Patent ID: 8500704

Claim:
A wound packing for application to a wound under a cover, the cover establishing a confined space in which said wound packing is located and to which suction is applied to remove wound exudates from the wound and from said wound packing while said wound packing is in place, said wound packing promoting wound contraction along an axis, said wound packing being arranged for facilitating the transfer of wound exudates from the wound and from said wound packing, said wound packing comprising a plurality of biocompatible nonabsorbent fibers coupled together to form a nonabsorbent anisotropic structure having a first compressive response along a first axis and a second compressive response along a second axis perpendicular to the first axis, the second compressive response being different from the first compressive response, wherein said nonabsorbent anisotropic structure further has a third compressive response along a third axis, the third axis being perpendicular to each of the first and second axes, the third compressive response being different from at least one of the first and second compressive responses, wherein the first compressive response is characterized by a first composite modulus of elasticity of 0.9 pounds per square inch, the second compressive response is characterized by a second composite modulus of elasticity of 3.7 pounds per square inch, and the third compressive response is characterized by a third composite modulus of elasticity of 1.0 pounds per square inch.
