Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
112 words
A cardiac assist system for assisting a natural heart having ventricles which contract at a ventricular rate, said cardiac assist system adapted for coupling to a surgically prepared muscle responsively coupled to said heart and to a circulatory system, and said cardiac assist system comprising: a. control means adapted to be coupled to the heart and to the muscle for stimulating the muscle and for causing it to contract in synchrony with said ventricles of said heart; and b. means, coupled to said control means and adapted to be responsively coupled to the muscle, for monitoring a parameter indicative of a predetermined level corresponding to adequacy of circulatory support to the muscle.
Claim 2
Dependent Claim
112 words
A cardiac assist system for assisting a natural heart having ventricles which contract at a ventricular rate, said cardiac assist system adapted for coupling to a surgically prepared muscle responsively coupled to said heart and to a circulatory system, and said cardiac assist system comprising: a. control means adapted to be coupled to the heart and to the muscle for stimulating the muscle and for causing it to contract in synchrony with said ventricles of said heart; and b. means, coupled to said control means and adapted to be responsively coupled to the muscle, for monitoring a parameter indicative of a predetermined level corresponding to adequacy of circulatory support to the muscle.
Claim 3
Dependent Claim
38 words
The cardiac assist system according to claim 1 wherein said monitoring means comprises: a. means for sensing blood perfusion of the muscle; and b. means, responsively coupled to said sensing means, for storing data from said sensing means.
Claim 4
Dependent Claim
21 words
The cardiac assist system according to claims 2 further including means for telemetering out the data stored by said storing means.
Claim 5
Dependent Claim
15 words
A cardiac assist system according to claim 2 wherein said sensing means is an oximeter.
Claim 6
Dependent Claim
17 words
A cardiac assist system according to claim 4 wherein said oximeter is a two wavelength reflectance oximeter.
Claim 7
Dependent Claim
21 words
The cardiac assist system according to claim 4 further including means for telemetering out the data stored by said storing means.
Claim 8
Dependent Claim
22 words
The cardiac assist system according claim 1, wherein said monitoring means includes means for sensing a level of oxygen in the muscle.
Claim 9
Dependent Claim
100 words
An assist system for assisting an organ, said assist system adapted for coupling to a surgically prepared muscle responsively coupled to said organ and to a circulatory system- has been inserted after "muscle". the assist system comprising: a. control means adapted to be coupled to the organ and to the muscle for stimulating the muscle and for causing it to contract in a predetermined sequence; and b. means, coupled to said control means and adapted to be responsively coupled to the muscle, for monitoring a parameter indicative of a predetermined level corresponding to adequacy of circulatory support to the muscle.
Claim 10
Dependent Claim
100 words
An assist system for assisting an organ, said assist system adapted for coupling to a surgically prepared muscle responsively coupled to said organ and to a circulatory system- has been inserted after "muscle". the assist system comprising: a. control means adapted to be coupled to the organ and to the muscle for stimulating the muscle and for causing it to contract in a predetermined sequence; and b. means, coupled to said control means and adapted to be responsively coupled to the muscle, for monitoring a parameter indicative of a predetermined level corresponding to adequacy of circulatory support to the muscle.
