Abstract

A container for a tissue implantable solid filler material is disclosed. The filler material can be directly inserted into a cavity within the tissue or into a shell can be inserted into the cavity which either already contains the filler or has the filler added thereto during implantation. Methods for packaging the filler material are also disclosed.

Claims

1. An implant for tissue replacement or augmentation comprising a shell including an amount of a sterile continuous filler material, where the amount of filler material corresponds to a desired volume of the implant and where the material is a continuous yarn and the material is a polyolefin.

2. The implant of claim 1, wherein the continuous yarn is polypropylene yarn.

3. An implant for tissue replacement or augmentation comprising a shell including an amount of a sterile continuous filler material, where the amount of filler material corresponds to a desired volume of the implant and where the material is a continuous fiber, a continuous filament, a continuous mono-filament, a continuous yarn, a continuous fabric, or combinations or mixtures thereof and where the material is a synthetic material selected from the group consisting of a polyolefin, polyester, polyamide, polyimide, and combinations or mixtures thereof;

a natural material selected from the group consisting of silk, cotton, cellulose, and combinations or mixtures thereof; and

combinations or mixtures of the natural and synthetic materials.

4. The implant of claim 3, wherein the material includes a bioerodible outer coating and a non-bioerodible inside.

5. The implant of claim 4, wherein the inside comprises a synthetic material selected from the group consisting of a polyolefin, polyester, polyamide, polyimide, combination, and mixtures thereof;

a natural material selected from the group consisting of silk, cotton, cellulose, combinations and mixtures thereof; and

combinations or mixtures of the natural and synthetic materials and wherein the outer coating polylactides, polyglycolides, polycaprolactones, polyanhydrides, polyamides, polyurethanes, polyesteramides, polyorthoesters, polydioxanones, polyacetals, polyketals, polycarbonates, polyorthocarbonates, polyphosphazenes, polyhydroxybutyrates, polyhydroxyvalerates, polyalkylene oxalates, polyalkylene succinates, poly(malic acid), poly(amino acids), poly(methyl vinyl ether), poly(maleic anhydride), chitin, chitosan, and copolymers, terpolymers, or higher poly-monomer polymers thereof or combinations or mixtures thereof.

6. An implant for tissue replacement or augmentation comprising an amount of a sterile, continuous implant filler material, where the amount of filler material corresponds to a desired implant volume and is implanted directly into a cavity formed in a tissue site, where the material is a continuous fiber, a continuous filament, a continuous mono-filament, a continuous yarn, a continuous fabric, or combinations or mixtures thereof and where the material is a synthetic material selected from the group consisting of a polyolefin, polyester, polyamide, polyimide, and combinations or mixtures thereof;

a natural material selected from the group consisting of silk, cotton, cellulose, and combinations or mixtures thereof; and

combinations or mixtures of the natural and synthetic materials.

7. The implant of claim 6, wherein the material is a continuous yarn.

8. The implant of claim 7, wherein the continuous yarn is polypropylene yarn.

9. The implant of claim 6, wherein the material includes a bioerodible outer coating and a non-bioerodible inside.

10. The implant of claim 9, wherein the inside comprises a synthetic material selected from the group consisting of a polyolefin, polyurethane, polyester, polyamide, polyimide, hydrogel, ionomer, combination, and mixtures thereof;

a natural material selected from the group consisting of silk, cotton, cellulose, combinations and mixtures thereof; and

combinations or mixtures of the natural and synthetic materials and wherein the outer coating polylactides, polyglycolides, polycaprolactones, polyanhydrides, polyamides, polyurethanes, polyesteramides, polyorthoesters, polydioxanones, polyacetals, polyketals, polycarbonates, polyorthocarbonates, polyphosphazenes, polyhydroxybutyrates, polyhydroxyvalerates, polyalkylene oxalates, polyalkylene succinates, poly(malic acid), poly(amino acids), poly(methyl vinyl ether), poly(maleic anhydride), chitin, chitosan, and copolymers, terpolymers, or higher poly-monomer polymers thereof or combinations or mixtures thereof.

11. An implant for tissue replacement or augmentation comprising a shell including an amount of a sterile continuous filler material comprising a synthetic material selected from the group consisting of a polyolefin, polyurethane, polyester, polyamide, polyimide, hydrogel, ionomer, combination, and mixtures thereof;

a natural material selected from the group consisting of silk, cotton, cellulose, combinations and mixtures thereof; and

combinations or mixtures of the natural and synthetic materials, where the amount of filler material corresponds to a desired volume of the implant.

12. The implant of claim 11, wherein the material is a continuous fiber, a continuous filament, a continuous mono-filament, a continuous yarn, a continuous fabric, or combinations or mixtures thereof.

13. The implant of claim 11, wherein the material is a continuous yarn and the material is a polyolefin.

14. The implant of claim 13, wherein the continuous yarn is polypropylene yarn.
