Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
202 words
A ventricular assist device which can be implanted in a patient user exterior to the heart (102''), which comprises: - a pumping means (20) which includes one or more movable ventricle compression assemblies (118'') for engaging an outer surface of at least one heart ventricle (12''); - operating means for cyclically actuating the one or more compression assemblies, such that the ventricle is, first, compressed to aid blood ejection therefrom, and second, released to permit refilling; - control means (28) for regulating actuation of the operating means; and - an electrical power source (32); characterized in that the device also includes a means (40) for recording data produced during the operation of said ventricular assist device, the recording means being implantable and capable of transcutaneous interrogation; and that the pumping means (20) also includes: - a rigid support member (304) external to the heart; - at least one resilient band (300) having an intermediate portion surgically implantable in an interventricular wall (302) of the heart, the band having opposite ends which connect to the rigid support member (304); and - one or more of the movable ventricle compression assemblies (118'') positioned between the rigid support member (304) and the resilient band (300).

Dependent Claim

A ventricular assist device which can be implanted in a patient user exterior to the heart (102''), which comprises: - a pumping means (20) which includes one or more movable ventricle compression assemblies (118'') for engaging an outer surface of at least one heart ventricle (12''); - operating means for cyclically actuating the one or more compression assemblies, such that the ventricle is, first, compressed to aid blood ejection therefrom, and second, released to permit refilling; - control means (28) for regulating actuation of the operating means; and - an electrical power source (32); characterized in that the device also includes a means (40) for recording data produced during the operation of said ventricular assist device, the recording means being implantable and capable of transcutaneous interrogation; and that the pumping means (20) also includes: at least one resilient band (300') having an intermediate portion surgically implantable in an interventricular wall (302') of the heart and having end portions fixed to two movable ventricle compression assemblies (120''') such that actuation of the compression assemblies constricts the at least one resilient interventricular band and thereby compresses the ventricle.
