Hernia repair device and methods

A hernia repair device, the hernia repair device comprised of two layers of material,

• the first layer of material, an upper layer, comprised of a silicone membrane, the second layer, a lower layer, comprised of a woven polypropaline fiber fabric,
• the silicone membrane selected in a thickness from 0.001″ to 0.005″,
• the upper layer possessing a plurality of slits in its surface, said slits made after the two layers are joined together, said slits in a regular pattern, the regular pattern comprising alternating perpendicular orientation, both horizontal and vertical,
• the lower layer woven in a regular pattern with weft knitting using a 1×1 alternating stitch, the slits on the surface either following the weft direction of the lower layer or crossing the weft direction of the lower layer perpendicularly,
• said upper layer or said lower layer or both the upper and lower layers treated with a plurality of layers of medicinal or therapeutic substances, said lower layer and optionally said upper layer also treated with a water soluble or water insoluble anti-scar compound,
• said slits placed in said upper layer such that the hernia repair device has essentially zero porosity with no stretching tension placed on it, the porosity of said hernia repair device variable proportional to the amount of stretching tension and the direction in which said stretching tension is placed on the hernia repair device,
• the direction of stretching tension dependent on the orientation of said slits with the weft orientation of a woven fiber fabric,
• the hernia repair device designed to place the woven nylon fabric side towards the abdominal wall when in use.
