Meshes of variable construction
First Claim
1. A substantially two-dimensional surgical mesh comprising a base material, said mesh comprising a central body comprising a first area of one side of the mesh that is provided with a first material and a plurality of arms emanating from the central body portion, wherein each of the arms has a width that is less than a width of the central body portion, wherein each of the arms comprises a second area that of said side is provided with a second material independently of said central body portion, wherein the first and second materials are different from one another, and wherein the first and second materials are selected from (a) materials that promote a tissue response, (b) materials having bioinert properties, (c) materials that block or delay tissue ingrowth, (d) materials that reduce tissue adhesions, (e) materials that reduce tissue erosion, (f) materials that promote bonding of the mesh to adjacent tissue, (g) biodegradable materials, and (h) materials that generate distinctive color from other portion of the mesh.

21. A substantially two-dimensional surgical mesh comprising a base material, said mesh comprising a central body comprising a first area of one side of the mesh that is provided with a first material and three or more arms emanating from the central body portion, wherein each of said arms has a width that is less than a width of the central body portion, wherein each of said arms comprises a second area of said side that is provided with a second material, independently of said central portion, wherein the first and second materials are different from one another, and wherein (i) said first area of the central body portion is bordered by an area that does not comprise said first material and/or (ii) wherein each of said arms comprises an area of said side between the second area and the central body portion that does not comprise said second material.
