Abstract
An implantable biodegradable device is disclosed containing a fibrous matrix, the fibrous matrix being constructed from fibers A and fibers B, wherein fibers A biodegrade faster than fibers B, fibers A and fibers B are present in relative amounts and are organized such that the fibrous matrix is provided with properties useful in repair and/or regeneration of mammalian tissue.
Claims28
An implantable, biodegradable device, comprising a fibrous matrix, said fibrous matrix comprising first fibers A and second fibers B, wherein fibers A biodegrade faster than fibers B, fibers A and B are present in relative amounts and are organized such that the fibrous matrix is provided with properties useful in repair and/or regeneration of mammalian tissue, wherein one of fibers A and B comprises a biodegradable polymer and one of fibers A and B comprises a biodegradable glass, and wherein the fibrous matrix comprises a gradient structure comprising a transition in the relative concentration of fibers A to fibers B.
