Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
80 words
A valve apparatus for deploying in, and securing to, a tissue annulus, said valve comprising: a uni-directional valve portion for passing fluid in one direction and obstructing fluid in an opposite direction; a connector band located circumferentially around, and attached to, said valve portion; and a plurality of barbed fingers located circumferentially around, and attached to, said band, said fingers being oriented substantially parallel to the direction of blood flow and adapted to secure said valve to said tissue annulus.
Claim 2
Dependent Claim
80 words
A valve apparatus for deploying in, and securing to, a tissue annulus, said valve comprising: a uni-directional valve portion for passing fluid in one direction and obstructing fluid in an opposite direction; a connector band located circumferentially around, and attached to, said valve portion; and a plurality of barbed fingers located circumferentially around, and attached to, said band, said fingers being oriented substantially parallel to the direction of blood flow and adapted to secure said valve to said tissue annulus.
Claim 3
Dependent Claim
42 words
The valve of claim 1 , wherein said fingers can be expanded from a first position adjacent to said band, engaged to said tissue annulus, and returned to said first position following said engagement, thereby securing said band to said tissue annulus.
Claim 4
Dependent Claim
15 words
The valve of claim 1 , wherein said fingers are formed from an elastic material.
Claim 5
Dependent Claim
31 words
The valve of claim 1 , wherein said band comprises a gasket located around an outer circumference of said band, said gasket for sealing between said band and said tissue annulus.
Claim 6
Dependent Claim
20 words
The valve of claim 1 , wherein said fingers are substantially parallel to a central longitudinal axis of said band.
Claim 7
Dependent Claim
79 words
A valve apparatus for deploying in, and securing to, a tissue annulus, said valve comprising: a uni-directional valve portion for passing fluid in one direction and obstructing fluid in an opposite direction, said valve having a fixed outer circumference; and a plurality of barbed fingers located circumferentially around, and attached to, the outer circumference of said valve, said fingers being oriented substantially parallel to the direction of blood flow and adapted to secure said valve to said tissue annulus.
Claim 8
Dependent Claim
79 words
A valve apparatus for deploying in, and securing to, a tissue annulus, said valve comprising: a uni-directional valve portion for passing fluid in one direction and obstructing fluid in an opposite direction, said valve having a fixed outer circumference; and a plurality of barbed fingers located circumferentially around, and attached to, the outer circumference of said valve, said fingers being oriented substantially parallel to the direction of blood flow and adapted to secure said valve to said tissue annulus.
Claim 9
Dependent Claim
24 words
The valve of claim 6 , wherein said fingers are adapted to secure said valve to said tissue annulus upon deployment of said valve.
Claim 10
Dependent Claim
42 words
The valve of claim 6 , wherein said fingers can be expanded from a first position adjacent to said valve, engaged to said tissue annulus, and returned to said first position following said engagement, thereby securing said valve to said tissue annulus.
Claim 11
Dependent Claim
15 words
The valve of claim 6 , wherein said fingers are formed from an elastic material.
Claim 12
Dependent Claim
31 words
The valve of claim 6 , wherein said valve comprises a gasket located around an outer circumference of said valve, said gasket for sealing between said valve and said tissue annulus.
Claim 13
Dependent Claim
20 words
The valve of claim 6 , wherein said fingers are substantially parallel to a central longitudinal axis of said valve.
