Abstract

The present invention relates to a prosthesis ( 10 ) intended to be implanted at an implantation site, comprising i) at least one fabric called the base fabric ( 2 ) having at least one apertured surface ( 3 ), ii) and at least one patch ( 4 ) provided with at least one barb ( 5 ) projecting from one of its surfaces and grippingly fastening said patch to said apertured surface of said base fabric at a specific place on said surface, said patch comprising at least one radiopaque element. The invention also relates to a kit comprising a fabric and a patch.

First claim

The invention claimed is:

1. A prosthesis comprising:
i) at least one base fabric having at least one apertured surface which promotes penetration of cells into the base fabric and cell recolonization of the prosthesis after implantation,
ii) and a plurality of repositionable gripping fabrics separate from the at least one base fabric, each repositionable gripping fabric in the form of a disc having a first apertured surface, a second surface opposite the first surface, at least one radiopaque element, and at least one barb projecting from the second surface of the repositionable gripping fabric and designed to grippingly fasten the repositionable gripping fabric to a first specific place on the at least one apertured surface of the at least one base fabric and is easily removed therefrom so as to be repositioned and refastened on a second specific place on the at least one apertured surface of the at least one base fabric, wherein each gripping fabric has an area ranging from 0.5 to 6 cm 2 and the first apertured surface promotes penetration of cells and preserves the cell recolonization of the prosthesis when the second surface of the gripping fabric is grippingly fastened to the apertured surface of the base fabric.

2. The prosthesis according to claim 1 , wherein the at least one base fabric has two apertured surfaces and one or more repositionable gripping fabrics are grippingly fastened to each of the two apertured surfaces.

3. The prosthesis according to claim 1 , wherein the at least one base fabric is a knit.

4. The prosthesis according to claim 1 , wherein the at least one barb is formed from a yarn made of a radiopaque material and constitutes the at least one radiopaque element of each repositionable gripping fabric.

5. The prosthesis according to claim 1 , wherein the at least one radiopaque element includes one or more radiopaque monofilament yarns forming each gripping fabric.

6. The prosthesis according to claim 1 , wherein the at least one radiopaque element is in the form of a coating made of radiopaque material deposited on at least one surface of each repositionable gripping fabric.

7. The prosthesis according to claim 1 , wherein the at least one radiopaque element is in the form of a coating made of radiopaque material deposited on a surface of each of the repositionable gripping fabrics by plasma-enhanced chemical vapor deposition.

8. The prosthesis according to claim 1 , wherein the plurality of repositionable gripping fabrics includes four repositionable gripping fabrics, each repositionable gripping fabric grippingly fastened to a corner of the base fabric.

9. The prosthesis according to claim 1 , wherein the at least one base fabric is a three-dimensional knit.

10. A kit comprising:
at least one base fabric having at least one apertured surface which promotes penetration of cells into the base fabric and cell recolonization of the prosthesis, and,
a plurality of repositionable gripping fabrics separate from the at least one base fabric, each repositionable gripping fabric in the form of a disc having a first apertured surface, a second surface opposite the first surface, at least one radiopaque element and at least one barb projecting from the second surface of each repositionable gripping fabric, said at least one barb designed for grippingly fastening each repositionable gripping fabric to at a first specific place on the at least one apertured surface of the at least one base fabric and easily removed therefrom so as to be repositioned and refastened on a second specific place on the at least one apertured surface of the at least one base fabric, wherein each gripping fabric has an area ranging from 0.5 to 6 cm 2 and the first apertured surface promotes penetration of cells and preserves the cell recolonization of the prosthesis when the second surface of the gripping fabric is grippingly fastened to the apertured surface of the base fabric.

11. A prosthesis comprising:
i) at least one base fabric having at least one apertured surface which promotes penetration of cells into the base fabric and cell recolonization of the prosthesis after implantation, and
ii) a plurality of planar repositionable gripping fabrics separate from the at least one base fabric, each planar repositionable gripping fabric having a first apertured surface, a second surface opposite the first surface, at least one radiopaque element, and at least one barb projecting from the second surface of the repositionable gripping fabric and designed to grippingly fasten the second surface of the repositionable gripping fabric to a first specific place on the at least one apertured surface of the at least one base fabric and is easily removed therefrom so as to be repositioned and refastened on a second specific place on the at least one apertured surface of the at least one base fabric, wherein the first apertured surface of the gripping fabric promotes penetration of cells and preserves the cell recolonization of the prosthesis when the second surface of the gripping fabric is grippingly fastened to the apertured surface of the base fabric.
