Abstract

An implantable structure, method for making the structure and method for using the structure, where the structure includes a combination of non-absorbable and absorbable components, and the implantable structure has a randomly uniform array of materials. The resulting implantable structure provides improved tissue ingrowth and flexibility after implantation and after absorption of the absorbable materials.

First claim

What is claimed is:

1. An implantable material comprising a substantially uniform woven fabric woven from a first yarn including at least a previously kinked first non-absorbable filament and a second yarn including at least a first absorbable filament having a lower melting point than said first non-absorbable filament, wherein the substantially uniform woven fabric is randomly buckled throughout so as to exist in a random three dimensional shape, and wherein said implantable material includes a plurality of random points in three dimensional space at which said first absorbable filaments have been melted and thereby thermally bonded to the un-melted first yarn to thereby maintain said implantable material in said random three dimensional shape.

2. The implantable material according to claim 1 , wherein said first or second yarn further comprises a second absorbable filament, and said first or second yarn further comprises a second non-absorbable filament.

3. The implantable material of claim 1 , wherein said first non-absorbable filament is polypropylene and said first absorbable filament is polydioxanone.

4. The implantable material of claim 2 , wherein said first absorbable filament is polyglactin, said second absorbable filament is polydioxanone, and said first non-absorbable filament is polypropylene.

5. The implantable material of claim 1 , wherein said implantable material has a thickness of about 0.01-0.125 inches.

6. The implantable material of claim 1 , wherein said first absorbable filament comprises polyglactin and said first non-absorbable filament comprises polypropylene.

7. The implantable material of claim 6 , wherein said first or second yarn further comprises a second absorbable filament, and wherein said second absorbable filament is polydioxanone.
