Claim 0:
1. A single-layer polymeric mesh consisting of one layer having essentially identical first and second sides, the one layer consisting of two fiber types co-knit to form single layer;
a) wherein the first fiber type consists of an absorbable polymeric multifilament fiber, the absorbable polymeric multifilament fiber providing from 30% to 60% by weight of the single-layer polymeric mesh; and
b) the second fiber type consists of a non-absorbable synthetic monofilament polymeric fiber, the non-absorbable synthetic monofilament polymeric fiber selected from polyethylene with a denier of 60-150 g/9000 m or polypropylene with a denier of 130-180 g/9000 m, wherein said non-absorbable synthetic monofilament polymeric fiber has an ultimate elongation of greater than 30%;
wherein said absorbable polymeric multifilament fiber is warp knit with said non-absorbable synthetic monofilament fiber to form said single layer polymeric mesh, where the absorbable fiber is knit in a 2 bar marquisette pattern and the non-absorbable fiber is knit in a 2 bar sand-fly net pattern with all guide bars for each pattern threaded 1-in and 1-out;
wherein said absorbable fibers are interlaced with said non-absorbable fibers and at least partly traverses the non-absorbable fibers such that the absorbable fibers restrict uniaxial and multiaxial movement by said non-absorbable fibers; and
wherein said single layer warp-knit mesh has at least two different strength profiles including an initial stiff phase prior to degradation of the absorbable polymeric multifilament fiber and a later extensible phase that results after degradation of the absorbable polymeric multifilament fiber.
