Abstract
Abstract An apparatus for defibrillating a mammal in need of defibrillation comprising: a) a sensing means for determining the mammal's fibrillation cycle length; b) a shocking means for administering bursts of electrical current to a mammal; and c) a timing means, connected electrically to said sensing means and said shocking means, for activating said shocking means such that said means delivers a plurality of bursts of electrical current sequentially to said mammal, the timing between said bursts being based upon the fibrillation cycle length determined by said sensing means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
An apparatus for defibrillating a mammal in need of defibrillation comprising: a) a sensing means for determining the mammal's fibrillation cycle length; b) a shocking means for administering bursts of electrical current to a mammal; and c) a timing means, connected electrically to said sensing means and said shocking means, for activating said shocking means such that said means delivers a plurality of bursts of electrical current sequentially to said mammal, the timing between said bursts being based upon the fibrillation cycle length determined by said sensing means.
Claim 2
Independent Claim
88 words
An apparatus for defibrillating a mammal in need of defibrillation comprising: a) a sensing means for determining the mammal's fibrillation cycle length; b) a shocking means for administering bursts of electrical current to a mammal; and c) a timing means, connected electrically to said sensing means and said shocking means, for activating said shocking means such that said means delivers a plurality of bursts of electrical current sequentially to said mammal, the timing between said bursts being based upon the fibrillation cycle length determined by said sensing means.
Claim 3
Dependent Claim
14 words
An apparatus of Claim 1 wherein the plurality of bursts consists of two bursts.
Claim 4
Dependent Claim
14 words
An apparatus of Claim 1 wherein the plurality of bursts consists of three bursts.
Claim 5
Independent Claim
35 words
An apparatus of any of Claims 1, 2 or 3 wherein the timing between each pair of bursts of electrical current is independently from about 30% to about 200% of the mammal's fibrillation cycle length.
Claim 6
Independent Claim
32 words
An apparatus of any of Claims 1, 2 or 3 wherein the timing between each pair of bursts is independently from about 60% to about 85% of the mammal's fibrillation cycle length.
Claim 7
Independent Claim
31 words
An apparatus of any of Claims 1, 2 or 3 wherein the timing between each pair of bursts is independently about 75% to about 85% of the mammal's fibrillation cycle length.
Claim 8
Independent Claim
23 words
An apparatus of any of Claims 1 to 6 wherein the bursts of electrical current are administered within the body of the mammal.
Claim 9
Independent Claim
