Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
A suturing ring for connecting an artificial heart valve body with the heart tissues by sutures comprising a one-piece textile fabric having a cylindrical collar of single thickness for surrounding a portion of an artificial heart valve body and having a fashioned skirt portion of a single-thickness periphery radially outstanding from the cylindrical collar axis to a substantial extent from said collar and at an angle thereto with a selvage peripheral edge to prevent fraying, said skirt portion having a plurality of annularly disposed holes of a size larger than the porosity of the fabric mesh with said holes disposed inwardly from the peripheral selvage edge thereof.
Claim 2
Dependent Claim
107 words
A suturing ring for connecting an artificial heart valve body with the heart tissues by sutures comprising a one-piece textile fabric having a cylindrical collar of single thickness for surrounding a portion of an artificial heart valve body and having a fashioned skirt portion of a single-thickness periphery radially outstanding from the cylindrical collar axis to a substantial extent from said collar and at an angle thereto with a selvage peripheral edge to prevent fraying, said skirt portion having a plurality of annularly disposed holes of a size larger than the porosity of the fabric mesh with said holes disposed inwardly from the peripheral selvage edge thereof.
Claim 3
Dependent Claim
12 words
A suturing ring as in claim 1 wherein said ring is seamless.
Claim 4
Dependent Claim
19 words
A suturing ring as in claim 1 wherein said ring is seamless and formed of textile fibers knitted together.
