Abstract
Abstract A method for repairing tears in fibrocartilage and soft tissue. The clip has a pair of opposed legs formed of rigid biodegradable material. Each leg has at least one barb for easily penetrating the cartilage and soft tissue, and for opposing withdrawal from it. The legs are interconnected by a flexible section that is also biodegradable. The instrument for applying these clips has a pair of opposed jaws, each with at least one notch for holding the barbs of the clip. The jaws are biased apart in a normally open position and are interconnected to an actuating handle. The instrument further includes a device which closes the jaws when the handles are moved a first way relative to one another and opens them when the handles are moved the other way.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
47 words
A method for repairing a tear in the meniscus comprising: providing a staple having a pair of legs joined together by a flexible suture material; inserting the staple into the meniscus so the suture material overlies the tear; and bending the staple legs inwardly towards each other.
Claim 2
Independent Claim
47 words
A method for repairing a tear in the meniscus comprising: providing a staple having a pair of legs joined together by a flexible suture material; inserting the staple into the meniscus so the suture material overlies the tear; and bending the staple legs inwardly towards each other.
Claim 3
Dependent Claim
16 words
A method as in claim 1, wherein said staple legs and said suture material are biodegradable.
Claim 4
Independent Claim
38 words
A method of repairing a tear in the meniscus comprising: providing a staple having a pair of legs joined together by a flexible material; and inserting the staple into the meniscus so the flexible material overlies the tear.
Claim 5
Independent Claim
38 words
A method of repairing a tear in the meniscus comprising: providing a staple having a pair of legs joined together by a flexible material; and inserting the staple into the meniscus so the flexible material overlies the tear.
Claim 6
Dependent Claim
15 words
The method of claim 3, wherein the staple legs are composed of a biodegradable material.
Claim 7
Dependent Claim
14 words
The method of claim 4, wherein the flexible material is a biodegradable suture material.
Claim 8
Dependent Claim
14 words
The method of claim 3, wherein said legs are composed of a rigid material.
Claim 9
Dependent Claim
16 words
The method of claim 6 wherein each said leg includes at least one tissue retaining barb.
Claim 10
Independent Claim
86 words
The method of repairing a tear in the meniscus comprising: providing an instrument having a pair of opposed jaws; placing a staple having a pair of legs joined by a suture material in said jaws so each staple leg is received in the notch formed in each jaw; inserting the instrument in the body to position the jaws over the tear; squeezing said handles of the instrument to close the jaws; and releasing the staple from the jaws so that the flexible material overlies the tear.
Claim 11
Independent Claim
86 words
The method of repairing a tear in the meniscus comprising: providing an instrument having a pair of opposed jaws; placing a staple having a pair of legs joined by a suture material in said jaws so each staple leg is received in the notch formed in each jaw; inserting the instrument in the body to position the jaws over the tear; squeezing said handles of the instrument to close the jaws; and releasing the staple from the jaws so that the flexible material overlies the tear.
Claim 12
Dependent Claim
13 words
The method of claim 8, wherein the staple is composed of biodegradable material.
Claim 13
Dependent Claim
26 words
The method of claim 9, wherein each staple leg has an integral tissue retaining barb and said barb is positioned in the notch of the jaw.
Claim 14
Dependent Claim
28 words
The method of claim 10, wherein the step of releasing the staple comprises pulling a wire to actuate barb holding members to disengage the instrument from the barbs.
