for coupling said cardioverter to at least first, second and third electrodes; first and second capacitor means for storing electrical energy; control means for generating first and second control signals; and pulse generating means, responsive to said first and second control signals for delivering only the energy stored in said first capacitor means between one of said first and second electrodes and said third electrode in response to said first control signal, and means for delivering energy stored in said first and second capacitor means between the other of said first and second electrodes and said third electrode in response to said second control signal.
Claim 2
Dependent Claim
109 words
A cardioverter comprising: means for coupling said cardioverter to at least first, second and third electrodes; first and second capacitor means for storing electrical energy; control means for generating first and second control signals; and pulse generating means, responsive to said first and second control signals for delivering only the energy stored in said first capacitor means between one of said first and second electrodes and said third electrode in response to said first control signal, and means for delivering energy stored in said first and second capacitor means between the other of said first and second electrodes and said third electrode in response to said second control signal.
Claim 3
Dependent Claim
37 words
A cardioverter according to claim 1 further comprising means for generating a third control signal and means for internally discharging the energy stored on said first and second capacitor means in response to said third control signal.
Claim 4
Dependent Claim
24 words
A cardioverter according to claim 1 wherein said control means comprises means for providing said second control signal subsequent to said first control signal.
Claim 5
Dependent Claim
21 words
A cardioverter according to claim 1 wherein said control means comprises means for simultaneously generating said first and second control signals.
Claim 6
Dependent Claim
26 words
A cardioverter according to claim 1 wherein said control means comprises means for generating said second control signal in the absence of said first control signal.
Claim 7
Dependent Claim
61 words
A cardioverter according to claim 1 wherein said means for coupling said cardioverter to said first, second and third electrodes comprises a connector assembly including at least three receptacles and further includes at least three electrode leads, each coupled to a different one of said three receptacles, each provided with a cardioversion electrode for location in, on or around the heart.
