Abstract
Abstract A prosthetic tissue repair device having one or more eyelets, intended for use in the augmentation or replacement of biological tissue, and to a method of making such a device, and to a method of using such a device. The device is intended to function in parallel with or in place of biological tissue so that it is partially or entirely responsible for the forces normally transmitted through the tissue and can be intended to function in this capacity either temporarily, i.e., during healing of the biological tissue, or permanently, i.e., to replace the biological tissue.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
61 words
A tissue repair device comprised of a length of braided, biocompatible material having a hollow core for the entire length, said length having a first end portion, a second end portion disposed within the hollow core of the first end portion rendering the first and second end portions coaxial with each other, and a middle portion looped to form an eyelet.
Claim 2
Dependent Claim
61 words
A tissue repair device comprised of a length of braided, biocompatible material having a hollow core for the entire length, said length having a first end portion, a second end portion disposed within the hollow core of the first end portion rendering the first and second end portions coaxial with each other, and a middle portion looped to form an eyelet.
Claim 3
Dependent Claim
17 words

Claim 10
Independent Claim
121 words
A method of forming an eyelet at one end of a length of multiply-stranded braided biocompatible material for use as a tissue repair device, wherein said length has a first and second end and a hollow core connecting said ends, comprising the steps of: (a) separating the strands of said braided material to form an opening into the hollow core of said braided material; (b) inserting the first end of said braided material through the formed opening and into the hollow core of said braided material; (c) feeding the first end of said braided material through the formed opening and the hollow core toward the second end of said braided material until the eyelet so formed is of the desired size.
Claim 11
Independent Claim
121 words
A method of forming an eyelet at one end of a length of multiply-stranded braided biocompatible material for use as a tissue repair device, wherein said length has a first and second end and a hollow core connecting said ends, comprising the steps of: (a) separating the strands of said braided material to form an opening into the hollow core of said braided material; (b) inserting the first end of said braided material through the formed opening and into the hollow core of said braided material; (c) feeding the first end of said braided material through the formed opening and the hollow core toward the second end of said braided material until the eyelet so formed is of the desired size.
Claim 12
Dependent Claim
19 words
