Abstract

A porous article comprising a three-dimensional network of interconnecting pores and a void volume between twenty and eighty percent. The porous article is manufactured using a specifically delineated mesh structure wherein the pore size, void volume and material properties are tightly controlled and easily varied. The resulting material is advantageously applied to several bio-medical applications, including reconstructive surgery and arterial replacement.
