Zusammenfassung:	A porous mesh for use in forming articles comprising a network of pores and protrusions. The porous mesh has a specifically delineated mesh structure having a pore/protrusion size between 25 and 1500 microns and the pore structure is based on a uniform distribution of pores and protrusions on a cast or molded sheet wherein said pores and protrusions have similar effective diameters. The resulting material is advantageously applied to several bio-medical applications, including reconstructive surgery and arterial replacement.
