Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 52 words
A method for improving cardiac function, comprising: inserting a compressive device into an intrapericardial space about a lower end portion of a heart; and after the inserting of said compressive device into the intrapericardial space, operating said compressive device to compress and close off lower portions of both ventricles of the heart.
Claim 2
Independent Claim 52 words
A method for improving cardiac function, comprising: inserting a compressive device into an intrapericardial space about a lower end portion of a heart; and after the inserting of said compressive device into the intrapericardial space, operating said compressive device to compress and close off lower portions of both ventricles of the heart.
Claim 3
Dependent Claim 47 words
The method defined in claim 1 wherein said compressive device includes a plurality of prongs or tines each connected at one end to the other prongs or tines, the operating of said compressive device including pivoting each of said prongs or tines about the respective one end.
Claim 4
Dependent Claim 28 words
The method defined in claim 2 wherein at least one of said prongs or tines is provided with a tooth, further comprising inserting said tooth into the heart.
Claim 5
Dependent Claim 31 words
The method defined in claim 2 wherein the operating of said compressive device includes turning a camming mechanism to pivot each of said prongs or tines about the respective one end.
Claim 6
Dependent Claim 24 words
The method defined in claim 2 wherein the inserting of said compressive device includes inserting said compressive device through a trocar sleeve or cannula.
Claim 7
Dependent Claim 24 words
The method defined in claim 1 wherein the inserting of said compressive device includes inserting said compressive device through a trocar sleeve or cannula.
Claim 8
Independent Claim 84 words
A method for improving cardiac function, comprising: inserting a compressive device having a plurality of spaced members into an intrapericardial space about a portion of a heart, at least one of said spaced members being provided with a tooth; after the inserting of said compressive device into the intrapericardial space, operating said compressive device to compress and close off a portion of at least one ventricle of the heart; and inserting said tooth into the heart to anchor said compressive device to the heart.
Claim 9
Independent Claim 84 words
A method for improving cardiac function, comprising: inserting a compressive device having a plurality of spaced members into an intrapericardial space about a portion of a heart, at least one of said spaced members being provided with a tooth; after the inserting of said compressive device into the intrapericardial space, operating said compressive device to compress and close off a portion of at least one ventricle of the heart; and inserting said tooth into the heart to anchor said compressive device to the heart.
Claim 10
Dependent Claim 47 words
The method defined in claim 7 wherein said spaced members are a plurality of prongs or tines each connected at one end to the other prongs or tines, the operating of said compressive device including pivoting each of said prongs or tines about the respective one end.
Claim 11
Dependent Claim 31 words
The method defined in claim 8 wherein the operating of said compressive device includes turning a camming mechanism to pivot each of said prongs or tines about the respective one end.
Claim 12
Dependent Claim 33 words
The method defined in claim 7 wherein said spaced members are provided with a plurality of teeth, further comprising inserting said teeth into the heart to anchor said compressive device to the heart.
Claim 13
Dependent Claim 24 words
The method defined in claim 7 wherein the inserting of said compressive device includes inserting said compressive device through a trocar sleeve or cannula.
Claim 14
Independent Claim 117 words
A method for improving cardiac function, comprising: inserting a compressive device into an intrapericardial space about a lower end portion of a heart, said compressive device including a plurality of prongs or tines each connected at one end to the other prongs or tines; and after the inserting of said compressive device into the intrapericardial space, operating said compressive device to compress and close off lower portions of both ventricles of the heart, the operating of said compressive device including pivoting each of said prongs or tines about the respective one end, the operating of said compressive device further including turning a camming mechanism to pivot each of said prongs or tines about the respective one end.
Claim 15
Independent Claim 117 words
A method for improving cardiac function, comprising: inserting a compressive device into an intrapericardial space about a lower end portion of a heart, said compressive device including a plurality of prongs or tines each connected at one end to the other prongs or tines; and after the inserting of said compressive device into the intrapericardial space, operating said compressive device to compress and close off lower portions of both ventricles of the heart, the operating of said compressive device including pivoting each of said prongs or tines about the respective one end, the operating of said compressive device further including turning a camming mechanism to pivot each of said prongs or tines about the respective one end.
