1. A non-woven porous mesh in sheet form, said mesh comprising:
- a continuous sheet having a substantially uniform thickness between opposite sides;
a series of openings extending through and from one to the other side of the sheet, said openings being distributed in a substantially uniform pattern throughout a two-dimensional area of the sheet; and
a series of raised protrusions extending substantially normal to and outwardly away from one side of said sheet, wherein the protrusions are of substantially uniform height and are distributed in a substantially uniform pattern corresponding to said pattern of openings but offset therefrom forming a topographical surface wherein said openings have an effective diameter of about 25 to 1000 μ
m, said openings have essentially the same effective diameter of said protrusions and are respectively centered within a rectangle defined by four adjacent protrusions within the body of said mesh.

Abstract
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 1000 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
