Abstract:
1. A method for making a biocompatible, absorbable, implantable knitted silk mesh, comprising: depleting sericin from yarns; applying a first set of the yarns in a first wale direction on a single needle bed machine, each of the first set of yarns forming a first series of loops at each of a plurality of courses for a knitted mesh; applying a second set of the yarns in a second wale direction on the single needle bed machine, the second wale direction being opposite from the first wale direction, each of the second set of yarns forming a second series of loops at every other of the plurality of courses for the knitted mesh; and applying a third set of the yarns in every predetermined number of courses for the knitted mesh, the application of the third set of yarns defining openings in the knitted mesh, wherein the first set of the yarns interlaces with the second set of the yarns at the every other course to define nodes for the knitted mesh, and the second set of the yarns has a greater tension than the first set of the yarns, the difference in tension substantially preventing the knitted mesh from unraveling at the nodes, wherein the first, second, and third sets of the yarns are formed from silk, thereby making the biocompatible, absorbable, implantable, knitted silk mesh.
