  • Patent number: 11986561
    Abstract: In one aspect, compositions and wound dressings are described herein. In some embodiments, a composition or wound dressing described herein comprises a mesh formed from a plurality of biodegradable polymer fibers; a first active agent dispersed in the biodegradable polymer fibers; a plurality of biodegradable polymer particles disposed in the mesh; and a second active agent dispersed in the biodegradable polymer particles. The particles can be disposed within the interiors of the fibers of the mesh or between the fibers of the mesh. In another aspect, a composition or wound dressing described herein comprises a first perforated mesh formed from a first plurality of biodegradable polymer fibers; and a second perforated mesh formed from a second plurality of biodegradable polymer fibers, wherein the second perforated mesh is disposed on the first perforated mesh in a stacked configuration and the first and second perforated meshes have different degrees of perforation.
