Abstract
Biomaterials are disclosed comprised of biodegradable, biocompatible, and bioabsorbable non-woven fabric materials for use in surgery for the guided regeneration of tissues. The non-woven fabric materials constitute threads embedded in a matrix, wherein both the matrix and the threads constitute auto-crosslinked hyaluronic acid.
Claims20
A non-woven fabric material, consisting essentially of auto-crosslinked hyaluronic acid.
A process for preparing a non-woven fabric material, which comprises producing a non-woven mesh of auto-crosslinked hyaluronic acid, spraying said mesh with a solution of auto-crosslinked hyaluronic acid, and chemically coagulating the sprayed mesh to fix the fibers of said mesh to one another to prepare a non-woven fabric material product.
A non-woven fabric material, consisting essentially of auto-crosslinked hyaluronic acid, wherein said auto-crosslinked hyaluronic acid contains carboxyl groups which are esterified with hydroxyl groups of the same molecule or different molecules.
