Abstract
Compositions-of-matter comprising a matrix made of one or more, preferably two or more elastic layers and one or more viscoelastic layer are disclosed. The compositions-of-matter are characterized by high water-impermeability and optionally by self-recovery. Processes of preparing the compositions-of-matter and uses thereof as tissue substitutes or for repairing damaged tissues are also disclosed.
Claims18
A composition-of-matter comprising a multi-layer matrix, said matrix comprising at least one layer of a viscoelastic polymeric material interposed between two or more layers of an elastic polymeric material, wherein:
- each of said two or more layers of said elastic polymeric material is in a form of a porous layer of polymeric fibers;
- said viscoelastic polymeric material is characterized by at least one of:
- (i) a glass transition temperature below 0° C., and (ii) a melting point at a temperature below 45° C.;
- said polymeric fibers comprise poly(lactic acid-co-ε-caprolactone);
- and
- said viscoelastic polymeric material comprises poly(lactic acid-co-ε-caprolactone).
